cServer Text-to-Speech Server

The CereProc cServer 3.1.0 is a high performance, multi-channel, text-to-speech (TTS) server. It is ideally suited to multi-threaded environments, supporting applications such as IVR, alert systems, multimedia, web reading, chatbots, and many more. CereProc's speech tuning functionality allows the same voice to be used for static and dynamic content, with results almost indistinguishable from human speech.

The cServer supports a range of client-side APIs, including MRCP (via the cServer MRCP Connector), Microsoft SAPI 5, and CereProc cSpeech (C/C++/Python). Speech output is supported at 8khz (IVR) or 22khz (multimedia).
