Abstract

The presence of acoustic echo deteriorates the quality of speech transmission in mobile communication systems. In conventional acoustic echo suppression (AES) set-up, the echo path effect is modelled either in time domain or in frequency domain, and to cancel the echo, a replica of the echo is created by estimating the echo path response adaptively. Recently, the modulation domain analysis which captures the human perceptual properties is widely being used in speech processing. Modulation domain conveys the temporal variation of the acoustic magnitude spectra. In this work, a novel method for modelling the echo path and estimating the echo in modulation domain is developed and implemented. Echo cancellation is done effectively using the modulation spectral manipulation. So far, no work on echo suppression in modulation domain has been found as reported. The quality of output of the proposed system is found to be better than conventional AES systems.
