SPECTRAL EFFICIENCY WITH TIME & PITCH SCALE MODIFICATION OF SPEECH SIGNAL

Abstract

This paper actualizes a calculation for estimation of signals from brief time extent spectra is presented offering a huge change in quality and effectiveness over current strategies. The essential issue is to address the overlapping frames in the wake of scaling. Another critical issue is to make the calculation computationally helpful for applications. The calculation is parameterized to permit tradeoffs between computational requests and the nature of the sign recreation. The calculation is implemented on sound signals time-scale and pitch scale.
