Phonetics

Definition

• Examining the inventory and structure of the sounds of language (O’Grady and Dobrovolsky:1989)

• Phonetics first of all divides, or segments, concrete utterances into individual speech sounds. It is therefore exclusively concerned with parole or performance. Phonetics can then be divided into three distinct phases: (1) articulatory phonetics, (2) acoustic phonetics, and (3) auditory phonetics. (Skandera & Burleigh:2005)

• Phonetics is essentially the study of the physical aspects of speech. This means the physiological bases of speech.

• Thus, phonetics research might investigate the collection of frequencies of sounds observed in the production of particular types of vowels, or it might examine the precise movements of the tongue in producing the sound 's', for example

1. Anatomy of Vocal Organs

2. Air-stream Mechanisms

1. Pulmonic2. Glottic3. Velaric

A. Pulmonic Sounds

• Air flow is directed outwards towards the oral cavity• Pressure built by compression of lungs English: [p], [n], [s], [l], [e]

B. Glottic Egressive Sounds

• Air flow is directed outwards towards the oral cavity• Pressure built by pushing up closed glottis• Georgian [p’], [t’], [k’]

Glottic Ingressive Sounds

• Air flow is directed inwards from the oral Cavity• Pressure reduced by pulling down closed glottis

C. Velaric Sounds

• Air flow is directed inwards from the oral cavity• Pressure reduced by forming velaric and alveolar closure and pulling down tongue

Articulation

• Manners of Articulation• Places of Articulation

Places of Articulation

Places of Articulation (2)

• Place of articulation : Each point at which the airstream can be modified to produce a different sound.

• Places of articulation are found at the lips , within the oral cavity, in the pharynx, and at the glottis.

Places of Articulation : Labial

Labial: any sound made with closure or near closure of the lips • Bilabial: sounds involving both lips English: peer, bin, month• Labiodental: sounds involving the lower lip

and upper teeth English: fire, vow

Places of Articulation : Dental

Dental: Some phones are produced with the tongue placed against or near the teeth • Interdental: if the tongue is placed between

the teeth English: this, thing Note: some English speakers produce s and z

as dentals)

Places of Articulation : Alveolar

Alveolar ridge: within the oral cavity, a small ridge protrudes from just behind the upper front teeth• English: top, deer, soap, zip, lip, neck

Places of Articulation : Alveopalatal &Palatal

• Alveopalatal/palatoalveolar: just behind the alveolar ridge, the roof of the mouth rises sharply

English: show, measure, chip, judge• Palate: the highest part of the roof of the

mouth • Palatal: Sounds produced with the tongue near

the area English: yes

Places of Articulation : Velar

• Velar: the soft area toward the rear oof the roof of the mouth.

• Velum: Sounds made with the tongue in the position

English: call, guy, hang• Labiovelar: the tongue is raised near the

velum and lips are rounded at the same time English: wet

Places of Articulation : Glottal

• Glottal: Sound produced by adjusting the glottal opening to states other than voicing or voicelessness .

English: heave, hog

SOUND CLASSES

Vowels Consonants

Are produced with relatively little obstruction in the vocal tract

Are produced with a narrow or complete closure in the vocal tract

Are more sonorous Are less sonorous

Are syllabic Are generally not syllabic

Manners of Articulation

• Oral Vs Nasal• Stops• Fricatives• Affricatives• Liquids• American Glides

Manners of Articulation: Oral Vs Nasal

• Oral sounds are produced with air flowing through only the mouth

• The velum can be lowered to allow air to pass through the nasal passages, producing a sound that is nasal.

Manners of Articulation: Stops

• Stops are made with a complete and momentary closure of airflow through the oral cavity.• Stops are found at bilabial, dental,

alveolar, palatal, velar, uvular, and glottal points of articulation.

Point of articulation Transcription

Bilabial Voiceless span [p]

Voiced ban [b]

Nasal man [m]

Alveolar Voiceless stun [t]

Voiced dot [d]

Nasal not [n]

Velar Voiceless scar [c]

Voiced gap [g]

Nasal wing [ŋ]

Manners of Articulation: Fricatives

• Consonants produced with a continuous airflow through the mouth

• The air used in their production passes through a very narrow opening, resulting in turbulence, which causes the noise.

Point of articulation Glottal State Transcription

Labiodental Voiceless fan [f]

Voiced van [v]

Interdental Voiceless thin [θ]

Voiced then[ð]

Alveolar Voiceless sun [s]

Voiced zip [z]

Alveopalatal Voiceless ship [š]

Voiced azure [ž]

Glottal Voiceless hat [h]

Manners of Articulation: Liquids

• Among the sounds commonly found in the world’s language are l and r and their numerous variants. They form a special class of consonants knows as liquids.

• Laterals: varieties of l , voiced: [l], voiceless [ļ]: please, clear• English r’s: varieties of r. • Retroflex r : curling the tongue tip back into the mouth (US

and Canada): ride, car• Flap [D]: the tongue tip strikes the alveolar ridge as it passes

across it. bitter , butter , very (North American English)

Manners of Articulation: American Glides

• The two glides of English are [y] of yes and boy, and the w-glide [w] of wet and now.

Manners of Articulation (Consonants)

Consonants

Vowel – Features

• Low / High• Back / Front• Round• Nasal• Long

Vowel – Minimal Pairs

• Bag Big (English) /bæg/ /bɪg/• Beat bit /bit/ /bɪt/• Boot bait• /but/ /bet/

Diphthongs

• Combination of two vocalic sounds English: [aj] I, eye [aj] [aw] cow [kaw]

Gemination of Consonants

• Double/long consonants English: “misspell”, “unknown”

Phonology

Definition

Phonology is the study of the sounds used in languages: the way they pattern with respect to each other, the way they are use to make up words and phrases, and the changes they undergo (Andrew Spencer)

Phonology deals with the speakers' knowledge of the sound system of a language. It is therefore exclusively concerned with langue or competence, (Phonology, then, is not the study of telephone manners, as one student once jokingly suggested.) Phonology can be divided into two branches: (1) segmental phonology and (2) suprasegmental phonology.

Study of how sounds interact in various languages• Segmental phenomena• Phonemic Inventory and Allophony• Sound-change rules and ordering• Supra-segmental phenomena• Syllabification• Prominence• Tones• Intonation

• Mental concept representing a physical sound• Many to many mapping between phoneme and a phone within a language English /t/• aspirated in “tunafish”• unaspirated in “starfish”• dental before labio-dental• flapped in “buttercup”

• Phoneme = set of features that are true at a given time for a

• Particular phonemic unit (phonological features) (Autosegmental theory)

Phonological Rules

• Humans are lazy so compromise articulation to reduce effort• Compromise in Articulation changes the sound• Constituents of a phonological rules are• Phonemes to be modified due to a rule• Conditioning context in which the rule has to be fired• Change that occurs in a sound after the rule has been

fired• Rules are sometimes ordered in a language

Types of Phonological Rules

• Assimilation Addition of features due to neighboring phonemes phone book /fonbuk/ [fombuk] n [+bilabial] / __ [+bilabial, +voiced, +stop]• Dissimilation• Deletion of features due to neighboring

phonemes fifths /fIfth/ /fifts/

• Insertion / Deletion Addition or deletion of an entire phone• MetathesisChange order of phonemes prescribe => perscribe ask => aks

Syllable

A syllable is a unit of sound composed ofa central peak of sonority (usually a vowel), andconsonants that cluster around this central peak

Prominence

• Syllable(s) in a word may be more prominent than others

• Prominence can change meaning Spanish: término, 'end' (noun), termíno, 'I'm finishing' terminó, 'she/he finished’• English ‘ob.ject, ob.’ject ‘con.tent, con.’tent

Intonation

Intonation carries linguistic meaning, e.g. emotion, intention, etc.• You are going!• You are going.• You are going?
