## TL;DR

- Amazon Polly introduces a new Bidirectional Streaming API that enables real-time TTS synthesis – sending text and receiving audio happen simultaneously.

---

## Summary

- Amazon Polly introduces a new Bidirectional Streaming API that enables real-time TTS synthesis – sending text and receiving audio happen simultaneously.
- Designed for conversational AI apps where LLM responses are generated incrementally and waiting for full text completion is not an option.
- The API significantly reduces perceived latency by starting audio synthesis before the complete text is available.
- Developers can build more natural voice interactions without having to implement complex buffering logic themselves.
