Postprocessing method for suppressing musical noise generated by spectral subtraction
Zenton Goh, Kah-Chye Tan, Tian Tan · IEEE Transactions on Speech and Audio Processing · 1998
We investigate whether musical noise, which often exists in speech enhanced using spectral subtraction, can be suppressed. Via exploiting some specific characteristics of human speech, we propose a method that can effectively suppress musical noise without a noticeable effect on speech intelligibility. Performance assessments confirm that our method is effective.
