I'm building a automation control application which has an audio stream. I want 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 EventSocket. 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? TIA, Gerry
