This book focuses on speech processing in the presence of low-bit rate coding and varying background environments. The methods presented in the book exploit the speech events which are robust in noisy environments. Accurate estimation of these crucial events will be useful for carrying out various speech tasks such as speech recognition, speaker recognition and speech rate modification in mobile environments. The authors provide insights into designing and developing robust methods to process the speech in mobile environments. Covering temporal and spectral enhancement methods to minimize the effect of noise and examining methods and models on speech and speaker recognition applications in mobile environments.

From the book reviews:

“The authors provide comprehensive coverage of major speech processing techniques. … The book is written in simple English and is easy to read. Students and researchers working in speech processing will find it useful.” (S. Ramakrishnan, Computing Reviews, August, 2014)

“This book is based on Vuppala’s PhD thesis … . It is indeed a commendable exercise to place details of a research work before a wider audience. … Research scholars working in the domains of signal processing, speech, and speaker recognition systems will find this book very useful.” (C. K. Raju, Computing Reviews, May, 2014)
