Hi my friends
I am going to determine the fundamental frequency of a speech signal that it is digitized.I want to perform this by means of avr. Can anyone help me in sourse codes?
thanks from all

Hi

In order to analyse digitized speech signal you will need to do FFT analyse of the signal data

The AVR micro controller (8 bit) is to week to preform a good work I suggest you to work with more advanced micro like AVR32 or ARM cortex

All the best
