hi, am modifying the ASC python code for keyword spotting. Am using dataset which is 1 sec long wav files whereas ASC dataset is 30sec long wav files. 

while doing spectrogram-feature extraction am getting value 0.

what is the frame length and hop length I need to give for 1sec long audio?

Also, whether I can use the same log mel feature extraction module for this?

Please help.

Hi @ShivaRagu​ 

I am not the owner of that script, but the purpose is to have 1024ms frame to be in the power of 2 (to ease computation). In the script, the frame length should be adapted to 1s to fit the dataset length. Where you able to solve you issue ?
