[mary-users] Building HMM voices in 22050 Hz

[Marcela Charfuelan]

Dear Anderson de Oliveira Monte,

The default settings are for 16Kz,
HMMVoiceConfigure.fftLen 512
HMMVoiceConfigure.frameLen 400  (0.025 sec)
HMMVoiceConfigure.frameShift 80   (0.005 sec)
HMMVoiceConfigure.freqWarp 0.42

so if you want to train with 22050, please take into account the 
following settings:

HMMVoiceConfigure.fftLen 512
HMMVoiceConfigure.frameLen ~ 550  (0.025*22050)
HMMVoiceConfigure.frameShift ~ 110  (0.005*22050)
HMMVoiceConfigure.freqWarp  0.45

Frequency warping factor:
8000 FREQWARP=0.31
10000 FREQWARP=0.35
12000 FREQWARP=0.37
16000 FREQWARP=0.42
22050 FREQWARP=0.45
32000 FREQWARP=0.45
44100 FREQWARP=0.53
48000 FREQWARP=0.55

Regards,
Marcela.
