The audio client today only uses the "prompt" value from the attribute in the "action": "text" message as below: ```json { "speech": "I am not trained for this", "voice": "https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize?voice=en-US_LisaVoice&text=I%20am%20not%20trained%20for%20this&watson-token=xc9D......ATB", "id": "aa16b1e9-xxxx-xxxx-xxxx-58b7f7df23d7", "language": "en-US", "audioFormat": "ogg;codecs=vorbis", "prompt": true, "action": "text" } ``` It does NOT however take notice of the value in audio_end: ```json { "action": "audio_end", "id": "aa16b1e9-xxxx-xxxx-xxxx-58b7f7df23d7", "prompt": true } ``` They should arguably always be the same however maybe there is also a bug in the AudioGateway as we are seeing differences in these values.
