Question about the MFCC computation changes

(Mar Martinez) #1


I have observed that in the last release 0.4 the MFCC are computed in a different way, doubling the time interval-step instead of 2-striding, as well as using hamming function.

Does these changes have a high impact in the model WER? or if you have measured the effect of them and want to share any information about it. I would help me to take my own decisions.

Thanks a lot,

We had good preliminary results and are currently training models on our full training dataset to validate them. If everything goes OK this should go out with the v0.4 release.
