Replicate

Use Replicate's hosted TTS models as your provider.

Setup​

Environment variables (recommended for deployment):

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 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.
