Now in a thoroughly updated second edition, Digital Speech covers all aspects of digital speech coding from an introduction to the background, sampling and analysis, quantization methods, and coders through to the recent research in areas such as voice activity detection and speech enhancement. This is the only book available on the market that covers all of these areas in a single text suitable for both a senior undergraduate looking to learn the basics and researchers and engineers in universities and industry keen to learn the latest developments.
Building on the success of the first edition Digital Speech offers extensive new, updated and revised material based upon the latest research. This Second Edition continues to provide the fundamental technical background required for low bit rate speech coding and the hottest developments in digital speech coding techniques that are applicable to evolving communication systems.
_ Features new chapters on Pitch Estimation and Voice-Unvoiced Classification of Speech, Harmonic Speech Coding and Multimode Speech Coding
_ Presents a comprehensively revised chapter entitled Analysis by Synthesis LPC Coding including specific examples of popular speech coders such as CELP (Code-Excited Linear Predictive) Coding
_ Contains an updated chapter on Efficient LPC Quantization Methods including MSVQ and anti-aliasing filtering
_ Discusses Voice Activity Detection (VAD) methods
_ Offers expanded coverage of speech enhancement techniques such as echo cancellation and noise suppression
