Yes. Because in the current implementation the index mark
reporting is not independent of the audio output, so the artefact
of this is slightly higher delays between the words.

Festival also supports it. I'd however suggest to invest work
into completing TTS API Provider and the new implementation
of Speech Dispatcher now than to create various bindings
for the various synthesizers and and hardcode them with the
applications. It's the easiest and fastest way forward.
