Unable to convert Speech to Text using Azure Speech-to-Text service

I'm using the below code to convert speech to text using Azure Speech-to-Text service.I want to convert my audio files into text.Below is the code for the same:

import  os
import  azure.cognitiveservices.speech  as  speechsdk



def  recognize_from_microphone():

# This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION"

    speech_config = speechsdk.SpeechConfig(subscription=my_key, region=my_region)

    speech_config.speech_recognition_language="en-US"

  
    audio_config = speechsdk.audio.AudioConfig(filename="C:\\Users\\DELL\\Desktop\\flowlly.com\\demo\\003. Class 3 - Monolith, Microservices, gRPC, Webhooks.mp4")

    speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)

  

    speech_recognition_result = speech_recognizer.recognize_once_async().get()

  

    if speech_recognition_result.reason == speechsdk.ResultReason.RecognizedSpeech:

        print("Recognized: {}".format(speech_recognition_result.text))

    elif  speech_recognition_result.reason == speechsdk.ResultReason.NoMatch:
        
        print("No speech could be recognized: {}".format(speech_recognition_result.no_match_details))

    elif  speech_recognition_result.reason == speechsdk.ResultReason.Canceled:

        cancellation_details = speech_recognition_result.cancellation_details

        print("Speech Recognition canceled: {}".format(cancellation_details.reason))

        if  cancellation_details.reason == speechsdk.CancellationReason.Error:

            print("Error details: {}".format(cancellation_details.error_details))

            print("Did you set the speech resource key and region values?")

  
recognize_from_microphone()

But Im getting this error when trying to run the transcriber:

I have installed the sdk for the same but its not working. What should I do now?

The currently supported format in Azure Speech-to-Text service is WAV (16 kHz or 8 kHz, 16-bit, and mono PCM).

• Convert your .mp4 file to WAV format. Ensure the converted WAV file has these specifications: Sampling rate: 16 kHz or 8 kHz, Bit depth: 16-bit. filename="path/to/your/converted_file.wav"

import os
import azure.cognitiveservices.speech as speechsdk

def recognize_from_audio_file():
    # Replace 'my_key' and 'my_region' with your actual subscription key and region
    my_key = "YourSubscriptionKey"
    my_region = "YourRegion"


    speech_config = speechsdk.SpeechConfig(subscription=my_key, region=my_region)
    speech_config.speech_recognition_language = "en-US"

    # Provide the path to your WAV audio file
    audio_file_path = r"C:\Users\samplest 3.wav"
    audio_config = speechsdk.audio.AudioConfig(filename=audio_file_path)

    speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)

    speech_recognition_result = speech_recognizer.recognize_once_async().get()

    if speech_recognition_result.reason == speechsdk.ResultReason.RecognizedSpeech:
        print("Recognized: {}".format(speech_recognition_result.text))
    elif speech_recognition_result.reason == speechsdk.ResultReason.NoMatch:
        print("No speech could be recognized: {}".format(speech_recognition_result.no_match_details))
    elif speech_recognition_result.reason == speechsdk.ResultReason.Canceled:
        cancellation_details = speech_recognition_result.cancellation_details
        print("Speech Recognition canceled: {}".format(cancellation_details.reason))
        if cancellation_details.reason == speechsdk.CancellationReason.Error:
            print("Error details: {}".format(cancellation_details.error_details))
            print("Did you set the speech resource key and region values?")

recognize_from_audio_file()
