I'm trying to get the Azure Text to Speech Service in Power Automate to output to a audio file.
Flow saving successfully and file is created, but the encoding must be incorrect:

Hey! I'm not sure if you ever figured this out, this post is from a lonnggg time ago... but I had the same issue as you. You need to convert the body of the Convert Text to Speech output to binary before creating the file.
You can use a compose action:
base64ToBinary(body('Convert_text_to_speech'))
Then use the output of the compose action as your file content.
Good luck!
@Darren Nixon Did you try to save it in a different format in the flow and use media player to play the audio? I think the app you are using is unable to recognize the format or the file is corrupted which might be causing the issue.
