# overview

> the rumik silk text-to-speech API.

silk is rumik AI's text-to-speech API. it turns text into natural, expressive
speech over a simple HTTP call or a real-time WebSocket stream. audio comes back
as 24 kHz mono PCM.

pick the model that fits your use case:

    preset studio voice.

## audio format

every response is **24 kHz, mono, signed 16-bit PCM**. the HTTP endpoint wraps it
in a WAV container (`audio/wav`); the WebSocket stream sends raw PCM chunks.
