HMM automatic vowel detection

[MarcoP]

Marco, would it be possible to alter the input text to test some hypotheses?

Specifically, I'm interested in what difference it would make if [a] and [y] were transcribed with the same character, and further if a [y] was placed between [e] and [d] when they appeared in the string [ed].

If they lead to a stronger split between the two states, with less looping, would that be a positive sign?

Hi Emma,
of course it's easy to modify the input file. What is difficult is comparing results with different inputs. I think that the first result I discussed above already provided a strong split between states.

With the edits you suggest, the results change. The two states still alternate. Now one of the states generates 9, O, S, Z and Q (but this last is ambiguous). With respect to the non-edit model, space and C (EVA:e) are excluded in favor of EVA:ch and sh.
Since A and 9 were already generated by the same state, I don't think that making them identical can change things significantly. The changes must be due to  C8 ed becoming C98 eyd.
