RAPT

My research is in the area of digital processing of speech with specific application to speech enhancement. Speech Enhancement is an important process with applications in many fields.

WAVEIO

My first area of research wa to look at LCQA and P563 algorithms for non-intrusive speech quality measurement. It was found that Pitch Tracking has an important role in LCQA with the effeciency of pitch tracking in noise being an important issue.

LCQA

Looked at RAPT and YIN algorithms as well as the pitch tracker from P563 and evaulated their performance in various noise conditions:
