Dear all, I'm recently switching my HTS project from HTS-2.01 to HTS-2.2. For using the English speaker dependent training demo from HTS-2.2 project. I installed HTS-2.2_for_HTK-3.4.1 without any trouble, and also change my HTS_Engine to 1.05. In fact, the whole training process went well smoothly, and the synthesized speech sounds good. But when I want to change the wave data to cmu-bdl (16KHz), I got very bad synthesized speech. The voice sounds broken, and the speed of the speech is also weird. I changed the feature extraction parameters in data/Makfile as: SAMPFREQ = 16000 &nb
sp; # 48000 Sampling frequency (48kHz) FRAMELEN = 400 # 1200 Frame length in point (1200 = 48000 * 0.025) FRAMESHIFT = 80 # 240 Frame shift in point (240 = 48000 * 0.005) WINDOWTYPE = 1 # Window type -> 0: Blackman 1: Hamming 2: Hanning NORMALIZE = 1 # Normalization -> 0: none 1: by power 2: by magnitude FFTLEN = 1024 # FFT length in point FREQWARP = 0.42 # 0.55 # frequency warping factor GAMMA = 0 # pole/zero weight for mel-generalized cepstral (MGC) analysis MGCORDER = 24 # order of MGC analysis LNGAIN = 1 # use logarithmic
gain rather than linear gain LOWERF0 = 40 # lower limit for f0 extraction (Hz) UPPERF0 = 400 # upper limit for f0 extraction (Hz) NOISEMASK = 50 # standard deviation of white noise to mask noises in f0 extraction and the training parameters in scrpits/Config.pm as # Speech Analysis/Synthesis Setting ============== # speech analysis $sr = 16000; #48000; # sampling rate (Hz) $fs = 80; #240; # frame period (point) $fw = 0.42; #0.55; # frequency warping $gm = 0; # pole/zero representation weight $lg = 1; # use log gain instead of linear gain $fr = $fs/$sr; # frame period (sec) # speech synthesis $pf = 1.4; # postfiltering factor $fl = 4096; # length of impulse response $co = 2047; # order of cepstrum to approximate mel-generalized cepstrum The rest of t
he training parameters remain the same, but I cannot get correct result from training. Could anyone tell me where can I possibly go wrong? Thanks in advance! Sincerely, Mandy |
