I'm using Microsoft Cognitive Services Voise to Text in my Asp.Net application.
How can I pass base64string from my c# controller to SpeechRecognizer?
Thank you!

According to the documentation an audio file is passed to the Azure Services. Can you provide some insight the base64 string? Is it an audio file?

May I understand that you have a base64 string to represent one of the voice formats? And there's the c# sample codes which might be helpful to you.

I'm recording a Microphone record from my frontend with javascript and converting to wav format and passing to my backend as base64string. Base64string is a audio wav file. -

2024-07-24T09:50:26.5+00:00 Hi Sviatlana, then we could follow this section. We have base64string now instead of a wav file.
var reader = new BinaryReader(File.OpenRead("PathToFile.wav")); We could see
var reader = new BinaryReader(File.OpenRead("PathToFile.wav"));the tutorial is trying to convert the file to stream. So that I'm afraid we could tryvar stream = new MemoryStream(Convert.FromBase64String(base64));replace
File.OpenRead("PathToFile.wav")then we can use the sample code. Could you please help try it?
