Speech Acoustics 7 - voice onset time (VOT)

A video about voice onset time - the acoustic property that distinguishes voicing in stop consonants. For example, the differences between b-p, d-t and g-k

This is outstanding. Just as a suggestion, it would have been interesting to hear the original sounds depicted in your graphics.

I'm writing a paper about VOT and this is SO helpful. Thank you so much!

Soo helpful thank you! The highlighting and clear boundaries on the waveforms were great.

In the beginning of a syllable, the English b is not a voiced consonant. It is just unaspirated and unvoiced.
Comparing to French, if you cut off the "s" part of "star", it sounds exactly like "tar" (for example the word "tard" with slient d), and it is different than "dar" (for example the word "dard" with a silent d)

There are languages that do three way (even four) distinctions, for instance Southern Min has 3 and Hindi has 4.
Unvoiced Aspirated for VOT ~= 50 ms
Unvoiced Unaspirated for VOT ~= 0 ms
Voiced Unaspirated for VOT ~= -50 ms
Voiced Aspirated for VOT ~= -50 ms (with beginning breathy voice)

I wonder if you show me how to do with annotation and segmentation of stops both plain and labialized in the context of initial and intervocalic positions.

شكراthank you, so much. That was helpful.

Can anyone tell, why we are learning it? I meant the objectives or implications?
