Download or read book Effect of Spectral Shift and Compression Expansion on Speech Perception written by Ganesh Attigodu Chandrashekar and published by LAP Lambert Academic Publishing. This book was released on 2011-08 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on amplitude, temporal and spectral cues in speech show that speech recognition is only mildly affected when there in distortions in amplitude or temporal domains. But speech recognition is highly dependent on spectral cues. The present study aimed to find out the combined effects of the two spectral distortions, shift and compression-expansion, on speech recognition. Results from the present study reveal that speech recognition is affected when spectral distortions were present. Information from the present study on speech recognition in spectrally shifted and compressed-expanded conditions will helps in understanding the sensitivity of speech recognition to spectral manipulations. This will ultimately improve the fitting of an implant speech processor during cochlear implant.

This book was released on 2011 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Speech is the dominant mode of communication between humans; simple to learn, easy to use and integral for modern life. Given the importance of speech, development of a human-machine speech interface has been greatly anticipated. This challenging task is encapsulated in the digital speech processing research field. In this dissertation, two specific areas of research are considered: 1) the use of short-time Fourier spectral phase in digital speech processing and 2) use of the minimum mean square error spectral energy estimator for environment-robust automatic speech recognition. In speech processing and modelling, the short-time Fourier spectral phase has been considered of minor importance. This is because classic psychoacoustic experiments have shown speech intelligibility to be closely related to short-time Fourier spectral magnitude. Given this result, it is unsurprising that the majority of speech processing literature has involved exploitation of the short-time magnitude spectrum. Despite this, recent studies have shown useful information can be extracted from the spectral phase of speech. As a result, it is now known that spectral phase possesses much of the same intelligibility information as spectral magnitude. It is this avenue of research that is explored in greater detail within this dissertation. In particular, we investigate two phase derived quantities {u2013} the short-time instantaneous frequency spectrum and the short-time group delay spectrum. The properties of both spectra are investigated mathematically and empirically, identifying the relationship between known speech features and the underlying phase spectrum. We continue the investigation by examining two related quantities {u2013} the instantaneous frequency deviation and the group delay deviation. As a result of this research, two novel phase-based spectral representations are proposed, both of which show a high degree information applicable to speech processing.

This book was released on 2013-01-01 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the theory, algorithms, and implementation techniques for efficient decoding in speech recognition mainly focusing on the Weighted Finite-State Transducer (WFST) approach. The decoding process for speech recognition is viewed as a search problem whose goal is to find a sequence of words that best matches an input speech signal. Since this process becomes computationally more expensive as the system vocabulary size increases, research has long been devoted to reducing the computational cost. Recently, the WFST approach has become an important state-of-the-art speech recognition technology, because it offers improved decoding speed with fewer recognition errors compared with conventional methods. However, it is not easy to understand all the algorithms used in this framework, and they are still in a black box for many people. In this book, we review the WFST approach and aim to provide comprehensive interpretations of WFST operations and decoding algorithms to help anyone who wants to understand, develop, and study WFST-based speech recognizers. We also mention recent advances in this framework and its applications to spoken language processing.
