I’m trying to wrap up which TTS engine we will use over unimrcp. We’ll use between 10 and 40 simultaneous TTS lines.

So far I have tested the new IVONA mrcpv1 plugin but I am waiting on their dev’s to work out a few issues I uncovered.

Which TTS engines have been successfully used by others?

I’ve heard good things about Loquendo, but I have had problems getting in contact with them.

Acapela sounds nice on their website – does anybody know how their unimrcp plugin sounds?

Cepstral is cheap, but it seems as though they do not have a current release for Open Suse 11.6 (32bit).

Any others? Recommendations?
