Thanks for announcing this.

Your message may leave the hts-user hungry for
a bit more information:

What did you use for the decoding: WFSTs or Simon's
HVite-based recipe? (Or did you not use HSMMs at all?)

Did you use a language model? If yes, what kind of LM?

What kind of questions did you use for the state clustering:
quinphones only, or quinphones+phonological features, or
a full set of TTS-like context features, or something else?

Would you please remind us what are the other relevant
system differences between HTK and HTS, besides
the MDL criterion and possibly the HSMMs? E.g.,
did you use semi-tied covariances?

Is it planned to release MPE as part of HTS-2.1?
Would MPE then apply to the HSMMs as well?


Thanks and best regards;
