Speech signal enhancement

Some classic speech enhancement algorithms.

Posted by WT on May 18, 2019


I chose a course about speech signal processing this semester. So I read some paper on speech enhancement (SE).

The following list shows the algorithms commonly used in SE and the databases.

You can download the codes and the databases here.

  • The over-subtraction approach (By Berouti)

  • The multi-band approach (Kamath)

Wiener Filter algothrim

Statistical Model-based algothrim

  • MMSE (Malah)

Subspace algothrim

  • Karnuhen-Loeve Transform (KLT)
