Azure speech to text API call in flow - error

(0) ShareShare
ReportReport
Posted on by jlhuang12 Microsoft Employee

Hi,

 

I am new to Power Automate, and was building a flow to call Azure speech to text API. The following error occurred.

 

"The provided input content is not valid: 'The provided content-type header value 'Content-Type: audio/ogg; codecs=audio/opus; samplerate=16000' is not well formed.'."

 

I used the microphone in Power Platform to collect the voice msg, and feed it into Azure speech-to-text API. The microphone generated ogg files, which should be ingested by speech-to-text API.

 

Any help/feedback is greatly appreciated. Thank you in advance.

    Thanks for the response, @ChristianAbata. I was following the tutorial. However, the microphone file came back as ogg format in the current power platform, so the format transformation was not necessary. Meanwhile, the link of downloading ffm executable was broken. 

     

    My question is how to transform the ogg file from microphone in power platform into ogg format that can be used for speech-to-text API. Thanks.
