Developing a successful multi-microphone speech acquisition system in a reverberant, cocktail-party-like environment is a very challenging problem since both interfering sources and reverberation n

Speech Analysis and Synthesis Using a Vocal Tract/Cord Model -- We are considering the use of our vocal cord and tract model [Schroeter and Sondhi, J. Acoust. Soc. Am. Suppl.

In this paper, the AM-FM modulation model is applied to speech analysis, synthesis and coding.

Transmission advances over the next few years will provide pervasive switched digital capacity.

Transmission advances over the next few years will provide pervasive switched digital capacity.

The subject of speech coding covers speech processing techniques for reducing the information rate to transmit a speech signal over a communication channel.

In coding systems based on the excitation- and -LPC model for speech, parameters of the two parts of the model are separately quantized, with levels of fidelity that are constrained by the total bi

Over the recent year, considerable progress has been achieved in producing high quality digitally-encoded speech at low bit rates.

Encryption can be an important requirement in speech communication systems.

A maximum a-posteriori approach for enhancing speech signals which have been degraded by statistically independent additive noise is proposed.
