Hello, all. As a part of my project, I need to use Matlab for voice/unvoice separation of the recorded speech file.For now I can record a file in Matlab, and calculate Zerro-Crossing Rate(ZCR). But afterward I need to calculate the frame energy of a signal.Please help me to calculate frame energy. Please assist.
Thank you in advance. --------- Rahiba

I have very useful this code to understand the frame energy.But I can't set the threshold for classifying the speech sound and silence by using frame energy and zero crossing rate. sir please help me to set the threshold.
