Re: [orca-list] Does Orca use SSML tags other than speak and mark?

[Rastislav Kiss <rastislav kish gmail com>]

Hi there,
do you mean when reading the document with orca + semicolon?
Hmm, interesting, yes, it's quite buggy.
Unfortunately, this is Orca's problem, not Speech dispatcher's.

Orca is feeding SD with speak requests for every line, what causes the
problem. The speech engine sees just one line in time, so it can't
produce correct intonation.
Orca should instead pump-in the whole text in one speak request, or at
least one bigger chunk, if there is lot of it.
That way, the engine can see the context and intonate correctly.

Best regards

Rastislav
