.wav speech file modulation with simulink model

Hello,

I would most appreciate it if I could get help on which block diagram I need after a .wav speech block for acheiving modulation and demodulation using ask or fsk.

After multiplying the output of the .wav file with a cosine carrier the output i get gives an error that says the input must be sample-based.I then used an unbuffer at the output of the .wav block before multiplying the cosine carrier,but i still do not get the expected output waveform.

please how do go about it,as any idea would be welcomed.

Thanks
yeks
