Chapter 2 Speech Sounds Phonetics and Phonology Phonetics: the study of sounds The production of speech The sounds of speech The description and classification of speech sounds, words and connected speech, etc. It focuses on chaos.

Phonetics studies the characteristics of human speech sounds and provides methods for their description, classification and transcription.

Speech Sounds Phonology: the study of sound patterns The rules governing the structure, distribution, and sequencing of speech sounds and the shape of syllables It deals with the sound system of a language by treating phoneme as the point of departure. It focuses on order.

Speech Sounds Three mains areas in phonetics Articulatory phonetics: the production of speech sounds Acoustic phonetics: the physical properties of the sounds produced in speech Auditory phonetics: the perception of speech sounds

Speech Sounds Speech organs (Vocal organs) LUNGS TRACHEA THROAT (Pharynx and Larynx) NOSE MOUTH (Tongue and parts of palate)

Three cavities of the VOCAL TRACT Pharynx （咽腔） Mouth (ORAL CAVITY) Nose (NASAL CAVITY) The energy sources of speech sounds is an AIRSTREAM.

VOICELESS and VOICED Voiceless: When the vocal folds are apart, the air can pass through easily. Voiced: When the vocal folds are closed together, they are caused to be vibrated by the airstream.

The Upper Part of the mouth UPPER LIP UPPER TEETH ALVEOLAR RIDGE： 齿龈 HARD PALATE： 硬腭 SOFT PALATE ( VELUM)：软腭 UVULA：小舌

The Bottom Part of the mouth LOWER LIP LOWER TEETH TONGUE (TIP, BLADE, FRONT, BACK, and ROOT) MANDIBLE （下颚/下颌）

Phonetic transcription IPA ( International Phonetic Alphabet) The first version of the IPA - In 1886, proposed by Otto Jespersen - In 1888, the first version of the IPA was published The present system of the IPA: In 1920s, by Daniel Jones The latest version of the IPA: in 1993 (revised) and in 1996 (corrected)

Consonants Manners of articulation STOP (PLOSIVE) ：塞音（爆破音） NASAL：鼻音 FRICATIVE：擦音 APPROXIMANT：通音（近音） LATERAL：边音 AFFRICATE：塞擦音

Places of articulation Bilabial：双唇音 Labiodental：唇齿音 Dental：齿音 Alveolar：齿龈音 Postalveolar：后龈音 Palatal：硬颚音 Velar：软腭音 Glottal：声门音

Description of English consonants [p]: voiceless bilabial stop [b]: voiced bilabial stop [s]: voiceless alveolar fricative [z]: voiced alveolar fricative

Vowels Four criteria to description of vowels FRONT, CENTRAL, and BACK : the part of tongue that is raised) HIGH, MID (MID-HIGH, MID-LOW), and LOW：the extent to which the tongue rises in the direction of the palate ROUNDING and SPREADING: the kind of opening made at the lips OPEN, CLOSE, and SEMI-OPEN vowels : how wide the mouth is opened in the production. LONG vowels and SHORT vowels: the length of the vowels

Broad Transcription and Narrow Transcription Broad Transcription: the use of simple set of symbols in the transcription Narrow Transcription: the use of more specific symbols in the transcription

Phoneme and allophones It is the smallest linguistic unit of sound that can signal a difference in meaning. English has approximately 45 phonemes Phonemes are transcribed using the normal set of phonetic symbols, but within ‘/ /’ instead of ‘[ ]’

Minimal pairs Pairs of words which differ from each other only by one sound e.g. chunk and junk fail and veil ban and bin fine and vine sink and zinc fan and van site and side bet and bat

Allophones - Aspirated [ph] and unaspirated [p=] are different phones and are variants of the phoneme /p/. Such variants of a phoneme are called ALLOPHONES. - The allophones are in COMPLEMENTARY DISTRIBUTION because they never occur in the same context.

Some Phonological rules /p/ →[p=] / [s] ________ [ph ] elsewhere /l/ → [l] / _________ V [l] / V ————

Assimilation Rules Nasalization Rule [- nasal] → [+ nasal] / —— [+ nasal] Dentalization Rule [- dental] → [+ dental] / —— [+ dental] Velarization Rule [- velar] → [+ velar] / ——— [+ velar] Devoicing Rule z → s / [- voiced, C] ________
