Queue a text-to-speech message

Inject a text-to-speech message into Vivox channels.

Some destinations offer a built-in queuing system. When a new message is injected and there is an ongoing message playing, then the new message is put into a queue. After the ongoing message finishes playing, the next message in the queue automatically begins playing. 
// Returns VxErrorSuccess and starts playing immediately.MyLoginSession->TTS().Speak("First Message.", TTSDestination::QueuedLocalPlayback);// Returns VxStatusTTSInputTextWasEnqueued and put in a queue.// After the first message finishes playback, this message will start.MyLoginSession->TTS().Speak("Second Message.", TTSDestination::QueuedLocalPlayback);
A queue is shared between 
TTSDestination::QueuedRemoteTransmission
and 
TTSDestination::QueuedRemoteTransmissionWithLocalPlayback
. The destination 
TTSDestination::QueuedLocalPlayback
has its own queue. A destination queue can hold up to 10 messages. If a message is added when a destination queue is full, the Vivox SDK discards the message and the method returns the error 
VxErrorTTSDestinationQueueIsFull
. In this case, no text-to-speech related events are raised.
