ABSTRACT:
A synthesized alternative sensor signal is produced from an alternative sensor signal. The synthesized alternative sensor signal is computed using vocal tract resonances estimated based on the alternative sensor signal, and using a waveform synthesis technique that converts the estimated vocal tract resonance sequence into a spectral magnitude sequence. The synthesized alternative sensor signal and the alternative sensor signal are used to estimate a clean speech value.
