• Custom Neural Voices: Create a unique brand voice using Microsoft’s AI model.
• SSML Support: Fine-tune speech with Speech Synthesis Markup Language for precise control over tone, pronunciation, and emphasis.
• Real-time & Batch Processing: Supports both live voice generation and pre-generated audio.
• Multiple Output Formats: Export speech in MP3, WAV, OGG, and other formats.
• Integration with Microsoft Services: Works seamlessly with Azure Speech SDK, Bot Services, and Power Automate.

How Does Azure Text to Speech Work?

Azure Text to Speech uses advanced deep learning models to synthesize speech in a way that sounds natural and lifelike. The process involves:

1. Text Input: Users provide text through an API, SDK, or Azure portal.
2. Linguistic Processing: The AI analyzes text structure, grammar, and semantics to enhance fluency.
3. Voice Selection & Customization: Choose from prebuilt voices or create a custom one.
4. Speech Generation: The model converts text into audio output, applying intonation, emotion, and natural pauses.
5. Delivery & Integration: Speech output is streamed in real-time or saved for later use.
