? Supports multiple languages and voice styles

? Enables real-time streaming for interactive applications

?? Why Amazon Polly Rocks

1. Lifelike Speech Synthesis: Uses deep learning to create natural and expressive voices.
2. Neural TTS & Standard TTS: Choose between high-fidelity neural voices or cost-effective standard ones.
3. Custom Lexicons & SSML Support: Fine-tune pronunciation and adjust speech dynamics for better control.

?? Pro Tips for Amazon Polly Mastery

1. Use SSML tags to add pauses, change pitch, and emphasize words.
