Day 4: Voice Activity Detection with Python - DEV Community
WebMay 23, 2015 · My first approach was implementing simple VAD (voice activity detector) using ZCR (zero crossing rate) & calculating Energy, but both of these paramters confuse DTMF, Dialtones with Voice. This techquie failed so I implemented a trivial method to calculate variance of FFT inbetween 200Hz and 300Hz.
