Use Replicate's hosted TTS models as your provider.

## Setup

**Environment variables (recommended for deployment):**

```env
API_KEY=r8_...
NEXT_PUBLIC_DEFAULT_TTS_PROVIDER=replicate
NEXT_PUBLIC_DEFAULT_TTS_MODEL=alphanumericuser/kokoro-82m:89b6fa84e4fa2dd6bd3a96be3e1f12827a3516c9fda8fddbac7a0be131c9a6f5
```

**Or in-app via Settings -> TTS Provider:**

1. Set provider to `Replicate`.
2. Enter your `API_KEY`.
3. Choose a model and voice.

Settings modal values override env vars. See [TTS Providers](../tts-providers) for how the two layers interact.

## Notes

- Built-in Replicate models:
  - `alphanumericuser/kokoro-82m:89b6fa84e4fa2dd6bd3a96be3e1f12827a3516c9fda8fddbac7a0be131c9a6f5`
  - `google/gemini-3.1-flash-tts`
  - `minimax/speech-2.8-turbo`
  - `qwen/qwen3-tts`
  - `inworld/tts-1.5-mini`
- You can also choose `Other` and enter any Replicate model ID (for example `owner/model-name` or `owner/model-name:version`).
- Native model speed is not available on all Replicate models; OpenReader hides/disables native speed controls where unsupported.
- TTS requests are sent from the server, not the browser. The API key is never exposed to clients.
