Guidance/Play text-to-speech audio


The Play TextToSpeech Audio behavior uses a synthesized voice to read text.


The default Text-to-Speech language is set to English. Check out our online tutorial to learn how to configure the Text-to-Speech Engine (TTS).


Here you can input the text to be synthesized by the TTS engine.

Execution stages

By default, steps execute behaviors in the beginning, in their activation stage. This can be changed with the Execution stages dropdown menu:

  • Before Step Execution: The step invokes the behavior during its activation.
  • After Step Execution: Once a transition to another step has been selected and the current step starts deactivating, the behavior is invoked.
  • Before and After Step Execution: Execution at activation and deactivation of a step.

Wait for completion

By default, the step waits for the audio file to finish. If you want the step to interrupt the audio in case the trainee completes the conditions, uncheck this option.

Note: this might lead to an audio file not even being started.
