Removal of Noise from a Voice Signal by Synthesis

Abstract

This report describes research into the problem of rectification of sound recordings made under adverse conditions and communicated and recorded with a great deal of noise. In the course of this research, a number of refinements have been made to the process of digital speech synthesis through new vocoder techniques. The particular case under investigation was that of old, noisy recordings of a singing voice and the immediate goal was the separation of that voice from wide band noise, orchestral accompaniment and recording noise. This has been accomplished by the development and refinement of the homomorphic vocoder as a filtering device.
