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)

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.

• Articulatory phonetics deals with the identification and classification of individual sounds. It attempts to provide a framework of the nature of speech sounds and how they are produced.
• Auditory phonetics is concerned with the
perception of speech. According to Ball
and Rahilly (1999:178), the listener must
perceive or hear the speech signal and
• A transcription records as many features of an utterance as can be ascertained by the person doing the recording is called a narrow transcription. It captures the exact articulatory details of each sound. However, for many users, a less subtle transcription is perfectly suitable. A transcription that omits many of the irrelevant and predictable details of pronunciation is called a broad transcription. To indicate narrowing detail, the IPA offers a set of diacritics..

learners of English, and explain why they cause difficulty. 2. Observe your classmates’ pronunciation of the English consonant
[v] and write a short paper on the problem in the acquisition of [v] and how to solve it.
Phonetic features and natural classes
Teaching Aims
The Study of Speech Sounds
1. To make students familiar with sound production mechanism， the transcription and description of English sounds. 2. To make students understand the differences of consonants and vowels, the nature of phonetic features and natural classes. 3. To cultivate students’ cross-cultural awareness and research interests in discovering the regularities of speech sounds.
