Abstract:

We propose an analog transmission of a speech cepstrum for the dual purposes of bandwidth reduction and improvements in speech quality under extremely challenging channel environments. By utilizing the speech cepstrum, we exploit a well-studied and widely-used sparse representation of speech. The novelty in the method is that we propose to f?ospreadf?? the waveform defined by the first few cepstral coefficients over the speech frame length, i.e. time-domain spreading. This spread cepstrum approach reduces the bandwidth and may offer robustness to noise for low-power applications.
