fft and pitch

Started by nmoff2003 March 16, 2004
hi,

I am using the fft to get pitch. i have a speech sample which i
have divided into frames. i ckeck if the frame is voiced or
unvoiced by geting the energy and if is voiced i get its fft.

i then get the magnitude of it.

the magnitude shows peaks at multiples of the fundamental
frequency.

is the pitch period the distance between F2 and F1.

when you have the pitch period how do you get the pitch from that to
plot the pitch contour for all frames.

i am doing this in both matlab and C.

if anyone has any information could you please help me

thanks
