This results in a far more engaging and lifelike listening experience for the end-user. Moreover, Azure TTS is designed to be highly customizable, allowing developers to fine-tune the output speech to meet specific requirements. You can adjust parameters such as speaking rate, pitch, and volume, and even add pauses or emphasis to certain words or phrases. This level of control enables you to create speech that is not only natural-sounding but also tailored to the specific context and purpose of your application. Furthermore, Azure TTS supports a wide range of languages and voices, with new ones being added regularly. Whether you need a British English accent, a Mandarin Chinese voice, or a Spanish narration, Azure TTS has you covered. The service also offers different voice styles, allowing you to choose the tone and emotion that best suit your content. For example, you can select a cheerful and upbeat voice for a children's story or a professional and authoritative voice for a business presentation. With its advanced features, customization options, and extensive language support, Azure TTS is a powerful tool for adding voice capabilities to a wide range of applications and services.

region = "YOUR_REGION"

# Configure speech synthesis
speech_config = speechsdk.SpeechConfig(subscription=subscription_key, region=region)
speech_config.speech_synthesis_voice_name = 'en-US-JennyNeural'

# Create a speech synthesizer
speech_synthesizer = speechsdk.SpeechSynthesizer(speech_config=speech_config)

# Text to synthesize
text = "Hello, Azure Text to Speech!"

# Synthesize speech and save to file
result = speech_synthesizer.speak_text_async(text).get()

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))

Remember to replace YOUR_SUBSCRIPTION_KEY and YOUR_REGION with your actual Azure credentials.
