Azure Real Time Speech To Text fails to take input from Blob URL

Question

I have implemented Azure Real Time Speech to Text using Speech SDK in Python for pre recorded audio files. It works fine when the input audio is on my machine. But fails when I give the input as the Blob url containing the audio. Please help!

Hi Indira,

Thanks for sharing the code,I see you are using filename parameter to specify the BlobUrl. Instead make sure it is done in the below way

• Download audio file from Azure blob storage using container_client and write to temporary file on disk
• Pass the temporary file to the filename parameter in your above code.

Process audio :

 
 try:
        with open(filename, "wb") as audio_file:
            audio_data = container_client.download_blob(filename).readall()
            audio_file.write(audio_data)
        result = speechsdk.audio.AudioConfig(filename=filename, lang_id, speech_config)
    finally:
        os.remove(filename)
