[orca-list] Orca: how to change voice dynamically

[anila susan <anila kurian gmail com>]

Hi,

I'm  working on a text to speech synthesis using festival, for Indian languages.
We are using Orca as the screen reader.
I'm not familar with orca source code.
Im facing an issue and hope someone might be able to help me out.

We want orca to change the voice selected dynamically depending on the text that is available. Say, if we have opened an English text it should read it out in English using the voice kal_diphone, if the text is in some Indian languages, it should select the corresponding voice and read out.
For this, which files of orca should I be modifying ?
Can anybody give me an idea how to proceed with this.

Thanks a lot,
Anila.
