Synthesizer RESUME

Reference Number: AA-01666 Views: 2825 0 Rating/ Voters

The RESUME method from the client to the server tells a paused synthesizer resource to resume speaking.  

If a RESUME request is issued on a session with no active SPEAK request, the server will respond with a status-code of 402 "Method not valid in this state".  If a RESUME request is issued on a session with an active SPEAK request that is speaking (i.e., not paused), the server will respond with a status-code of 200 "Success".  If a SPEAK request was paused, the server will return an Active-Request-Id-List header field whose value contains the request-id of the SPEAK request that was resumed.
