Non-stationary acoustic objects as atoms of voiced speech
In spite of the undisputedly high degree of non-stationarity of speech signals, the present day determination of its acoustic features is based on the assumption that speech production can be described as a linear time invariant (LTI) system on the time scale of about 20 ms [1]. In automatic speech recognition, the wide sense stationarity of an LTI– system is used as prerequisite for the consis...
متن کاملVoiced-voiceless distinction in alaryngeal speech - acoustic and articula
In an investigation of the speech of layngedomized speakers we presently focus on their ability to distinguish behoeen voiced and voiceless speech sounds. Some of them are able to produce this distinction clearly in some contexts and it is quite remarkable considering the structure of the pharyngo-esophageal entrance, serving as the post-operative voice source. However, there are a number of ac...
متن کاملNon-stationary Self-consistent Acoustic Objects as Atoms of Voiced Speech
Voiced segments of speech are assumed to be composed of non-stationary voiced acoustic objects which are generated as stationary (secondary) response of a non-stationary drive oscillator and which are analysed by introducing a selfconsistent part-tone decomposition. The self-consistency implies that the part-tones (of voiced continuants) are suited to reconstruct a topologically equivalent imag...
متن کاملSingle acoustic-channel speech enhancement based on glottal correlation using non-acoustic sensor
This paper describes a single acoustic–channel speech enhancement, utilizing an auxiliary non-acoustic sensor. Unlike classical algorithms, which make use of the knowledge from acoustic signal alone, the glottal correlation (GCORR) algorithm takes advantage of non-acoustic throat sensors such as the general electromagnetic motion sensor (GEMS). The non–acoustic sensor provides a measure of the ...
متن کاملAn Introduction to Speech Sciences (Acoustic Analysis of Speech)
Speech sciences deal with the acoustical characteristics of speech by means of sophisticated soft wares as well as hard wares. Although, a speech science is a well known science in the developed countries, especially the western societies, however, it has been remained almost unknown in Iran, though, in recent years a group of scholars have been involved in this branch of science. The applicati...
