Re: [orca-list] Single-char silence with new Libao drivers+Orca (was Re: [ANNOUNCE] libao (new audio driver for speechd including working pulseaudio support).)

Hi,
I think the problem is related to pulseaudio.
The libao pulse driver doesn't implement any buffering stuff.
When you try to set orca's speech rate to 100% the samples are very
short and pulse tries to play it after buffering a few of it.
Workaround: reduce speechrate to 90% in orca to avoid the keyecho
problem.
It's a temporary workarround and i will do more work on this!

Another workarround is to use a different voice type.
Unfortunately voice variants can't be selected in orca.
espeak male3 seems working well with libao->pulse.

have Fun.
