3. Write Some Code: Use the SDK to send text to the Azure TTS service and receive the audio output. Here's a basic example using Python:

import azure.cognitiveservices.speech as speechsdk

# Replace with your subscription key and region
subscription_key = "YOUR_SUBSCRIPTION_KEY"
region = "YOUR_REGION"

# Creates a speech configuration with your subscription key and region
speech_config = speechsdk.SpeechConfig(subscription=subscription_key, region=region)

# Creates a speech synthesizer using the default speaker
synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config)

# Text to be converted to speech
text = "Hello, Azure Text to Speech!"

# Synthesizes the text to speech
result = synthesizer.speak_text_async(text).get()

# Checks result
if result.reason == speechsdk.ResultReason.SynthesizingAudioCompleted:
    print("Speech synthesized to speaker: {}".format(text))
elif result.reason == speechsdk.ResultReason.Canceled:
    cancellation_details = result.cancellation_details
    print("Speech synthesis canceled: {}".format(cancellation_details.reason))
    if cancellation_details.reason == speechsdk.CancellationReason.Error:
        print("Error details: {}".format(cancellation_details.error_details))

Replace YOUR_SUBSCRIPTION_KEY and YOUR_REGION with your actual Azure subscription key and region. This code snippet demonstrates how to use the Azure Cognitive Services SDK to synthesize text to speech. It first creates a speech configuration object, which contains your subscription key and region. Then, it creates a speech synthesizer object, which is used to convert text to speech. The speak_text_async() method is used to send the text to the Azure TTS service and receive the audio output. The get() method blocks until the synthesis is complete. The code then checks the result to see if the synthesis was successful. If the synthesis was successful, it prints a message to the console. If the synthesis was canceled, it prints the cancellation details. This is a basic example, but it demonstrates the fundamental steps involved in using the Azure Text to Speech service. You can customize this code to meet your specific needs, such as changing the voice, adjusting the speaking rate, or adding SSML markup.
