Time and frequency scale modification of speech signals
This paper presents new and improved methods for independently modifying the time and pitch scale of acoustic signals, with an emphasis on speech signals. The algorithms developed here use parametric (sinusoidal) modelling techniques introduced by other authors, but new ideas are presented here that achieve improved output quality with decreased computational load. In particular, speech quality...
متن کاملMACH1: nonuniform time-scale modification of speech
Time-compression techniques change the playback rate of speech without introducing pitch artifacts. However, when linear-compression techniques are used, human comprehension of time-compressed speech typically degrades at compression rates above two times real time [1]. These degradations are not due to the speech rate per se: Comprehension of linearly compressed speech often breaks down above ...
متن کاملVoice source analysis for pitch-scale modification of speech signals
Much research has shown that the voice source has strong influence on the quality of speech processing [4][5][6]. But in most of the existing speech modification algorithms, the effect of the voice source variation is neglected. This work explains why the existing modification scheme can’t truly reflect the voice source variation during pitch modification. We use synthesized voiced speech sound...
متن کاملEpoch-Synchronous Overlap-Add (ESOLA) for Time- and Pitch-Scale Modification of Speech Signals
Timeand pitch-scale modifications of speech signals find important applications in speech synthesis, playback systems, voice conversion, learning/hearing aids, etc.. There is a requirement for computationally efficient and real-time implementable algorithms. In this paper, we propose a high quality and computationally efficient timeand pitch-scaling methodology based on the glottal closure inst...
متن کاملA Review of Time-Scale Modification of Music Signals
Time-scale modification (TSM) is the task of speeding up or slowing down an audio signal’s playback speed without changing its pitch. In digital music production, TSM has become an indispensable tool, which is nowadays integrated in a wide range of music production software. Music signals are diverse—they comprise harmonic, percussive, and transient components, among others. Because of this wid...
