EARS: Novel Approaches
Pushing the envelope (aside):
Re-thinking Acoustic Processing for Speech Recognition
We are studying replacements of the standard spectral envelope (typically
with cepstral transformation) as the speech representation of choice .
This includes work on the acoustic "front end", and statistical modeling
for the new features that are being generated.
