Google AI Studio voices for documentary narration: a strong free option
How Gemini's voices in Google AI Studio compare for documentary narration, how to direct them with plain language, and where they sit next to ElevenLabs.
Google AI Studio exposes Gemini's speech models, and they've become a serious option for narration: natural performance, plain-language direction, and a generous free tier. Here's how they hold up for long-form documentary work.
What they do well
- Direction in plain language. Tell the model to read calmly, pause before dates, or sound like a museum narrator, and it does.
- Natural rhythm. Less of the sing-song some TTS voices fall into.
- Multiple speakers if you need a second voice for quotes.
- Cost. The free tier covers a lot of narration; paid tiers are inexpensive.
Where to be careful
- Consistency across long scripts. Generate a chapter at a time with identical direction and check the seams.
- Register drift. Plain-language direction is powerful but loose; re-state the register at the top of every chapter.
- Word timing. As with any voice, you need timestamps per word to cut against. Transcribe the output with a word-level model, or use a pipeline that does it for you.

In Glisse
Glisse's narration step is voice-first and model-agnostic: the script is performed with direction, the words are timestamped, and the cut follows them. ElevenLabs' performed models are the default, with Gemini voices as an alternative, and you can record your own voice and pick the narrator per project.
