Hi,

Recently i've run this command:

HVite -H model\hmm24\macros -H model\hmm24\hmmdefs -S test.scp -i recout.mlf -w wdnet -p 0.0 -s 5.0 dict monophones

 It gave me this error:

 Warning[-8232] ExpandWordNet: Pronounciation 1 of sp is 'tee' word in HVite

Error[+8521] MovetoRecent: Loop resulted in circular move

Can anyone help me with this, pls... ??

Thanks so much!!

Hi crystal,

> Warning[-8232] ExpandWordNet: Pronounciation 1 of sp is 'tee' word in HVite

The HTK Book states the following:

 

7.8 Tee Models 

Normally, the transition probability from the non-emitting entry state to the non-emitting exit state of a HMM will be zero to ensure that the HMM aligns with at least one observation vector. Models which have a non-zero entry to exit transition probability are referred to as tee-models.  

Tee-models are useful for modeling optional transient e?ects such as short pauses and noise bursts, particularly between words.

[...] 

 +8232 Lattice badly formed
      Could not convert lattice to network. The lattice should have a single well de?ned start and a single well de?ned end. When cross word expansion is being performed the number of !NULL words that can be concatenated in a string is limited. 

For questions like this, it is sometime very helpful to download the entire HTK users and developers mailing lists, and search through them to see if your answer might be there.  See these links (you need to be logged in to HTK to download these ...):

One email datd 30 Jan 2002 from Gunnar Evermann states:

[...]

This means that you have a word in your dictionary ("sp") that has a pronunciation that only consists of a tee model. Don't do that.

This warning is okay it is meant for anything other than sp.  Note the HTK Handbnook Section 3.2.2: "Also, at this point, a 1 state short pause sp model should be created. This should be a so-called tee-model which has a direct transition from entry to exit node. This sp has its emitting state tied to the centre state of the silence model. The required topology of the two silence models is shown
in Fig. 3.9."
