exampleupper articulator

lower articulator

Manner of articulation (degree of occlusion)

• How close are lower and upper articulator?–Relatively close, narrowed or

constricted (‘occluded’) airflow: consonants

–Relatively far apart, unconstrictedairflow: vowels

Manner of articulation

• Consonant subclasses–Stops: complete occlusion of airflow

–bill, dill, gill–Fricatives: air pressure build-up

behind occlusion; turbulent airflow–Liquids and glides: no pressure

build-up

English fricatives

Fricative: produced with turbulent airflow, pressure build-up behind occlusion

Clip from The Human Language vol. 3: The Human Language Evolves. “With and without words”

States of the glottis in English• voiced: vocal cords close, vibrate when air

passes through glottis• voiceless: vocal cords apart, do not vibrate• Some voiced and voiceless fricatives

Other consonant parameters:oral vs. nasal

Oral vs. nasal

• Velum raised– Air flows into oral cavity only

oral sound• Velum lowered (resting position)

– Air flows into oral and nasal cavitiesnasal sound

English oral vs. nasal stops

Stop: produced with complete occlusion in oral cavity

nasal (stop)(oral) stop

Other consonant parameters: lateral

•What part of the tongue (lower articulator) approaches the upper articulator?

•Only tip: air flows around side(s) of tongue (‘lateral’)

•Air flows over all tongue surface (‘central’)

•English: lip (lateral) vs. rip (central)

Phonetic description

• Consonants–State of glottis voiceless–Place of articulation bilabial–Manner of articulation stop

Phonetic transcription

• Alphabetic and other symbols which abbreviate phonetic descriptions– E.g. voiceless bilabial stop = [p]

• Phonetic transcription in square brackets• Different systems of phonetic transcription

– International Phonetic Association– ‘Americanist’/U.S.

Phonetic transcription

• A more consistent way of representing sound than most writing systems–e.g. English <c>: [k] [kræbi] <crabby>

[s] [pnsl ] <pencil>• A universal framework for the

description of spoken languages• Many languages lack writing systems

Some Witsuwit’en soundsEjective stops and affricates: transcribed [C’]

How to make a (canonical) ejective:

0. Make a velar stop.

Make a glottal stop.

Ejective stops• [t’] = ejective alveolar stop

– [nt’q] ‘your collarbone’• Compare [t] = voiceless alveolar stop

– [ntq] ‘up’• Waveforms:

Uvular place of articulation•[q] = voiceless uvular stop

–[qis] ‘Chinook salmon’–[ntq] ‘up’

•[q’] = voiceless uvular ejective

–[q’] ‘backwards’•[] = voiceless uvular fricative

–[] ‘grease’

Lateral fricative and affricates

• [] = voiceless lateral fricative– [jl] ‘it’s white; goat’– [aqh] ‘dogs’

• [t] = voiceless lateral affricate– [stet] ‘it’s licking me’

• [t’] = ejective lateral affricate– [st’et] ‘he farted’

Summary• Describing consonants

–place of articulation–manner of articulation (degree of

occlusion)–state of glottis–nasal/oral– lateral/central

• Phonetic transcription• Consonant charts

Question

• Describe one of the consonants you know (in one of the languages you know) that is different from one of the consonants of English. Be sure to name the language.
