Hi all,
In aishell TDNN training, why pitch features are not given for i vector extraction?

it reduces latency to not use pitch, so it's easier to use in real-time applications; and if you use high-frequency-resolution features (like 80-dim MFCCs) the added benefit of pitch is not that great anyway.

I don't recommend using pitch for speaker verification.
