Download or read book Acoustical and Environmental Robustness in Automatic Speech Recognition written by Alex Acero and published by Springer Science & Business Media. This book was released on 1992-11-30 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for automatic speech recognition systems to be robust with respect to changes in their acoustical environment has become more widely appreciated in recent years, as more systems are finding their way into practical applications. Although the issue of environmental robustness has received only a small fraction of the attention devoted to speaker independence, even speech recognition systems that are designed to be speaker independent frequently perform very poorly when they are tested using a different type of microphone or acoustical environment from the one with which they were trained. The use of microphones other than a "close talking" headset also tends to severely degrade speech recognition -performance. Even in relatively quiet office environments, speech is degraded by additive noise from fans, slamming doors, and other conversations, as well as by the effects of unknown linear filtering arising reverberation from surface reflections in a room, or spectral shaping by microphones or the vocal tracts of individual speakers. Speech-recognition systems designed for long-distance telephone lines, or applications deployed in more adverse acoustical environments such as motor vehicles, factory floors, oroutdoors demand far greaterdegrees ofenvironmental robustness. There are several different ways of building acoustical robustness into speech recognition systems. Arrays of microphones can be used to develop a directionally-sensitive system that resists intelference from competing talkers and other noise sources that are spatially separated from the source of the desired speech signal.

Download or read book Phase-based Speech Processing written by Guangji Shi and published by . This book was released on 2006 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of automatic speech recognition (ASR) systems degrades significantly in adverse environments due to ambient noise and reverberation. This problem becomes even greater in hands-free speech applications, where the microphones can be placed far away from the speaker of interest. Environmental robustness has become a major barrier that prevents ASR from a wide range of applications such as voice recognition in a car and voice controlled hand-held devices. In this research, the importance of phase in robust speech recognition is explored. First, the effect of phase uncertainty on the recognition accuracy of human listeners is investigated. The goal is to get a quantitative measure on the importance of phase. The results show that the importance of phase varies with SNR (signal-to-noise ratio). At low SNR conditions, phase can have a significant impact on speech recognition accuracy. Next, motivated by the importance of phase in multi-microphone signal processing, a phase-based dual-microphone noise masking approach is proposed for speech enhancement. By utilizing the time delay of the speech source of interest to the two microphones and the actual phases of the signals recorded by both microphones, the algorithm filters the noise signal in the short-time Fourier transform domain. By doing so, the noise components are distorted beyond recognition and the speech recognition accuracy is improved. The effectiveness of this approach is demonstrated through performance comparison with alternative techniques. Lastly, an automatic parameter estimation technique is developed to further optimize its performance. The parameter of the phase-based dual-microphone filter is adjusted in run-time automatically by performing likelihood calculations of the enhanced speech features using a prior speech model. Speech recognition tests show that this adaptive approach not only achieves better recognition accuracy, but also improves the filter's robustness when time delay estimates are inaccurate.

Download or read book Distant Speech Recognition written by Matthias Woelfel and published by John Wiley & Sons. This book was released on 2009-04-20 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete overview of distant automatic speech recognition The performance of conventional Automatic Speech Recognition (ASR) systems degrades dramatically as soon as the microphone is moved away from the mouth of the speaker. This is due to a broad variety of effects such as background noise, overlapping speech from other speakers, and reverberation. While traditional ASR systems underperform for speech captured with far-field sensors, there are a number of novel techniques within the recognition system as well as techniques developed in other areas of signal processing that can mitigate the deleterious effects of noise and reverberation, as well as separating speech from overlapping speakers. Distant Speech Recognitionpresents a contemporary and comprehensive description of both theoretic abstraction and practical issues inherent in the distant ASR problem. Key Features: Covers the entire topic of distant ASR and offers practical solutions to overcome the problems related to it Provides documentation and sample scripts to enable readers to construct state-of-the-art distant speech recognition systems Gives relevant background information in acoustics and filter techniques, Explains the extraction and enhancement of classification relevant speech features Describes maximum likelihood as well as discriminative parameter estimation, and maximum likelihood normalization techniques Discusses the use of multi-microphone configurations for speaker tracking and channel combination Presents several applications of the methods and technologies described in this book Accompanying website with open source software and tools to construct state-of-the-art distant speech recognition systems This reference will be an invaluable resource for researchers, developers, engineers and other professionals, as well as advanced students in speech technology, signal processing, acoustics, statistics and artificial intelligence fields.

Available in PDF, EPUB and Kindle. Book excerpt: Standard Object Systems, Inc. (SOS) has used its existing technology in phonetic speech recognition, audio signal processing, and multilingual language translation to design and demonstrate an advanced audio interface for speech recognition in a high noise military environment. The Phase 1 result was a design for a Phase 2 prototype system with unique dual microphone hardware with adaptive digital filtering for noise cancellation which interfaces to speech recognition software. It uses auditory features in speech recognition training, and provides applications to multilingual spoken language translation. As a future Phase 3 commercial product, this system will perform real time multilingual speech recognition in noisy vehicles, offices and factories. The potential market for this technology includes any commercial speech and translation application in noisy environments.
