Vocal Accoustics - What to consider when comparing with other vocal features extracted outside of openwillis

[valericac]

I am looking to extract several vocal features beyond the ones currently provided, based on the current literature on PTSD. To ensure consistency and comparability in feature extraction, I would like to better understand the pre-processing steps you apply. Specifically, I am interested in how I can apply the same processing for extracting features outside the current vocal acoustics set. While I have already cleaned the audio, I want to ensure there are no additional considerations I should be aware of when merging the features. Otherwise I think I can use the framewise output directly and apply my analysis to it.

We are currently not applying any preprocessing on the audio signal directly, so you should be set to compare/combine the features extracted with other libraries.

In terms of using the framewise output directly you can certainly do so. Each frame is computed in a window of 10ms, so there are 100 frames in each second, regardless of audio FPS. For your information only a subset of the vocal acoustics measures we compute are done so at the frame level.
