Speak

An action block that speaks a message using text-to-speech (TTS) to an audio stream.

If the proceed option is set to Immediately, then the message will be spoken without pausing the fiber. If set to When complete, then the fiber will pause until the speech has completed.

The message may be an SSML document, if the TTS engine supports it.

Playback can be stopped prematurely by an Speak stop block or by cancelling the notification.

Note! Few devices support playback in phone calls through the Voice call audio stream.
