[hts-users:02047] Re: poor quality of short sentences

["Nicholas Volk" <nvolk@xxxxxxxxxx>]

It's all in the speech database.

If you don't have any 1 or 2 word training material, bad things can happen.
For example, for 1 word utterance the first word is also the last word.
Then you have a question like "last word in the utterance" early on in
your tree(s), and a less-than-optimal path gets chosen... For example
utterance final stuff is usually lengthened, and this lengthening spreads
also to utterance initial areas, where (depending on the target language)
it should not be...
