AAC | ADPCM | Convolution | DAFx | FFT | IIR | Mixer | MP3 | MPEG | MPEG-4

i have a voice clip and i want to detect total silent intervals.I am so confused. I hope
you help me. For exmple i want to do like this:

[x,fs]=wavread('x.wav');

% i want to get any value in every second like average decibel
 
for (?????) % how can set the loop. I am so confused. 

   if ( average_power_in_second < 10 )
       fprintf('%d. Sec. is Silent',i);
   else
       fprintf('There is no silence');
   end

end

matlab results as an example if wav file is 4 second:

1. Sec is Silent
2. Sec there is no silence
3. Sec there is no silence
4. Sec is Silent

i am waiting your helps.

Best Regards...
