Hi,
How about following options for speed up?
Sampling rate: 16000Hz -> 8000Hz (down-sampling of training data is required)
Number of states: 5 -> 3
Frame shift: 5ms -> 10ms
Audio bufffer: 800 (synthesized speech samples should be threw into
audio device directly)
GV: off
Postfilter: off
Alpha: 0.0
Feature: 12th order LSP and Log F0
MDL thresshold: 1.0 -> 3.0
Regards,
Keiichiro Oura
