基于STM32系统的智能语音控制的垃圾桶设计苏珍康学亮马飞虎（北方民族大学，宁夏银川750021）摘要：随着计算机技术与电子科技的快速发展，人工智能、云计算等技术的不断进步，智能家居新型产业模式也得到了巨大的发展，至今国内智能家居市场投资达到了1396亿元，市场规模占比不断增大，未来十年内家居智能化将实现大规模应用。

鉴于此，设计了一种智能语音控制垃圾桶，能根据人发出的指令做出判断，运行到指定位置，收取完垃圾之后再回到起点位置。

关键词：智能家居；STM32；嵌入式；人工智能0引言随着人们生活起居水平的提高、社会的发展和经济水平的不断提升，人们对生活的要求更趋于个性化、定制化、自动化，对生活的便捷及乐趣有了更高的要求。

在平时生活中，扔垃圾是再简单不过的一件事情，但也会给人们带来不必要的麻烦。

比如，吃东西的时候不想走动，但也不想放一个垃圾桶在身边。

为解决这样的问题，此项目设计了一款能用语音控制、自动寻迹的垃圾桶。

该设计的主控系统采用STM32单片机，能够识别特定的语音指令，将语音信息转换为电信号给主控系统进行处理，主控系统在处理语音信息的基础上，判断在哪个位置有人需要，不再需要人们特意走动到垃圾桶边去扔垃圾。

1总体设计此项目所设计的智能语音控制的垃圾桶，是采用YS -V0.7语音识别模块来识别特定的语音指令，经STM32控制系统的数据处理做出判断，再通过寻迹系统去到指定的位置。

在寻迹的过程中，用16位的数字陀螺仪检测记录位置，对走过的轨迹做虚拟标记，再对虚拟标记进行数据处理，形成一个记忆系统，使接下来的寻迹判断更加灵敏，如图1所示。

2系统硬件设计2.1STM32F10X 主控系统STM32是ST 公司设计的一款常用的增强型系列微控制器，STM32F10X 系列产品属于中低端的32位基于ARM 系统的微控制器，其内核是Cortex -M3，常用于微控制、电机驱动、嵌入式系统开发等方面。

2.2MPU6050六轴陀螺仪在寻迹计算运动轨迹的过程中，判断左右移动的位移量，我们采用现在市场上最常用的六轴数字陀螺仪[1]MPU6050模块，此模块集成有三轴陀螺仪、三轴加速度计，通信方式为常用的IIC 通信协议，芯片内置16位的AD 转换器和16位数据输出，在精度上完全能够达到要求，并且降低了算法复杂度。

一种基于Arduino的智能家居控制系统一种基于Arduino的智能家居控制系统摘要：介绍了一种基于Arduino的智能家居控制系统,利用Arduino作为主控系统,结合传感器技术、GSM通信技术、语音控制技术等实现对家居环境中的温湿度、空气质量、照明设备、家电设备等的智能控制。

该系统具有无线控制的功能，操作方便，成本低，适合大量推广使用。

关键词：Arduino；智能家居；无线控制1984年世界上第一幢智能建筑在美国康涅迪格州出现。

它将家庭中各种与信息相关的通信设备、家用电器和家庭保安装置连接到一个家庭智能化系统中进行集中的或异地的监视、控制和家庭事务性管理，并保持这些家庭设施与住宅环境的和谐与协调[1]。

如今这种建筑正成为都市人青睐的家居体验方式。

2003年以来，海信、清华同方等公司也相继加入到智能家居行列，但目前的智能家居系统还缺乏统一明确的国际标准，许多公司开发出的产品都是基于自己组建的网络和信息交换协议，很多产品是针对特定的组网环境开发的，部分核心技术没有对外公布，技术复杂，直接导致了使用范围的局限性。

由于缺乏对应的第三方产品，各个接入设备之间不能兼容，互操作性差，不利于产品的扩充。

1系统的硬件设计以电子系统为核心的家居系统是未来智能家居的发展趋势[2],本文介绍一种基于Arduino 的智能家居控制系统。

建立智能家居控制系统，硬件是关键和基础，它对整个系统的稳定性、控制和反馈的准确性、节能性都有直接影响[3]。

智能家居控制系统的硬件部分主要包括Arduino控制器、传感系统、无线控制系统、语音播报部分和液晶显示等。

其中，传感器部分由温湿度传感器和气体传感器三部分组成，用以检测室内温湿度及有害气体。

无线控制部分由GSM和无线语音控制模块两部分组成。

系统结构。

1.1Arduino控制器Arduino是一个开源的单片机电子设计平台，硬件部分由Atmel AVR单片机、I/O接口及相关电路组成，软件部分则包括标准的程序编译器和程序下载器，具有使用类似Java 和C语言的Processing/Wiring开发环境[4]。

MIX7MIX7 is a 7-channel mono summing mixer in Eurorack format that can be used to mix audio, CV, Triggers or Gate signals. There are two modes of operation that are set by a jumper at the back of the module.Unity gain (JUMPER OFF: OUT = IN): The level of each input equals that of the output, what comes in comes out.Attenuated gain (JUMPER ON: OUT = 0.4IN): The level of each input is attenuated at the output to provide more headroom for mixing hot (loud) audio signals without distortion.The module is shipped in Unity mode, with the jumper o .MIX7 can be used in multiple ways, so lets get started:Drum MixerSequence a drum pattern with up to 7 drum sounds, connect the audio output of each drum module to an input of MIX7. Connect the output of MIX7 to your sound system. Use individual volume controls on drum modules to set the drums balance.Mixing Oscillators WaveformConnect the waveforms from two Z3000’s to the inputs of MIX7. Connect the mix output of MIX7 to your sound system through a Filter like the Z2040. You have just patched the audio part of a monophonic synth patch.Mixing Control Voltage SourcesIn this example we will need two Z4000 envelopes. Connect the outputs of both to the inputs of MIX7. Connect the mix output of MIX7 to your Frequency Modulation (FM) input of Z2040 lter. Now you can modulate the lter frequency with two envelopes.Mixing Triggers And GatesConnect the trigger outputs from your Circadian Rhythms or Trigger Riot to di erent inputs on the MIX7, send the MIX OUT to a Tiptop Audio ONE Sample Player, play with the Mute button on the sequencers to add and remove triggers from the mix.Mixing More Than 7 ChannelsMIX7 is a summing bus that can be expanded by using two or more MIX7 modules to add channels. Connect the output of the rst MIX7 to input 1 on the second MIX7. Connect the output of the second MIX7 to your sound system. Now you have patched a 13-channel mixer.Modes And Jumper SettingsThere are two modes of operation that are set by a jumper at the back of the module. With the jumper set on one pin or none of the pins the mode is set to Unity Gain, this is how your MIX7 is set by us when shipped to you. With the jumper set on two pins the mode is Attenuated Mode. On the back of the module the options appear as:JUMPER OFF: OUT = INJUMPER ON: OUT = 0.4 INMode 1 - Unity gain: the level of each input equals that of the output, what comes in comes out. This is the standard mode typical to modular synthesizer mixers. This mode is transparent with no added gain and can be used with all type of signals.Mode 2 - Attenuated Gain: the level of each input is attenuated before it gets mixed to provide more headroom for mixing hot (loud) audio signals without distortion. This mode should be con-sidered if you are planning to use MIX7 primarily for mixing hot signals like Tiptop drums and ONE Sample Player modules, giving you peace of mind knowing there is little chance of clipping the signals even when the volume levels of the sounds feeding the mixer are high. Mixing of audio signals with no distortion and clipping is essential for quality mixing, for example when mixing bass drums. In many cases bass drums are pure sine waves. If these waves are getting clipped, the bass drum gets added harmonics that change its purity. This can lead to a unintentionally distor-ted bass drum instead of a well-rounded one. Clipping is indicated by the RED led on the module.Mode 1Mode 2Processing Drums In GroupsBy using two or more MIX7 it’s easy to create ''subgroups''. Subgroups are used to process groups of di erent sounds simultaneously. For example you can mix bass drums, toms and snare together using one MIX7 and Hi Hats and cymbals using another MIX7.1. Connect the output of the rst MIX7 to a High Pass input on Forbidden Planet and theoutput of the second MIX7 to a delay.2. Connect MIX7 outputs to the inputs on a third MIX7.3. Connect the output of the third MIX7 to your sound system.Now you have split your drum sounds into two separate processing groups: High-Pass lter on low and mid-range drums and delay on cymbals and hi hats. This is a typical work ow of signal routing and sound design inside the modular.Mixing Oscillator Waveforms1. Tune your Z3000 oscillator to a nice bass frequency.2. Connect square wave to input 1 on MIX7.3. Connect sine wave output of a second Z3000 tuned one octave lower than the rst tochannel 2 of MIX7.4. Connect mix output of MIX7 to the input of Z2040 lter.5. Connect the output of Z2040 to your sound system.Now you have a square wave tone reinforced by a sub bass sine wave that you can lter to taste.A variation on the patch described above.1. Tune your Z3000 oscillator to a nice bass frequency.2. Conne.ct square wave output to the input of Z2040.3. Connect the output of Z2040 to input 1 on MIX7.4. Connect sine wave output of a second Z3000 tuned one octave lower than the rst tochannel 2 of MIX7.5. Connect mix output of MIX7 to your sound system.Now you have a square wave tone that you can lter to taste reinforced by a sub bass sine wave that is ltered separately.Mixing Control Voltages1. Connect saw wave output of Z3000 to the audio input of Z2040, connect the output ofZ2040 to your sound system.2. Connect the output of Z4000 ADSR envelope to input 1 on MIX7.3. Connect the output of a second Z4000 to input 2 on MIX7.4. Connect the output of a third Z4000 to input 3 of MIX7.5. Connect the 16 step output of Z8000 to input 4 of MIX7.6. Connect the mix out of MIX7 to the frequency modulation input of Z2040.Trigger the 3 envelopes from 3 separate tracks of Circadian Rhythms, clock Z8000 from the main Circadian Rhythms clock output. Now run the sequence. By creatively arranging your gate patterns that trigger the envelopes and mixing in modulation sequence you cancreate very interesting modulation patterns.Connect The Sound Of Your Mobile Phone To Your ModularMIX7 can even be used to amplify a weak signal. It’s not the ideal way of doing that, but what hap-pens if you don’t have a dedicated ampli er module handy? Use Stackcables to send your phone audio to all 7 inputs on MIX7, (make sure MIX7 is set to UNITY MODE). MIX7 has now multiplied the gain of your phone by 7, making it usable for use in the modular.。

You can set it up to recognize over 200 voice commands and have the onboard STM32F415RG MCU carry them out. It works by matching sounds with pre-recorded commands. Sound is received through an onboard microphone and then processed bya VS1053 IC with a built in stereo-audiocodec. The SpeakUp comes witha dedicated software tool foreasy configuration. The board islined with 12 user programmable GPIOsfor standalone functionality. It also carries a standard mikroBUS™ host socket.Easy configuration Over 200commandsUltra fastoperationStandalonemodeWouldn't you rather issue verbal commands and have your machines comply, instead of pressing keys, pushing buttons and flipping switches all the time? There's a wide range of applications for the SpeakUp.Command your lights, doors and home appliances.Create voice commanded remotes for TVs or media centers.Reduce complexity and cost of control interfaces.When doing something with both hands and voice command is the only option.Package dimensions:L 70mm, W 60mm, H 30mm BoxUser manual1x8 headersSpeakUp click ™ boardRecycle Bin documentPackage weight:~40gBefore using your click ™ board on your target platform, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package.Turn the board upside down so that the bottom side is facing you upwards. Place shorter pins of the header into the appropriate soldering pads. Turn the board upward again. Make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully.Now you need to train your SpeakUp to obey your commands. Plug in the board to your PC through USB cable. Configure it using the free software (see page 12). Alternatively you can configure the board directly using the on-board buttons (see page 24).1. Prepare it2. Configure itThe SpeakUp now understands your commands. Connect relays, motors or other electronic actuators directly to SpeakUp’s GPIO pins. Alternatively plug the SpeakUp into any board or shield carrying a mikroBUS ™ socket. You can now control your devices with your voice.3. Use itAlong with its key components, the SpeakUp packs other useful bits like two buttons for recording or deleting voice commands manually, whilethree signal LEDs give recognition feedback and indicate power.Line out pads USB connector Audio jackMicrocontroller mikroBUS connector(STM32415RG)Microphone12 GPIOs25.40 mm 57.15 m m 10.30 mm (user programmable)1000 mils2550 m i l s405.50 milsAudio Codec (VS1053)Signal LEDs Push-buttons JTAG connector7Input:Output:What gives the SpeakUp its speech recognition capabilities is the firmware we developed for the on-board MCU. It’s based on the DTW algorithm, which makes it decisive, it turns your talk into action almost instantly.Sound is received through an on-board microphone. There’s also a 3.5mm jack for connecting an external microphone.After the processed sound has been forwarded to the STM32F415RG MCU that interprets the voice command, there are two output options which can be utilized at the same time or separately:STANDALONE MODE:On-board MCU directly controls external devices using 12 user programmable GPIOsCLICK ™ MODE:Sends index of the matched voice command to a selectable interface: USB or UART.Between the mic and the MCU sits a VS1053 IC with a built in stereo audio codec to process the raw signal.SpeakUp Firmware AlgorithmThe main goal of a speech recognition system is to substitute a human listener, although it is very difficult for an artificial system to achieve the flexibility offered by human ear and human brain. The work principle of speech recognition systems is roughly based on the comparison of input data to prerecorded patterns. These patterns can be arranged in the form of phoneme or word. By this comparison, the pattern to which the input data is most similar is accepted as the symbolic representation of the data. It is very difficult to compare raw speech signals directly. Because the intensity of speech signals can vary significantly, a preprocessing on the signals is necessary. This preprocessing is called Feature Extraction.First, short time feature vectors are obtained from the input speech data, and then these vectors are compared to the patterns classified prior to comparison. The feature vectors extracted from speech signal are required to best represent the speech data, to be in size that can be processed efficiently, and to have distinct characteristics.The SpeakUp Firmware uses Dynamic Time Warping (DTW) algorithm - word-based, isolated word, speaker dependent and template matching algorithm :In the word based speech recognition the smallest recognition unit is a wordIn the isolated word recognition, words that are uttered with short pauses are recognized,Speaker dependent reference patterns are constructed for a single speaker,Template matching algorithm is a form of pattern recognition. It represents speech data as sets of feature/parameter vectors called templates. Each word or phrase in an application is stored as a separate template. The input speech is then compared with stored templates and the stored template most closely matching the incoming speech pattern is identified as the input word or phrase.The SpeakUp software configuration tool is a free PC application for configuring the SpeakUp click board. With it, you can configure the board to recognize over 200 different voice commands and have the on-board MCU carry them out instantly. You can download the software from the following link:The software is designed with ease of use and simplicity in mind. The UI is based on tabs and drop-down menus requiring no programming skills to use.Still, it has all the essential features and options that give you full control of the set-up process.Connect the SpeakUp click board to the computer via the USB cable. It will be recognized as a USB Human Interface Device (HID)in the Device Manager of the Control Panel.After the successful connection, the SpeakUp click ™ board will perform ambient noise detection and calibrate itself. The process lasts about 10 seconds. It’s done when the red signal LED turns off. After that the board is ready for recording voice commands. You can set custom calibration parameters for any subsequent usage in the Project Settings (see page 18).Ambient Noise DetectionOnce you connect the SpeakUp to your computer you’re just a few clicks away from configuring it. The set-up process is dead simple. Launch the application, and it will lead you through the initial steps of recording and assigning commands.To create a new project, press the Create New Project button from the main toolbarof the SpeakUp software.A new window will open, where you can enter your project’s name and destination folder (if the destination folder doesn’t exist, the software will prompt you to create it).To finish project creation after inputting the required information, press the Create button.Alternatively, you can choose to open the settings menu as soon as you create a project, by checking the appropriate box.To record a new voice command, press the Add New Voice Commandbutton. A New Voice Comand dialog window will appear. Press the Record button. The length of the recording is set in the Project Settings window (see page 18).The recorded command will be played back automatically, so you can make sure it’s OK.Add a voice command Record it Stay within the time limit Hear it backIf you’re satisfied with the recording, enter a name for your command and click the Save & Close button.The recorded command will appear as a new tab . You can play it back, edit or delete it anytime.If the SpeakUp fails to detect a voice command, your surrounding might be too noisy. Try again by speaking a bit louder. If it still doesn’t work, launch Settings and adjust the Noise treshhold .TroubleshootName it and save itYou’re done!General SettingsTo configure project settings, press the Open Settings Window button and the Settings window will open.In the General Settings you can configure the SpeakUp’s functionality:Acceptance threshold: This is the parameter you should adjust to define how closely your delivery has to match your pre-recorded command. At lower values, you’ll have to deliver the command precisely the way you recorded it. At higher values the matching doesn’t have to be so precise, but this increases the probability that the SpeakUp will pick up irrelevant speech and interpret it as a command. You should be able to reach the sweet spot value through some trial & error.Recording timeout: Timeframe in which the SpeakUp click board expects recording input after the record button is being pressed. User can choose between 5, 10 and 15 seconds timeframes.Word Length: Length of the voice command being recorded, in seconds. Can be 1, 1.5 and 2 seconds.Noise level: Minimal sound volume level that can trigger a voice command recognition. Lower values require quieter pronunciation, resulting in higher noise/hiss sensitivity. On the contrary, higher level values require louder pronounciation and they are less sensitive to noise/hiss. We recommend that you keep auto detection enabled. That way the SpeakUp Click board will measure the noise level, and perform noise calibration automatically. Auto detection can last a bit longer, usually around 10 seconds. Suddenchanges in sound levels will lengthen the time of calibration and will result in improper sound level values.Notify master: Notifies the master (MCU or PC) when the voice command is recognized by sending a 16-bit index number of voice command via chosen communication interface (UART or USB).Data rate: Sets the speed used for sending data to themaster (MCU or PC).Pin Aliases And Initial Pin StatesIn this section, you can rename GPIO pins according to your needs and set their starting conditions. The new GPIO pin aliases will be applied in the main window too. Set the corresponding initial GPIO pin state in the Initial Pin States section. Condition canbe either low (logical 0) or high (logical 1).When a new command is recorded, it is time to assign it an action. The action will be performed when the voice command is recognized. Also, a 16-bit index number of the voice command will be sent via chosen communication interface (UART or USB) .NONE: When this option is selected, no action will be performed on the corresponding GPIO pin upon voice command matching.ON: When this option is selected, a corresponding GPIO pin will be set to logical high state upon voice command matching.OFF: When this option is selected, a corresponding GPIO pin will be set to logical low state upon voice command matching.TOGGLE: When this option is selected, a corresponding GPIO pin state will be toggled upon voice command matching.PULSE: When this option is selected, a train of pulses will be sent to the corresponding GPIO pin upon voice command matching.There are five types of action that can be assigned :Pulse parametersThe pulse parameters can be set in the Pulse Parameters window (click on the Edit pulse parameters icon Edit pulse parameters to open it) :A period (T) is the time it takes for a signal to complete a single cycle (sum of thehigh state and low state time periods).Duty ratio (D) is the percentage of T in which a signal is active, i.e. ratio of the high state period and a complete period.N is the number of times the pulse is repeated.Thus, a 60% duty cycle means the signal is ON 60% of the time period but OFF 40% of the time period.8.7When you’re finished recording and configuring voice commands, it is time to upload the project to the SpeakUp click™ board. This is done via the Upload Project button.You can monitor the upload process in the Toolbar.After it’s done, an appropriate message will be displayed in the Status Bar.Each recorded voice command is given an index number which is sent to the host MCU. You can export voice command names and their indexes as constants. The exported document will be in the form of a source file (in any of the threelanguages), as shown below.You can perform some basic configuration directly on the SpeakUp without using the software. Different combinations of button presses will allow you to record, re-record or erase commands. You’ll get feedback from the on-board LEDs. However you won’t be able to assign specific actions with this method.Two indicator LEDs provide the following signals:Amber LED - the board is ready for recording or listening.Red LED - the board is perfoming an operation.When the voice command is recognized, both LEDs are lit for a half a second. On-board LEDsUse push-buttons to operate the board:Push-button 1 - To record your voice command,stay within the time limit for each command (default settings: 1 second). You can also record multiple commands at once by pronouncing them one by one while keeping the button pressed. Just make sure to wait for the red LED to flash between pronouncing subsequent commands. Proceed in this way for asmany commands as you need. Each command will be assigned a unique index.Push-button 2 - If you press it for more than 2 If both push-buttonsare pressed for moreOn-board push-buttons12Acceptance Threshold: 15 Recording Timeout: 5s Word Length: 1s Noise Level: Auto Notify Master: USBStandalone mode default settings:Here are some general recording Tips :For better recording results, it is necessary to provide conditions with lowest amounts of ambient noise and speaker distance from the microphone in the range from 10 to 20cm.If there are problems with the voice command detection, please record it several times due to the pronounciation diversity.It is mandatory to play back the recorded voice command in order to hear if some ambient noise was recorded also.Because of this, it is recommended that the SpeakUp click™ board is placed on a surface that doesn’t transfer mechanical vibrations.This is a speaker dependent system. If there are more users, each person should record voice commands separately, due to the pronounciation diversity.Number of voice commands that can be recorded depend on their lengths, typically more than 200 for the voice command length of 1 second.Please keep in mind that the recording is performed by the SpeakUp click™ board, not the computer, so there is no need to connect an external microphone to the computer.SpeakUp has a world of applications. It’s up to your imagination to come up with the coolest ideas. Here’s a hint or two:Use SpeakUp on top of the Pi click Shield to command XBMC Home Media Center on Raspberry Pi®. It’s a great a replacement for a mouse and a keyboard.Replace your lamp switch with a SpeakUp click and a relay. Tell your light to turn ON or OFF if your hands are busy doing something important.If you want to learn more about our products, please visit our website at If you are experiencing some problems with any of our products or just need additional information, please place your ticket at /support/If you have any questions, comments or business proposals,do not hesitate to contact us at *****************。

Voice Recognition Module V3 Speak to Control (Arduino compatible)OverviewELECHOUSE Voice Recognition Module is a compact and easy-control speaking recognition board.This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command.This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.What’s new?We already have Voice Recognition module V2. It supports 15 commands in all and only 5 commands at the same time.On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at thesame time.On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.Parameter●Voltage: 4.5-5.5V●Current: <40mA●Digital Interface: 5V TTL level for UART interface and GPIO●Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface●Size: 31mm x 50mm●Recognition accuracy: 99% (under ideal environment)Feature●Support maximum 80 voice commands, with each voice 1500ms (one or two words speaking)●Maximum 7 voice commands effective at same time●Arduino library is supplied●Easy Control: UART/GPIO●User-control General Pin OutputTerminology●VR3 -- Voice Recognition Module V3●Recognizer -- a container where acting voice commands (max 7) were loaded. It is core part ofvoice recognition module. For example, it works like “playing balls”. You have 80 players in your team. But you could not let them all play on the court together. The rule only allows 7 playersplaying on the court. Here the Recognizer is the list which contains names of players working on the court.●Recognizer index -- max 7 voice commands could be supported in the recognizer. Therecognizer has 7 regions for each voice command. One index corresponds to one region: 0~6●Train -- the process of recording your voice commands●Load -- copy trained voice to recognizer●Voice Command Record -- the trained voice command store in flash, number from 0 to 79●Signature -- text comment for record●Group -- help to manage records, each group 7 records. System group and user group aresupported.InstructionHere we will introduce the Arduino Library and VR3 ProtocolFor ArduinoPrepare●Voice Recognition V3 module with microphone●Arduino board (UNO recommended)●Arduino Sensor Shield V07 (optional)●Arduino IDE●Voice Recognition V3 library (Download zip file)Hardware and Software Preparation1.Connect your Voice Recognition V3 Module with Arduino, By Default:2.Download VoiceRecognitionV3 library. (download zip file or use g i t c l o n eh t t p s://g i t h u b.c o m/e l e c h o u s e/V o i c e R e c o g n i t i o n V3.g i t command)3.If using zip file, extract VoiceRecognitionV3.zip to A r d u i n o S k e t c h\l i b r a r i e s folder, or if youuse g i t c l o n e command copy VoiceRecognitionV3 to A r d u i n o S k e t c h\l i b r a r i e s .Train1.Open vr_sample_train (File -> Examples -> VoiceRecognitionV3 -> vr_sample_train)2.Choose right Arduino board(Tool -> Board, UNO recommended), Choose right serial port.3.Click Upload button, wait until Arduino is uploaded.4.Open Serial Monitor. Set baud rate 115200, set send with Newline or Both NL & CR.5.Send command s e t t i n g s(case insensitive) to check Voice Recognition Module settings.Input s e t t i n g s, and hit E n t e r to send.6.Train Voice Recognition Module. Send s i g t r a i n0O n command to train record 0 with signature"On". When Serial Monitor prints "Speak now", you need speak your voice(can be any word, meaningful word recommended, may be 'On' here), and when Serial Monitor prints "Speak again", you need repeat your voice again. If these two voice are matched, Serial Monitor prints "Success", and "record 0" is trained, or if are not matched, repeat speaking until success.What is a signature? Signature is a piece of text description for the voice command. Forexample, if your 7 voice command are “1, 2, 3, 4, 5, 6, 7”, you could train in the following way: s i g t r a i n0o n es i g t r a i n1t w os i g t r a i n2t h r e es i g t r a i n3f o u rs i g t r a i n4f i v es i g t r a i n5s i xs i g t r a i n6s e v e nThe signature could be displayed if its command was called.When training, the two led on the Voice Recognition Module can indicate your training process.After sending the training command, the SYS_LED (yellow) is blinking fast which remind you to get ready. Speak your voice command as soon as the STATUS_LED (red) light lights on. The recording process ends once when the STATUS_LED (red) lights off. Then the SYS_LED is blinking again, get ready for next recording process. When the training process ends successful, SYS_LED and STATUS_LED blink together. If the training fails, SYS_LED and STATUS_LED blink together, but quickly.7.Train another record. Send s i g t r a i n1O f f command to train record 1 with signature "Off".Choose your favorite words to train (it can be any word, meaningful word recommended, may be'Off' here).8.Send l o a d01 command to load voice. And say your word to see if the Voice RecognitionModule can recognize your words.If the voice is recognized, you can see.9.Train finish. Train sample also support several other commands.Control LED SampleHere we show a simple example showing how to control the LED on Arduino board(connecting to pin13)through voice commands.Before this example,you need to train the VR module first in the way as vr_sample_train shows above. Use the following commands:●s i g t r a i n0o n Train the voice command used to light on the LED●s i g t r a i n0o f f Train the voice command used to turn off the LEDThen following the steps:1.Open vr_sample_control_led (File -> Examples -> VoiceRecognitionV3 ->vr_sample_control_led)2.Choose right Arduino board (Tool -> Board, UNO recommended), Choose right serial port.3.Click Upload button, wait until Arduino is uploaded.4.Open Serial Monitor. Set baud rate 115200.5.You will see the indication:Speak the voice commands you train above and check the status of LED on Arduino.vr_sample_multi_cmdThis sample shows how to use multi commands (more than 7 commands). This sample use RECORD 0 (the first voice command) to switch between the 2 command 'groups' (not Voice Recognition Group Function). Group 1 is made of RECORD 0, 1, 2, 3, 4, 5, 6. A nd second group is made up of RECORD 0, 7, 8, 9, 10, 11, 12 .Note: Before start this sample, you need train your Voice Recognition module first, and make sure that all records from 0 to 12 should be trained.vr_sample_check_baud_rateThis sample is used to check the baud rate, when you forgot your custom settings.vr_sample_bridgeThis example allows you to send VR3 protocol commands to VR3 board. For more detail, please refer to Protocol . Note: do not input Frame Head, Frame Length, Frame End, only need input Frame Command and Frame Data. For example, Check Recognizer Command is "AA 02 01 0A" for all, here you only need input 01.Example:1.Enable Arduino Serial monitor "Send with newline", Baud rate 115200.2.Input "01" to "check recognizer".3.input "31" to "clear recognizer"4.input "30 00 02 04" to "load record 0, record 2, record 4"Please refer to libref.pdf to get more information about functions of this library.VR3 ProtocolVR3 protocol contains basic commands to control VR3 boards. For those who use VR3 with other MUC rather than Arduino, VR3 protocol is very helpful.All the commands of VR3 are sent through serial port in HEXADECIMAL FORMAT.Example are supplied with this serial port tool: Access PortTo connect VR3 to PC, this USB-TTL module tool: USB-TTL Module with 5V or 3.3VBase FormatControl| Head (AA) | Length| Command | Data | End (0A) |Length = L(Length + Command + Data)Return| Head (AA) | Length| Command | Data | End (0A) | Length = L(Length + Command + Data)NOTE: Data area is different with different with commands.
