most common VOIP echo simulaton for research purposes ?
Hi,
I'm speech recognition researcher and would like to do some research on
recognition robustness in echo distortion of speech signal. Since VOIP is
becoming wide spread, I'd like to simulate (one or more) common echo
distortions that mostly appear in voip communications ? Any example, FIR or
IIR filter or acoustical system response ?
Any other distortion worth researching ?
Thanks
