[hts-users:02498] AW: using of HVite


Hi Sebastien,

Did you also take into account that HVite does not understand HSMMs (Hidden Semi Markov Models), as they are generated by the HTS demo ? In order to use HVite you would have to turn the HSMM (monophone.mmf) into a HMM. This can be done as described by Simon King [hts-users:01141].
You could also directly use
a decoding method for HSMMs based on weighted finite state transducers (WFSTs), as proposed in [hts-users:01143] but I haven't tried this yet.

Good luck,

Florian Krebs

Hi,

I've got a problem with HVite. It always returns "No tokens survived to final node of network". I would like to find how monophones are aligned.

I used this command :

./../tools/bin/HVite -A -B -C configs/trn.cnf -D -y lab -T 1  -o SW -f -a -H models/qst001/ver1/cmp/monophone.mmf -I data/labels/mono.mlf -i test/gen_align.mlf -S data/scp/train.scp data/dict/mono.dict data/lists/mono.list

mono.dict contains the same things that mono.list and all other files are generated from the HTS 2.1 demo (For the moment, I'm using HTS 2.1).

Here are samples of the messages I have:

Aligning File: <...>/demo/base/data/cmp/cmu_us_arctic_slt_b0538.cmp
Created lattice with 31 nodes / 30 arcs from label file
No tokens survived to final node of network
Aligning File: <...>/demo/base/data/cmp/cmu_us_arctic_slt_b0539.cmp
Created lattice with 32 nodes / 31 arcs from label file
No tokens survived to final node of network

I think I'm misunderstanding something.

Thanks
Sebastien
