Azure Speech To Text API not accepting Base 64

Posted on by 5

When I am calling a flow from Power Portals to hit the Azure Speech to Text Rest API. I am send the Base 64 string of the WAV file recorded on portal but I am getting the below response from the API:-

{
"RecognitionStatus": "Success",
"Offset": 300000,
"Duration": 301200000,
"DisplayText": ""
}

I asked this question in Microsoft Learn aas well but no help there. PFB the link for that request :-
