Robust speech recognition of uncertain or missingdata: theory and applications

Automatic speech recognition suffers from a lack of robustness with respect to noise, reverberation and interfering speech. The growing field of speech recognition in the presence of missing or uncertain input data seeks to ameliorate those problems by using not only a preprocessed speech signal but also an estimate of its reliability to selectively focus on those segments and features that are most reliable for recognition. This book presents the state of the art in recognition in the presence of uncertainty, offering examples that utilize uncertainty information for noise robustness, reverberation robustness, simultaneous recognition of multiple speech signals, and audiovisual speech recognition. The book is appropriate for scientists and researchers in the field of speech recognition who will find an overview of the state of the art in robustspeech recognition, professionals working in speech recognition who will findstrategies for improving recognition results in various conditions of mismatch, and lecturers of advanced courses on speech processing or speech recognition who will find a reference and a comprehensive introduction to the field. Thebook assumes an understanding of the fundamentals of speech recognition usingHidden Markov Models. Scientists and researchers in the field of speech recognition will find anoverview of the state of the art in robust speech recognition. Professionals working in speech recognition will find strategies for improving results in various conditions of mismatch. The contributing authors are among the leading researchers in this field.
