Book Synopsis New Spectral Methods for Analysis of Source/filter Characteristics of Speech Signals by : Baris Bozkurt
Download or read book New Spectral Methods for Analysis of Source/filter Characteristics of Speech Signals written by Baris Bozkurt and published by Presses univ. de Louvain. This book was released on 2006 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study proposes a new spectral representation called the Zeros of Z-Transform (ZZT), which is an all-zero representation of the z-transform of the signal. In addition, new chirp group delay processing techniques are developed for analysis of resonances of a signal. The combination of the ZZT representation with the chirp group delay processing algorithms provides a useful domain to study resonance characteristics of source and filter components of speech. Using the two representations, effective algorithms are developed for: source-tract decomposition of speech, glottal flow parameter estimation, formant tracking and feature extraction for speech recognition. The ZZT representation is mainly important for theoretical studies. Studying the ZZT of a signal is essential to be able to develop effective chirp group delay processing methods. Therefore, first the ZZT representation of the source-filter model of speech is studied for providing a theoretical background. We confirm through ZZT representation that anti-causality of the glottal flow signal introduces mixed-phase characteristics in speech signals. The ZZT of windowed speech signals is also studied since windowing cannot be avoided in practical signal processing algorithms and the effect of windowing on ZZT representation is drastic. We show that separate patterns exist in ZZT representations of windowed speech signals for the glottal flow and the vocal tract contributions. A decomposition method for source-tract separation is developed based on these patterns in ZZT. We define chirp group delay as group delay calculated on a circle other than the unit circle in z-plane. The need to compute group delay on a circle other than the unit circle comes from the fact that group delay spectra are often very noisy and cannot be easily processed for formant tracking purposes (the reasons are explained through ZZT representation). In this thesis, we propose methods to avoid such problems by modifying the ZZT of a signal and further computing the chirp group delay spectrum. New algorithms based on processing of the chirp group delay spectrum are developed for formant tracking and feature estimation for speech recognition. The proposed algorithms are compared to state-of-the-art techniques. Equivalent or higher efficiency is obtained for all proposed algorithms. The theoretical parts of the thesis further discuss a mixed-phase model for speech and phase processing problems in detail. Index Terms—spectral representation, source-filter separation, glottal flow estimation, formant tracking, zeros of z-transform, group delay processing, phase processing.

Book Synopsis Audiovisual Speech Recognition: Correspondence between Brain and Behavior by : Nicholas Altieri
Download or read book Audiovisual Speech Recognition: Correspondence between Brain and Behavior written by Nicholas Altieri and published by Frontiers E-books. This book was released on 2014-07-09 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perceptual processes mediating recognition, including the recognition of objects and spoken words, is inherently multisensory. This is true in spite of the fact that sensory inputs are segregated in early stages of neuro-sensory encoding. In face-to-face communication, for example, auditory information is processed in the cochlea, encoded in auditory sensory nerve, and processed in lower cortical areas. Eventually, these “sounds” are processed in higher cortical pathways such as the auditory cortex where it is perceived as speech. Likewise, visual information obtained from observing a talker’s articulators is encoded in lower visual pathways. Subsequently, this information undergoes processing in the visual cortex prior to the extraction of articulatory gestures in higher cortical areas associated with speech and language. As language perception unfolds, information garnered from visual articulators interacts with language processing in multiple brain regions. This occurs via visual projections to auditory, language, and multisensory brain regions. The association of auditory and visual speech signals makes the speech signal a highly “configural” percept. An important direction for the field is thus to provide ways to measure the extent to which visual speech information influences auditory processing, and likewise, assess how the unisensory components of the signal combine to form a configural/integrated percept. Numerous behavioral measures such as accuracy (e.g., percent correct, susceptibility to the “McGurk Effect”) and reaction time (RT) have been employed to assess multisensory integration ability in speech perception. On the other hand, neural based measures such as fMRI, EEG and MEG have been employed to examine the locus and or time-course of integration. The purpose of this Research Topic is to find converging behavioral and neural based assessments of audiovisual integration in speech perception. A further aim is to investigate speech recognition ability in normal hearing, hearing-impaired, and aging populations. As such, the purpose is to obtain neural measures from EEG as well as fMRI that shed light on the neural bases of multisensory processes, while connecting them to model based measures of reaction time and accuracy in the behavioral domain. In doing so, we endeavor to gain a more thorough description of the neural bases and mechanisms underlying integration in higher order processes such as speech and language recognition.

Book Synopsis Advances in Neural Information Processing Systems 7 by : Gerald Tesauro
Download or read book Advances in Neural Information Processing Systems 7 written by Gerald Tesauro and published by MIT Press. This book was released on 1995 with total page 1180 pages. Available in PDF, EPUB and Kindle. Book excerpt: November 28-December 1, 1994, Denver, Colorado NIPS is the longest running annual meeting devoted to Neural Information Processing Systems. Drawing on such disparate domains as neuroscience, cognitive science, computer science, statistics, mathematics, engineering, and theoretical physics, the papers collected in the proceedings of NIPS7 reflect the enduring scientific and practical merit of a broad-based, inclusive approach to neural information processing. The primary focus remains the study of a wide variety of learning algorithms and architectures, for both supervised and unsupervised learning. The 139 contributions are divided into eight parts: Cognitive Science, Neuroscience, Learning Theory, Algorithms and Architectures, Implementations, Speech and Signal Processing, Visual Processing, and Applications. Topics of special interest include the analysis of recurrent nets, connections to HMMs and the EM procedure, and reinforcement- learning algorithms and the relation to dynamic programming. On the theoretical front, progress is reported in the theory of generalization, regularization, combining multiple models, and active learning. Neuroscientific studies range from the large-scale systems such as visual cortex to single-cell electrotonic structure, and work in cognitive scientific is closely tied to underlying neural constraints. There are also many novel applications such as tokamak plasma control, Glove-Talk, and hand tracking, and a variety of hardware implementations, with particular focus on analog VLSI.

Book Synopsis Current Topics in Primate Vocal Communication by : U. Jürgens
Download or read book Current Topics in Primate Vocal Communication written by U. Jürgens and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 25 years ago, the first major review of primate communication appeared (Altmann, 1967). Since then, information on the communicative abilities of primates increased rapidly, resulting, 15 years later, in the appearance of the first volume in which signaling systems were analyzed in a broader variety of primate groups within an evolutionary perspective (Snowdon, Brown and Petersen, 1982). Seven years later, the first volume dedicated solely to primate vocal communication appeared (Todt, Goedeking and Symmes, 1988) and another four years later a volume followed in which nonverbal vocal communication in non-human primates and human infants was compared (Papousek, Jurgens and Papousek, 1992). None of these volumes, however, provided information about current technical advances in the field of bioacoustics, especially in digital sound analyzing systems, which offer primatologists, anthropologists and linguists nowadays a variety of rapid methods for analyzing human speech and non-human primate vocalizations in a quantitative and comparative way. Choosing the right method is difficult if a synopsis of these tools is lacking. Furthermore, information was particularly lacking on the natural signaling systems of two important primate groups, the prosimians and the apes. Likewise, new and unexpected insights into the ontogeny and evolution of vocal communication were gained during the past few years by the use of highly sophisticated sound analysis and statistical techniques.
