i am doing a project with microphone array in matlab.i need to find th
frequency of the voice signal which is received through the mic.

can any one help me out ...........

What is the sample rate of the ADC?

Perform FFT of signal and you can find out the frequency content.

Hi,

Since you say "_the_ frequency of...", I assume you mean the
fundamental frequency, otherwise you would use the plural.

You need to do pitch-tracking. The first peak in an autocorrelation
can tell you the fundamental frequency. This is a standard method.

Since you are specifically interessted in voice-signals, there might
be others methods which are optimal for that purpose, which are
based on the fact that typical speech-signals have common shapes.
