Speech SDK for Python crashes on text-to-speech synthesis

See original GitHub issue

Describe the bug Text-to-speech crashes in Google Colab (one of the most popular Jupyter Notebook environments). It’s the only Python environment I have at my disposal, so I simply don’t know the real extent of this bug.

To Reproduce Steps to reproduce the behavior:

Open the provided quickstart notebook in Colab.
Install requirements as instructed and proceed to running cells as usual.
Observe crash & restart when running cell result = speech_synthesizer.speak_text_async(text).get() (second to last cell in the quickstart notebook)

Expected behavior System should not crash without an error message. Error should be handled correctly with a message, or better yet, error should not occur and synthesized speech audio should be provided instead.

@olaviinha Thanks for the report and log. The problem happens probably because playback device is not found.

Clearly SDK should not crash and needs to inform about this with appropriate error. We have created internal work item about this and let you know once it is fixed.

Thanks! I further found that this way it works just fine and dandy:

audio_config = AudioOutputConfig(filename='/content/audiofile.wav')
synthesizer = SpeechSynthesizer(speech_config=speech_config, audio_config=audio_config)
result = speech_synthesizer.speak_text_async(text)

So it must be something in the .get() part:

result = speech_synthesizer.speak_text_async(text).get()
