Using asymmetric windows in automatic speech recognition
This paper considers the windowing problem of the short-time frequency analysis that is used in speech recognition systems (SRS). Since human hearing is relatively insensitive to short-time phase distortion of the speech signal there is no apparent reason for the use of symmetric windows which give a linear phase response. Furthermore, phase information is usually completely disregarded in SRS....
متن کاملOn the Use of Asymmetric Windows for Robust Speech Recognition
This paper deals with the problem of searching for a suitable window for robust speech recognition in noisy conditions. A set of asymmetric windows, socalled DDRc,w, are proposed which are controlled by two parameters, center c and width w. These windows are derived from the DDR window used in the higher-lag autocorrelation spectrum estimation (HASE) method and act over the OSA (OneSided Autoco...
متن کاملUsing Articulatory Knowledge in Automatic Speech Recognition
Over the years different types of speech recognizers have been proposed and tested. During the last decade (or maybe even longer) hidden Markov models (HMMs) seem to have a better performance than other types of speech recognizers, like e.g. rule-based speech recognizers. This state of affairs has led to a gap between speech technology on the one hand, and phonetics and phonology on the other. ...
متن کاملUsing Graphone Models in Automatic Speech Recognition
This research explores applications of joint letter-phoneme subwords, known as graphones, in several domains to enable detection and recognition of previously unknown words. For these experiments, graphones models are integrated into the SUMMIT speech recognition framework. First, graphones are applied to automatically generate pronunciations of restaurant names for a speech recognizer. Word re...
متن کاملAutomatic Speaker Recognition Using Msvq-coded Speech
Low bitrate speech coding nds application in both telecommunications (band-width compression) and archival ((le compression). Speaker veriication is used in telecom-munication applications (to gain access to particular services, for example) and implies that either or both of the speech data streams (incoming and reference) may be compressed. In this paper, we investigate the eeect of high comp...
