May be you want it like this (I've done this before playing around with Audacity recording software)

I sampled an audio info as "READ<pause> THIS<pause> COVER"

then I processed it in the software; removing the silence(pauses) and reconstructing the speech waveforms

and it resembles as a new information as "REDISCOVER"!

try it

you can also do the same using MATLAB simulink
goodluck

in simulink you do not write the code , just drag and drop the required box's and simulate it .

for ex there is icon for mic , spk , filter , etc.

thank you

Very nice method for Data hiding in speech

Hello,

Have u heard about Steganography. It is like Cryptography, which can be used to hide the data in Images, audio files, video files t, text files.
You can use that technique.

If you need more details, please mail me.
