Ommited index marks in SSML

[Hynek Hanke]

Dear Jonathan, Lukas,

the latest Speech Dispatcher CVS with espeak 1.36.02
(and very possibly later versions of both as well) are not
reporting certain index marks. It is easy to reproduce
for me.

For example in the text

<speak>for<mark name="w_for"/> the<mark name="w_the"/> use<mark 
name="w_use"/> of<mark name="w_of"/> anyone<mark name="w_anyone"/> 
anywhere<mark name="w_anywhere"/> at<mark name="w_at"/> no<mark 
name="w_no"/> cost<mark name="w_cost"/> and<mark name="w_and"/> 
with<mark name="w_with"/> almost<mark name="w_almost"/> no<mark 
name="w_no"/> restrictions<mark name="w_restrictions"/> whatsoever.<mark 
name="w_whatsoever."/></speak>

Given this text, "w_restrictions" is never reported by the Speech Dispatcher
espeak module and I suspect this is because eSpeak never sends
the callback. This is with the default English voice, no punctuation,
no capital letters recognition and no other special settings.

A slight modification in the text ''fixes'' the problem. For example
removing the dot in 'whatsoever.' both in text and in the index mark
causes w_restrictions to be reported correctly. Perhaps punctuation
in mark name is not a very good idea, but I didn't find anything in SSML
documentation that would rule it out. Removing the first word 'For' and
its index mark 'w_for' also results in correct behavior.

Please, do you have any ideas? It would be useful to test the above
text in espeak directly (without SD in the middle), but I don't
know how to do such a test without having to write my own code
(and possibly introduce the same bug).

Thank you,
Hynek Hanke
