week 1 Flashcards
Egressive pulmonic airflow
the normal mechanism for producing speech sounds in all languages.
four states of the glottis
voiced
voiceless
murmur
creaky voice
what is a nasal stop
soft palate lowered so that air flows out through the nose- complete closure of two articulators
eg. m, n
what is an oral stop
soft palate raised, forming velic closure. complete closure of two articulators.
eg. p, b , t
what is a fricative
narrowing of two articulators so as to produce a turbulent air stream
eg. f, v, th
what is an approximant
approximation of the two articulators without producing a turbulent airstream.
eg. w, j, l
what is a trill
articulator set in vibration by the airstream
eg. r, R
what is a flap
one articulator striking another in passing
eg. ɽ
what is a lateral
with a central obstruction so that air passes out the side
eg. ɮ, ʎ
what is a central
articulated so that air passes out the centre
eg. s, ɹ
what is a periodic sound
Periodic sound- each vibration is the same, it takes the same amount of time to reach from crest to peak.
McGurk effect
The McGurk effect is a perceptual phenomenon that demonstrates an interaction between hearing and vision in speech perception.
The illusion occurs when the auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound.
The perception of speech and sound is multi-modal.

4 Perceptual Categories
- Pitch
- Loudness
- Quality
- Duration
SUBJECTIVE NOT OBJECTIVE
