Phonology: pitch computation #1102

Open myrix opened 5 months ago

myrix commented 5 months ago

Phonology results should also include pitch, jitter and shimmer computations for each analyzed vowel sound interval, just as how they can be computed in Praat.

How vowel pitch can be computed in Praat, with e.g. 'Красный чум' sound and markup from /dictionary/3104/11/perspective/3104/12/view, красный_чум_КЛМ.zip:

  1. Open Praat, load sound and markup: image

  2. Select sound and markup together, View & Edit: image

  3. Select a vowel interval, image then menu Pitch -> Get pitch: image image

Jitter and shimmer can be computed via Pulses -> Voice report menu: image

As usual, we would need to look through Praat's source code.

Pitch functionality with normal precision is ready. Results for красный_чум_КЛМ.zip you can see here

Jitter, shimmer computation is reported in separate issue. Pitch computation is generally implemented. One more new issue is created for phonology optimization.
