Abstract :
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.
