Evaluation of a correlation subtraction method for enhancing speech degraded by additive white noise
Jae S. Lim · IEEE Transactions on Acoustics Speech and Signal Processing · 1978
An intelligibility test was performed to evaluate a correlation subtraction method for enhancement of degraded speech due to additive white noise. Results indicate that such a scheme does not significantly increase speech intelligibility at the S/N ratios where the intelligibility scores of unprocessed speech range between 20 and 70 percent.
