A Practical Handbook of Speech Coders
A Practical Handbook of Speech Coders offers in-depth treatment of the basics of speech coding plus the innovations to the basic methods that make the coders useful and efficient. It describes the fundamentals of auditory information processing and how they relate to speech coding, and shows readers how to evaluate the strengths and weaknesses of all publicly available codes and choose the right one. It explains how to measure the quality of speech coders with objective, subjective, and perceptual measures. The book also shows engineers how to tailor existing speech coders and provides the building blocks to create new coders.
A Practical Handbook of Speech Coders
The demand for digital speech coding algorithms grows every day, fueled by applications such as streaming speech over the Internet, Internet telephone, digital cellular telephony, wireless teleconferencing, and various multimedia applications. Until now, most of the books available on audio coding have been collections of individually authored papers. Others have discussed the fundamental coders, but neglected many of the innovations currently in use. Unlike these books, A Practical Handbook of Speech Coders offers in-depth treatment of the basics of speech coding plus the innovations to the basic methods that make the coders useful and efficient. The authors designed this work for engineers, scientists, and manager who need to understand the emerging speech coding techniques and telecommunication standards. However, it will prove useful to people at all levels of speech coder experience: If you want to simply download the code for an existing algorithm, this book helps you evaluate the strengths and weaknesses of all publicly available codes and choose the right one, then points you to the Internet location where the code is available for download. For experts who want to improve on existing coders, this book provides the parameters of current coders and the techniques to improve upon them. You can download an existing algorithm or code it using the algorithmic descriptions in the book, make your innovations, and then test the code with the procedures given. If you want to become an expert and have some basic knowledge of digital signal processing, you can learn the innovative steps taken by the inventor of each coder, explore the rigorous research techniques needed to develop your own coder, and become proficient in existing vocoder technology.
Speech Coding Algorithms
Speech coding is a highly mature branch of signal processing deployed in products such as cellular phones, communication devices, and more recently, voice over internet protocol This book collects many of the techniques used in speech coding and presents them in an accessible fashion Emphasizes the foundation and evolution of standardized speech coders, covering standards from 1984 to the present The theory behind the applications is thoroughly analyzed and proved
