Articulatory Phonetics (发声语音学)
(Linguists’ interest)
studies from the speaker’s point of view, how speaker uses his organs to articulate sounds. Articulatory Phonetic description generally makes reference to six main factors: Air stream – vocal folds – soft palate – place of articulation – manner of articulation – lips Or two major factors: speech organs + articulation (place + manner)
How many segments /sounds in a word?
cough, bough, dough ? Meat, great, threat, Sea, bead, dead ？

To make a speech sound visible so that we can measure its components objectively we must then go into the domain of acoustic phonetics, which studies the physical properties of speech sounds, as transmitted between mouth and ear.
3.1.2 Places of articulation
In terms of place of articulation, the English consonants can be classified into the following types:
bilabial
labiodental
j
4. Vowels (refer to Poole, 2000: 60)
4.1 cardinal vowels 基本元音(refer to Poole, 2000: 50-51)
British phonetician Daniel Jones first fixed the qualities of the two vowels which were produced with the tongue is as high and as far forward as possible in [i]. Another, represented by [a], is the sound produced when the tongue is as low as possible at the back. The other six vowels have been plotted down between these two extremes, the front vowels being plotted at equal acoustic distances as are the back vowels.

当声带分离时，气流容易通过，由此产生的语 音叫清音（voiceless），如 [p, s, t]。 当声带贴近时，气流使其产生震动 （vibration），形成的声音成为浊音 （voicing），如[ b, z, d]。 当声带完全紧贴时，气流无法通过，不发出声 音。

pharyngeal cavity: Vibration of the vocal cords results in a quality of speech sounds called voicing, which is a feature of all vowels and some consonants in English.

《语言学教程》Chapter2phoneticsIntroduction to Phonetics:Speech Sounds and the International Phonetic Alphabet (IPA): Articulatory Phonetics:Articulatory phonetics focuses on how speech sounds are produced and articulated by the vocal organs. These organs include the tongue, lips, teeth, and vocal cords. The sounds are produced by manipulating these organs to create different configurations and airflow patterns. For example, the sound [p] is produced by closing the lips and then opening them to release a burst of air.Acoustic Phonetics:Acoustic phonetics analyzes the physical properties of speech sounds in terms of sound waves and their frequencies. Sound waves are vibrations that travel through the air and reach our ears, where they are processed and interpreted as speech sounds. Different speech sounds have distinct acoustic properties, such as their pitch, loudness, and duration. These properties are measured and analyzed to better understand the characteristics of each sound.Auditory Phonetics:Auditory phonetics investigates how speech sounds are perceived and processed by the human auditory system. When we hear speech sounds, our ears detect the sound waves and send them to the brain for interpretation. The brain then matches these signals to specific speech sounds and recognizes their meaning. Auditory phonetics explores the mechanisms and processes involved in this perception and interpretation.Segmental and Suprasegmental Features:In linguistics, speech sounds can be classified into two categories: segmental and suprasegmental features. Segmental features pertain to individual sounds or phonemes, while suprasegmental features refer to properties that extend beyond individual sounds, such as stress, intonation, and rhythm. These suprasegmental features contribute to the melody and rhythm of speech and can carry additional meaning and emphasis.Phonetic Transcription:Conclusion:。

What is Phonetics?
Phonetics (语音学) studies how speech sounds are produced, transmitted, and perceived. It is concerned with all the sounds that occur in the world’s languages.

Performance
Performance is often influenced by psychological and social factors; it is not stable.
A speaker’s performance does not always match or equal his supposed competence. Chomsky believes that linguists ought to study competence, rather than performance. In other words, they should discover what an ideal speaker knows of his native language.

Approximants are therefore more open than fricatives. e.g. central: [r] or lateral [l] in lip; semi-vowel approximants: [j] [w] in yes and well
5. Trills （颤音）and taps （触音） Trill: involves a series of rapid repetition of one articulator striking another. E.g., English 'r' in some Scottish accents. Tap (or 'flap' or 'flick'): a momentary variant of the trill. It involves a single rapid contact between one articulator and another without repetition. E.g. /r/ in AmE better.

English consonants can be classified in terms of manner of articulation
Fricatives (摩擦音) A fricative is the type of consonant that is formed by forcing air through a narrow gap so that a hissing sound is created. /f/ in fin, / θ / in thin, / ʃ / in shin. /v/ in van, /s/ in sin, /h/ in hat, / θ / in that, /z/ in zoo and / ʒ / sound in genre.

fricatives

When the obstruction is partial and the air is forced through a narrow passage in the mouth so as to cause definite local friction at the point.[f][v][s][z]…(p.53)
Classification of English speech sounds:
Vowels (20):
the sounds are produced when the air-streams meet no
obstruction of any kind in the throat, the nose, or the

Stops:or plosive consonants:

When the obstruction created by the speech organ is total or complete, the speech sound produced with the obstruction audibly released and the air passing out again is called a stop or a plosive: [p][b][t][d][k][g]

There are two kinds of transcription: narrow transcription and broad transcription. A narrow transcription records as many features of an utterance as possible. This is the transcription needed and used by the phoneticians in their study of speech sounds. A broad transcription omits many of the irrelevant and predictable details of pronunciation . This is the transcription normally used in dictionaries and textbook for general purposes.

• Phonetics is of a general nature; it is interested in all the speech sounds used in all human languages: • how they are produced, how they differ from each other, what phonetic features they possess, how they can be classified, etc. • Phonology, on the other hand, aims to discover how speech sounds in a language form patterns and how these sounds are used to convey meaning in linguistic communication.
• [t] and [d] are thus important sounds in English, because they enable us to distinguish tin and din, tie and die, and many more word pairs. • Similarly, [f] and [d] can be shown to be important units too, because they distinguish between fish and dish, fine and dine and many other pairs.
Phonetics & Phonology
Phonetics: Speech Sounds
• Speech and writing are the two media or substances used by natural languages as vehicles for communication. Many languages in the world today are both written and spoken. • Language is first perceived through its sounds. Thus the study of sounds is of great importance in linguistics. Naturally, linguists are not interested in all sounds; they are concerned only with those sounds that are produced by humans through their speech organs and have a role to play in linguistic communication.
• A phoneme is a phonological unit; it is a unit that is of distinctive value. It is an abstract unit. It is not any particular sound, but rather it is represented or realized by a certain pholophone: different phones which can represent a phoneme in different phonetic environments are called the allophones of the phoneme • Phone(音素）: phonetic unit or segment
• Vowels may be distinguished as front, central, and back according to which part of the tongue is held highest. • i.e. A front vowel is one in the production of which the front part of the tongue maintains the highest position • English consonants can be classified in two ways: one is in terms of manner of articulation and the other is in terms of place of articulation.
• In minimal pairs, we can always identify two ―key‖ sound segments that semantically distinguish one word from the other, the two key sounds are therefore ―contrastive‖ in meaning. They are in contrastive distribution. • The two sounds are functioning in language by distinguishing meaning, because the replacement of one with the other will result in meaning change.
Speech sounds
• These sounds are limited in number. This limited range of sounds which are meaningful in human communication constitute the phonic medium of language, and the individual sounds within this range are the speech sounds（言语语音）.
Classification of English speech sounds
English speech sounds are generally classified into two large categories: • Vowels • Consonants • Note: The essential difference between these two classes is that in the production of the former the airstream meets with no obstruction of any kind in the throat, the nose or the mouth, while in that of the latter it is somehow obstructed.
• For instance, the word tin in English consists of three separate sounds, each of which can be given a symbol in a phonetic transcription, [tin]. If we replace [t] by [d], a different word results: din.
Phonology: Sound Patterns
• Both phonology and phonetics are concerned with the same aspect of language -- the speech sounds. But while both are related to the study of sounds, they differ in their approach and focus.
• For example, when we pronounce the two words peak and speak, we are aware that the sound [p] is pronounced differently. • In the word peak, the [p] sound is pronounced with a strong puff of air stream; but the same stop sound is pronounced slightly differently in the word speak; the puff of air is withheld a little.
These three branches of phonetics
• articulatory phonetics （发音语音学） • it studies the sounds from the speaker's point of view, i.e. How a speaker uses his speech organs to articulate the sounds. • auditory phonetics（听觉语音学） • It looks at the sounds from the hearer's point of view, i.e. How the sounds are perceived by the hearer. • acoustic phonetics（声学语音学） • It studies the way sounds travel by looking at the sound waves, the physical means by which sounds are transmitted through the air from one person to another.
Minimal pairs (最小对立体）
• Phonological analysis relies on the principle that certain sounds cause changes in the meaning of a word.
