Play Power Automate generated mp3 file in Canvas app

[Amersfoort]

Short: how to play a Power Automate generated mp3 file in a Canvas app?

Details:

I use Power Automate for the Azure Text-to-speech function. A canvas app calls the flow, which generates the speech result. Finally I send back the result of the speech function to the canvas app as a variable. How can I play this result with the Audio player in the canvas app? Do I have to convert this result to another format?

When I save the result of the speech function in power automate as One Drive mp3 file, I can play the mp3 with Windows media player using Windows 11. I do not intend to save the speech result as a mp3 file.

Hi @Amersfoort ,

Could you please share more details of your flow? How did you generate the file? Where are you saving this file?

Anyway, below is a similar thread from this forum for your reference:

Hope it helps.

I have created a Powerapps custom connector to Azure Microsoft Speech. In Power Automate I use this connector for Text-to-speech. I wanted to upload this result to the Canvas app.

In the mean time I have figured out, that the result of this Speech step has to be converted twice; starting with the binary option, and finally with the base64 option. Now I can play the speech audio in the Canvas app.

Where can I find when to use which conversion option using files of different formats in Power Automate?

EDIT: Compose step is not necessary.
