Hi all. I have speech signal, and I divided it into frames with 150 samples. How can I calculate the energy of each frame? I'm trying to decide which frame is voiced or unvoiced. by looking their energy.

You could take the rms value of all columns of x. After that, define your own threshold to determine what is speech and what isn't.
x_rms = rms(x,1); % this gives a row with the root mean square values of the collumns/frames.
Kind regards, Baltam
