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.
Spectral Subtraction algothrim
The over-subtraction approach (By Berouti)
The multi-band approach (Kamath)
Wiener Filter algothrim
Statistical Model-based algothrim
- MMSE (Malah)
- Karnuhen-Loeve Transform (KLT)
