Synthesizer PAUSE
The PAUSE method from the client to the server tells the synthesizer resource to pause speech output if it is speaking something.
If a PAUSE method is issued on a session when a SPEAK is not active, the server will respond with a status-code of 402 "Method not valid in this state". If a PAUSE method is issued on a session when a SPEAK is active and is already paused, the server will respond with a status-code of 200 "Success".
If a SPEAK request was active, the server will return an Active-Request-Id-List header field whose value contains the request-id of the SPEAK request that was paused.
