Automatic speech recognition (ASR) is a very attractive means for human-machine
interaction. The degree of maturity reached by speech recognition technologies during …

This paper presents a mixed recovery scheme for robust distributed speech recognition
(DSR) implemented over a packet channel which suffers packet losses. The scheme …

In this paper, we present a family of compression methods based on differential vector
quantization (DVQ) for encoding Mel frequency cepstral coefficients (MFCC) in distributed …

We propose a novel packetization and variable bitrate compression scheme for DSR source
coding, based on the Group of Pictures concept from video coding. The proposed algorithm …

The transmission errors in a wireless or packet oriented network may dramatically decrease
the performance of a distributed speech recognition (DSR) system. Error concealment has …

In this paper, we propose a whole recovery scheme designed to improve robustness against
packet losses in distributed speech recognition systems. This scheme integrates two sender …

This paper presents a framework for the error concealment of multimedia signals transmitted
over wireless and IP networks. This framework is based on two elements. First, the …

In this work we evaluate the performance of MMSE estimation with a media-specific FEC
based on VQ replicas in comparison with MAP estimation and interleaving, both operating in …

In this work we present a complete set of techniques devoted to offer robustness against
frame losses in distributed speech recognition over packet-switched networks. The …

This paper presents a packet loss recovery method that uses an incomplete secondary
encoding based on scalar quantization as redundancy. The method is redundancy bit rate …
