This book offers an overview of audio processing including the latest advances in the
methodologies used in audio processing and speech recognition. First it discusses the
importance of audio indexing and classical information retrieval problem and presents two major
indexing techniques namely Large Vocabulary Continuous Speech Recognition (LVCSR) and Phonetic
Search. It then offers brief insights into the human speech production system and its modeling
which are required to produce artificial speech. It also discusses various components of an
automatic speech recognition (ASR) system. Describing the chronological developments in ASR
systems and briefly examining the statistical models used in ASR as well as the related
mathematical deductions the book summarizes a number of state-of-the-art classification
techniques and their application in audio speech classification. By providing insights into
various aspects of audio speech processing and speech recognition this book appeals a wide
audience from researchers and postgraduate students to those new to the field.
