Synthesizer CONTROL
The CONTROL method, sent from the client to the server, modifies what an actively speaking synthesizer is rendering—on the fly. It can request the synthesizer to jump forward or backward in the current prompt, change the speaking rate, or adjust other speaker parameters, and it affects only the currently IN-PROGRESS SPEAK request.
Not supported on Capacity Private Cloud. The CONTROL method is defined in both MRCPv1 and MRCPv2 but is not currently supported by the platform. To change speech that is already playing, stop the active SPEAK request and issue a new SPEAK with the desired rate, voice, or prosody settings.
