The book reflects the state of the art in important areas of speech and audiosignal processing. It presents topics which are missed so far and most recentfindings in the field. Leading international experts report on their field ofwork and their new results. Considerable amount of space is covered by multi-microphone systems, specific approaches for noise reduction, and evaluations of speech signals and speech processing systems. Multi-microphone systems include automatic calibration of microphones, localisation of sound sources, and source separation procedures. Also covered are recent approaches to the problem of adaptive echo and noise suppression. A novel solution allows the design of filter banks exhibiting bands spaced according to the Bark scale und especially short delay times. Furthermore, a method for engine noise reduction and proposals for improving the signal/noise ratio based on partial signal reconstruction or using a noise reference are reported. Topics are presented missed so far in literature as well as recent scientific breakthroughs Written by an international team of excellent researches INDICE: TRINICON-based Blind System Identification for Source Localizationin Reverberant Environments.- Microphone Calibration for Multi-Channel SignalProcessing.- Sound Control Algorithms in Automobiles.- Evaluation of Hands-free Terminals.- Joint Dereverberation and Acoustic Echo Cancellation in a NoisyEnvironment.- Speech Quality in Communication Systems.- Nonlinear Echo Cancellation Based on Spectral Shaping.- Bandwidth Extension of Telephony Speech.- Model-Based Speech Enhancement.- Low Delay Filter-Banks for Speech Processing.-A Pre-Filter for Hands-Free Car Phone Noise Reduction: Suppression of Harmonic Engine Noise Components.- Binaural Sound Segregation.- Correlation-Based TDOA-Estimation for Multiple Speech Sources.- Towards Robust Automatic Speech Recognition (ASR) in Reverberant Environments.- Spatio-Temporal Adaptive Filtering in the Wave Domain.- Low Distortion Noise Cancellation – Revival of a Classical Technique.- Virtual Hearing: A Hearing Simulation Package for Hearing Aid Design.
