Gemini Text to Speech

☁ Cloud AI

Type or paste text. Gemini returns generated speech you can play or download. This is cloud AI, not the in-browser Kokoro voices.

Powered by Google Gemini. DevNestro is not an official Google product.

Uses the host TTS model (gemini-3.1-flash-tts-preview by default). Nothing is sent until you press Generate speech.

How it works

  1. Paste text, pick a voice, and optionally a delivery style.
  2. Confirm the text may be sent to Google Gemini. Generate speech calls the configured TTS model.
  3. Play or download the clip. Treat it as generated media, not a human recording.

FAQ

Is this processed locally?

No. The text is sent to Google Gemini. The local Text to Speech tool still runs in the browser if you want that path.

Why is Generate speech unavailable?

The host may be missing a Gemini key, the TTS model may be unavailable on the key, or the text rate limit was reached.

Read the original guide: Generate speech with Gemini and label it as generated audio.
