Acoustics of Stops

Acoustic Properties of Stop Consonants

VOT voice onset time is.. The interval between the articulatory release of a stop and the onset of vocal chord vibrations.
CV Formant Transition The articulatory transition between a stop and a vowel in the process of shifting formants.
Why are vowels lengthened before voiced stops? So that vowel duration cues the voicing contrast for a post vocalic stop
Stops(other than in word initial) are Identified in sound spectrum by what? The 'Voice Bar' at the bottom which is the fundamental frequency of the phonation
What is the relation between the Place of Articulation and energy levels of a stop? Labials are low frequency, Alveolars are High energy, Velars are mid Energy ( as in vowel location in relation to F1)
4 major components of Stop Acoustics 1) Stop Gap, 2)Release Burst, 3) Formant Transitions 4) Stop voicing
how can VOT identify Stop location? The further foward in the vocal tract the stop is articulated, the longer the VOT
Formant Transition The time it takes to transition the formants from the positioning of one sound unit to another
Velar Pinch When followed by a vowell, the F2 & F3 are marked by an increased separation for Velar Stop
For Pre Vocalic Stops, Stop Voicing... 'F1 Cutback' F1 energy is delayed relative to the higher formant of the Voiceless Stop, the greater the delay, the more likely the stop is -VC
V [stop] (list features) V lengthened _[+stop-vc],
VCV (rapid vs rabid) Duration of stop gap shorter for stops-vc, strength of burst weaker for +vc, fundamental freq.lower for +vc,duration of preceding V longer for +vc
