Remarks

A RecordMessageActivity has two phases: a recording phase in which the user can record a message and an action phase, in which the user can request that a particular action be performed. The recording phase starts when the RecordTurnStarting event occurs; the action phase starts when the ActionTurnStarting event occurs.

The default action-phase grammars for a RecordMessageActivity recognize the commands shown in the following table. The table also lists methods to use if you provide custom action-phase grammars.

Command	Description
accept	Accept the message that was recorded. See Accept.
cancel	Exit the RecordMessageActivity. See Abandon.
continue	Continue recording, starting at the end of the previous message. See Continue.
play back	Replay the message that was recorded. See Replay.
start over	Record a new message, abandoning the previous recorded message. See StartOver.

There are default grammars for RecordMessageActivity for each language that ships with Speech Server. For information about the default grammars for a particular language, see:
