    A high-quality introduction

    I purchased this book four months ago and so far I found it to be well-organized and current. The author stresses the algorithmic details of production coders (or standardized coders), adding a refreshing realism to the book. The book emphasizes on implementation, with no lack on the theoretical aspects, where thorough mathematical proofs are included. Its extensive set of references serves as a roadmap through the literature and allows the reader to follow developments in the field over time. I would like to see the author to incorporate more recent standards (such as AMR-WB and SMV) in future revisions; however, the present version is excellent and the intended audience, graduate students and researchers, will find the book to be a high-quality introduction to speech coding.
