Abstract
A theoretical framework for analysis of speech enhancement algorithms is introduced
for performance assessment of spectral subtraction type of methods.
The quality of the enhanced speech is related to physical quantities of the speech
and noise (such as stationarity time and spectral flatness), as well as to design variables
of the noise suppressor. The derived theoretical results are compared with the outcome
of subjective listening tests as well as successful design strategies, performed by independent
research groups.
