Hi,
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,
Mar
