I'm building a automation control application which has an audio stream.  I
an IVR to allow the callee to manipulate the application while the stream
is playing.
(the audio is interfaced via soundcard/portaudio.)

I'm using the latest Build of FSClient, and interfacing to it with

I'm using EventSocket to gather digits and play TTS to the caller.

The OS is Windows 7/64, and running all these apps in 32-bit.  6GB memory,
dual-core processor.
While I'm in a call, and playing TTS, CPU running at about 25% and memory
about 60%
(lots of stuff running on the box).

It does not matter if TTS is flite or cepstral, I get a bad chop at about a
1Hz or more rate.
I've tried flite and both 16 and 8-kHz cepstral voices, same issue.

Am I doing something wrong, or is this a bug?
