Produktinformationen zu „Techniques for Noise Robustness in Automatic Speech Recognition (PDF)“
Automatic speech recognition (ASR) systems are finding
increasing use in everyday life. Many of the commonplace
environments where the systems are used are noisy, for example
users calling up a voice search system from a busy cafeteria or a
street. This can result in degraded speech recordings and adversely
affect the performance of speech recognition systems. As the
use of ASR systems increases, knowledge of the state-of-the-art in
techniques to deal with such problems becomes critical to system
and application engineers and researchers who work with or on ASR
technologies. This book presents a comprehensive survey of the
state-of-the-art in techniques used to improve the robustness of
speech recognition systems to these degrading external
influences.
Key features:
* Reviews all the main noise robust ASR approaches, including
signal separation, voice activity detection, robust feature
extraction, model compensation and adaptation, missing data
techniques and recognition of reverberant speech.
* Acts as a timely exposition of the topic in light of more
widespread use in the future of ASR technology in challenging
environments.
* Addresses robustness issues and signal degradation which are
both key requirements for practitioners of ASR.
* Includes contributions from top ASR researchers from leading
research units in the field

Autoren-Porträt
Tuomas Virtanen, Tampere University of Technology, FinlandDr . Virtanen is a senior researcher at Tampere University of Technology. Previously, he has worked at Cambridge University, UK as a research associate. His main research contributions are in sound source separation and its application to robust speech recognition, audio content analysis, and music information retrieval. He is well-known for his work on non-negative matrix factorization based source separation, which is currently widely used in the field. He has published numerous journal and conference articles related to above topics.
Rita Singh, Carnegie Mellon University, USA
Dr. Singh is the CEO of a speech-technology startup but remains an adjunct faculty of the Language Technologies Institute at Carnegie Mellon University. She has been a major contributor to the open-source CMU sphinx and is one of the main architects of the popular Sphinx4 java-based open-source speech recognition system. In addition to her work on core speech recognition technology, she has also developed several algorithms for noise compensation, and was the prime architect of CMU's award-winning submission to the 2001 Naval Research Lab's challenge on automatic recognition of speech in noisy environments (SPINE).
Bhiksha Raj, Carnegie Mellon University, USA
Dr. Raj is an associate professor in the Language Technologies Institute and in Electrical and Computer Engineering at Carnegie Mellon University. He has worked extensively on robustness algorithms for speech recognition, and is very well-known for his contributions to the highly-popular VTS approach for noise compensation, as well as his contributions to missing-feature-based techniques for noise compensation. He has published extensively on and holds patents for algorithms for microphone array processing and signal separation.
