Strengths

Higher-quality Google voices

Use Pro TTS when the line needs to carry emotion, pacing, and a premium finish.

Stronger delivery

Better prosody and pacing than the Flash tier, closer to a natural read.

Multi-speaker ready

Pass two speakers for short dialogues with distinct voices in one request.

Shared voice picker

Same 30 Gemini voices with filters for character, language hints, and previews.

Workflow

A polished voice delivery

Write the line like a performance cue, pick the voice, and re-run until the read matches the scene.

  1. 1

    Draft on Flash first

    Use Flash TTS to settle the line and voice choice before paying for a Pro render.

  2. 2

    Upgrade to Pro

    Switch to Pro for the final delivery when pacing and quality matter.

  3. 3

    Iterate on the line

    Small punctuation and phrasing changes will shift the read more than voice swaps.

Questions

When should I use Pro over Flash?

Use Pro when the voice output will ship as final audio. Use Flash for fast drafts and iteration.

Can I use custom voices?

Not yet. Pro TTS uses the 30 Gemini prebuilt voices. Custom voice cloning is on the roadmap.

Does Pro support multiple speakers?

Yes. Provide a speakers array with two distinct voices and labeled lines in the text.
