Describing Speech Sounds

• Is the air-flow blocked?vowel vs. consonant

• What are the vocal folds doing? (=voicing)voiced vs. voiceless

• Where is the air-flow blocked? (=place)labial, alveolar, palatal, velar etc., , p ,

• Where/how is the air flowing? (=manner)nasal/oral, stop, fricative, liquid etc., p, f , q

Consonants

• produced by closure/constriction of the vocal tract

Manner

• Stops: complete stoppage of air

[p] [b] [t] [d] [k] [g][p] [b] [t] [d] [k] [g]...

• Fricatives : airflow is severely obstructed causing friction causing friction [f] [v] [θ] [∂] [s] [z] [Ω] [ß] [h] []

Fricatives & Affricates

• Palatal sounds [ʒ] [ʃ] [tß] [dΩ]• Palatal Fricatives [ʒ] [ʃ]• Palatal Fricatives - [ʒ] [ʃ]

[note: according to IPA chart these are strictly ‘post-alveolar’]]

• Affricates - combination of stop + fricative - [tß] [dΩ] as in judge churchfricative - [tß] [dΩ] as in judge, church

Liquids, glides

• Liquids[l][r][ ][ ]– Lateral [l] : air escapes along sides of tongue

– Retroflex [r]: tongue is bunched upward and Retroflex [r]: tongue is bunched upward and back in mouth

• Glides: semi-vowels semi-consonants Glides: semi vowels, semi consonants [w] [j]

nasal

• Nasal: velum is lowered, and air flows through nasal cavityg y[m] [n] [˜]

Putting them all together Putting them all together… “Voicing, Place, Manner”

• how do we describe [p]?

Voiceless bilabial stopVoiceless, bilabial stop

Wh b [b]?What about [b]?

Features

• Ways of describing soundse.g., [p] = voiceless bilabial stopg , [p] p

• Stronger claim: features are the smallest building blocks of language used to store building blocks of language, used to store sounds in the mind

• Atoms of Speech• Atoms of Speech

Features

• Prediction: by combining a small number of atomic features, it should be possible to create a larger number of speech soundslarger number of speech sounds

• Goal: a set of universal features should make it • Goal: a set of universal features should make it possible to describe the speech sounds of all of the languages of the world

• Different languages choose different feature combinations

Sounds from other languages

• From Spanish: [ɲ] as in año ‘year’

–voiced, palatal, nasalvoiced, palatal, nasal

• From German: [X] as in Bach• From German: [X] as in Bach–voiceless, velar, fricative

• Other languages?

Spanish: año
