## Text to Speech FAQs

### What languages do you support?

We support English (both British and American) and we plan to launch additional languages in 2025.

### Can I control voice speed, pitch, or emphasis?

Not yet. The API outputs natural speech with prosody driven by the text content. Fine-grained voice control features may be added in future releases.

### How much latency should I expect?

The initial audio chunk typically returns in less than 200ms, with subsequent audio chunks returning faster than real time.

### Is there a streaming API for real-time generation?

The API supports streaming audio output (you can play audio as it arrives), but not full bidirectional streaming. We plan to add support for this in the future.

### Can I deploy this in my own environment?

Yes! The text to speech API can be consumed via our managed service or deployed in your own environment. To learn more about on-premises deployment options please [contact our sales team](https://www.speechmatics.com/speak-to-sales).
