For many decades, hybrid devices have been used to connect 2-wire local circuits and 4-wire long distance circuits in telephone lines. This leads to a weIl known problem, whereby echoes are generated. The delay introduced by telecommunication satelli

There is a need for echo cancelers for echo paths with long impulse responses (/spl ges/64 ms). This in turn creates a need for more rapidly converging algorithms in order to meet the specifications for network echo cancelers. Faster convergence, how

A modified Baum-Welch algorithm is developed and applied to estimating parameters of error source models that belong to the class of hidden Markov models (HMM). Such models arise in the description of bursty error statistics in communication channels

It is noted that of great importance to the success of the articulatory approach to speech coding is the use of a good distortion measure between a given speech signal and the entries in a stored codebook of impulse responses and corresponding vocal-

We discuss the philosophy of evaluating estimated impulse responses for applications in which the overall scaling or gain is irrelevant, as, for example, in blind channel identification. We argue that no matter how the estimate is obtained, the perfo

Recent progress in developing automatic articulatory analysis-synthesis procedures is described. The goal of the research is to find ways to fully exploit the advantages of articulatory modeling in producing natural-sounding speech from text and in l

Teleconferencing systems employ acoustic echo cancelers (AECs) to reduce echos that result from coupling between the loudspeaker and microphone. To enhance the sound realism, two-channel audio is necessary. However, in this case (stereophonic sound)

Echo cancelers which cover longer impulse responses (/spl ges/64 ms) are desirable. Long responses create a need for more rapidly converging algorithms in order to meet the specifications for network echo cancelers devised by the ITU (International T

A signal processor for the determination of respiration and heart rates in Doppler radar measurements is described. The processor can reliably calculate both rates for a subject at distances as large as 2 m. The rate determination is based on autocor
