# Overview

> What Kova TTS is and how to choose between sync, streaming, and WebSocket.

Kova TTS is a low-latency text-to-speech API. You send text and a voice id; you get high-quality audio back. The API is available over three transports:

| Transport                                  | When to use                                                                                                                         | Time to first audio                                                           |
| ------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------- |
| **Sync HTTP** (`POST /v1/tts`)             | One-shot generation, batch jobs, when you want a single audio file at the end                                                       | Total generation time                                                         |
| **Streaming HTTP** (`POST /v1/tts/stream`) | Playing audio as it's generated for a single utterance                                                                              | First audio chunk in \~200ms                                                  |
| **WebSocket** (`WS /v1/tts/ws`)            | Interactive applications (voice agents, dialog systems) — feed text incrementally, generate multiple utterances over one connection | First audio chunk in \~200ms; subsequent utterances reuse the warm connection |

All three transports share the same voice catalog, the same authentication (`x-api-key` header), and the same billing.
