Check latest Acoustic Model build 798 - 8kHz:16bit model not recognizing as well as it should

Reported by: kmaclean Owned by: kmaclean
Priority: major Milestone: Acoustic Model 0.1.2
Component: Acoustic Model Version: 0.1-alpha
Keywords: Cc:


Problem might be related to Audacity's noise removal algorithm.

  • the 16kHz:16bit (build 798) Acoustic Model seems to work OK with audio that has been modified with Audacity's noise removal algorithm.
  • the 8kHz:16 bit (build 798) Acoustic Model has terrible recognition ... need further testing to isolate the problem.

Need to compare and test performance against the current release build 726.

  • Status changed from new to closed
  • Resolution set to fixed

Ran Acoustic Model creation script only on audio that had *no* noise reduction.

8kHz:16bit Acoustic Model performed much better on manual voice tests.

Need some more experimentation with noise reduction audio to understand impacts of noise reduction on acoustic model creation.
