Издательство Idea Group, 2007, -465 pp.Speech is no doubt the most essential medium of human interaction. By means of modern digital signal processing, we can interact, not only with others, but also with machines. The importance of speech/audio signal processing lies in preserving and improving the quality of speech/audio signals. These signals are treated in a digital representation where various advanced digital-signal-processing schemes can be carried out adaptively to enhance the quality. Here, special care should be paid to defining the goal of quality. In its simplest form, signal quality can be measured in terms of signal distortion (distance between signals). However, more sophisticated measures such as perceptual quality (the distance between human perceptual representations), or even service quality (the distance between human user experiences), should be carefully chosen and utilized according to applications, the environment, and user preferences. Only with proper measures can we extract the best performance from signal processing. Thanks to recent advances in signal processing theory, together with advances in signal processing devices, the applications of audio/speech signal processing have become ubiquitous over the last decade. This book covers various aspects of recent advances in speech/audio signal processing technologies, such as audio signal enhancement, speech and speaker recognition, adaptive filters, active noise canceling, echo canceling, audio quality evaluation, audio and speech watermarking, digital filters for audio effects, and speech technologies for language therapy.Introduction to Audio and Speech Signal Processing Audio and Speech Signal Processing Technology Digital Filters for Digital Audio Effects Spectral-Based Analysis and Synthesis of Audio Signals DSP Techniques for Sound Enhancement of Old Recordings Speech and Audio Watermarking Methods Digital Watermarking Techniques for Audio and Speech Signals Audio and Speech Watermarking and Quality Evaluation Adaptive Filter Algorithms Adaptive Filters: Structures, Algorithms, and Applications Adaptive Digital Filtering and Its Algorithms for Acoustic Active Noise Canceling: Structures and Adaption Algorithms Differentially Fed Artificial Neural Networks for Speech Signal Prediction Feature Extraction Algorithms and Speech Speaker Recognition Introduction to Speech Recognition Advanced Techniques in Speech Recognition Speaker Recognition Speech Technologies for Language Therapy
