[hts-users:04521] Re: too few observation sequences

if (segEnIdx - segStIdx + 1 >= nStates - 2) { LoadSegment(segStore, p->start, p->end, pbuf); if (trace & T_LD1) printf(" loading seg %s %f[%ld]->%f[%ld]\n", segId->name, p->start, segStIdx, p->end, segEnIdx); nObs += SegLength(segStore, segIdx); segIdx++; } else if (trace & T_LD1) printf(" seg %s %f->%f ignored\n", segId->name, p->start, p->end);
So I think that your segments are too short.

And it turns out it loads no observations because it ignores all instances of the phoneme, like this:

 0 observations loaded from /proj/tts/voices/babel/amharic_female/data/cmp/BABEL_OP3_307_51611_20140423_232011_inLine_120.cmp
   seg dw 31170101.000000->31328700.000000 ignored
   seg dw 31328700.000000->31485200.000000 ignored

Do you have any idea why this would happen? The frame length is set to 1200 in the Makefile in the data/ dir.

Thank you!

First let's increase HInit's trace level (-T) and output more fine-grain logs.  It will tell you more details why it failed.

One possibility is that HInit internally failed to run Viterbi alignment over all 'dw' segments.

Hi hts-users,

We are training a new voice and running into this error:

We understand that this error may happen because of too few examples of the phoneme, or because they don't each contain enough frames, but we have more than 3 examples of this phoneme in our data (the minimum specified in the HTK book) and they all contain more than 5 frames (which sounds like the minimum required according to other posts on this list) -- is there any other reason why this error may occur?
