[hts-users:04024] STRAIGHT voice problem

[Martin Sulír <martin.sulir@xxxxxxxxx>]

Hello,

I'm trying to train new HMM-based voice in Slovak language with STRAIGHT algoritm, but I have some problems.

Namely a lot of WARNINGs in step "Start embedded reestimation (clustered)":

No path found in beta pass
WARNING [-7324]  StepBack: Bad data or over pruning

and then many of these:

WARNING [-2331]  UpdateModels: l^k-o+u=a@2_2/A:1_1_3/B:0-0-3@2-1&3-11#2-5$2-5!1-2;1-2|o/C:0+0+1/D:content_1/E:content+2@2+6&2+5#1+1/F:content_1/G:0_0/H:13=7^1=2|NONE/I:13=6/J:26+13-2[25635] copied: only 0 egs

and also in step: "Start forced alignment for no-silent GV", where the algorithm goes over 5000 beam and I have no output.

WARNING [-9999]  HSMMAlign: No tokens survived to final node of network at beam 5000

When I use the same raw, utts and qst files with the "normal demo - Speaker dependent training"  everithing is fine, and I get new voices without problem. I use 4526 raw files with 48 kHz sampling rate. I checked everithing, every single step in algoritm and everithing seems to be fine. When I use another speech database with 300 raws, I get STRAIGHT voice withou problem.

I think that there might be something wrong with parameters extraction step, but I don't now where.

Please, do you know where the problem might be?

Thanks for your reply.
