I would like to know how can I conversion voic, not by voltage by
frequency.

What do you want to do exactly and for what use?

u have to first convert the analog signal from the microphone to digital
format.. u can do it using the on chip analog to digital converter.. then u
can send the digital data to some memory ... via spi or...twi(I2C)... mmc
and sdc use spi interface....

There isn't really enough info in that request to determine what he wants
to do. Saying "not by voltage by frequency" inplies doing an FFT
somewhere along the line.

As per my knowledge, there is no way to convert audio by frequency

There are various things that could be implemented by doing an FFT and
processing in the frequency domain, but I don't know if I'd want to try it
with an AVR. That's an awful lot of processing. Forget about real-time.

Maybe I'm wrong.

You could implement various FIR and IIR filters in the time domain and get
better results.
