Model-based independent component analysis for robust multi-microphone automatic speech recognition

In this communication, we present a method for noise-robust multi-microphone automatic speech recognition (ASR). It is assumed that the speech source to be recognized is

Improving ASR performance on PDA by contamination of training data

Automatic Speech Recognition (ASR) on Personal Digital Assistant (PDA) suffers from the intrinsic hard­ware characteristics of the audio interface, for example, low quality microphones and

A study of implicit and explicit modeling of coarticulation and pronunciation variation

In this paper, we focus on the modeling of coarticulation and pronunciation variation in Automatic Speech Recognition systems (ASR). Most ASR systems explicitly describe these

Chirp group delay analysis of speech signals

This study proposes new group delay estimation techniques that can be used for analyzing resonance patterns of short-term discrete-time signals and more specifically speech signals.

Spectral analysis of speech signals using chirp group delay

This study presents chirp group delay processing techniques for spectral analysis of speech signals. It is known that group delay processing is potentially very useful
