 Section.I analyzes some successful applications of the audio and speech signal processing technology, specifically in applications regarding the audio effects, audio synthesis, and restoration. This section consists of three chapters, which are described in the following paragraphs.Section. II provides an analysis of recently developed speech and audio watermarking methods. The advance in the digital technology allows an error free copy of any digital material, allowing the unauthorized copying, distribution, and commercialization of copyrighted digital audio, images, and videos. This section, consisting of two chapters, provides an analysis of the watermarking techniques that appear to be an attractive alternative to solving this problem. Section.III..The adaptive filtering has been successfully used in the solution of an important amount of practical problems such as echo and noise canceling, active noise canceling, speech enhancement, adaptive pulse modulation coding, spectrum estimation, channel equalization, and so forth. Section III provides a review of some successful adaptive filter algorithms, together with two of the must successful applications of this technology such as the echo and active noise cancellers. Section III consists of four chapters, which are described in the following paragraphs. Section.IV..The speech recognition has been a topic of active research during the last 30 years. During this time a large number of efficient algorithms have been proposed, using hidden Markov models, neural networks, and Gaussian mixtures models, among other several paradigms to perform the recognition tasks. To perform an accurate recognition task, besides the paradigm used in the recognition stage, the feature extraction has also great importance. A related problem that has also received great attention is the speaker recognition, where the task is to determine the speaker identity, or verify if the speaker is who she/he claims to be. This section provides a review of some of the most widely used feature extraction algorithms. This section consists of four chapters that re described in the following paragraphs.
