structure of speech sounds (articulation,
acoustics, perception)
Vocal organs
Segmentation of speech
Three classes: Consonants, Vowels, Glides
Description of consonants

Groups of sounds
Labial, Coronal, Dorsal
Sibilants/stridents: noisier fricatives and
affricates [s, z, , , , ]
Continuants: Fricatives, Vowels, Glides
t in atomic and atom
The alveolar t
the same sound in atomic and atom?
No
2
t in atom the tongue hits the alveolar ridge in a
ballistic motion; the closure cannot be
maintained for long
t in atomic the closure can be maintained at the
alveolar ridge
t in atom the tongue hits the alveolar ridge in a
ballistic motion; the closure cannot be
maintained for long
This sound is called flap
[ ]
(voiced)
pill and spill
The bilabial voiceless p
the same in pill and spill?
No
pill - an [h]-like sound after the release of [p]
spill – no such sound after the release of [p]
The [h]-like sound is called aspiration
Mechanism of aspiration

Time lag between the release of the stop closure
and the starting of vocal folds vibration

IPA symbol for aspiration: [ ]
Aspirated Unaspirated
pill [pl] spill [spl]
till [tl] still [st l]
kill [kl] skill [skl]
Vowels
Constriction/Sonority
Cons. Glides Vowels
most/least least/most
Syllabicity (occupying the syllable peak/nucleus)
Cons./Glides Vowels
least most
Vowel articulation
- The front and back of the tongue
- Lips
The front and back of the tongue
Two dimensions in movements
- raising/lowering (Pete-pit-pet-pat)

boot
- Spread (unrounded)
