Google Gemini TTS Prompt Guide
Gemini 3.1 TTS performs your text — it doesn't just read it. Give it three things: WHO the voice is (persona), WHAT the scene feels like (direction), and HOW specific lines should land (inline emotion tags). Copy any recipe below as a starting point.
Recipe 01
Persona — character identity
Describe who the voice is. Age, background, vocal texture, speech habits. Gemini adapts vocal identity to match.
A weary war veteran in his late 60s. Gravelly voice from decades of smoking. Pauses before hard truths. Speaks slowly, with the weight of someone who's seen too much. Never raises his voice — but when he does, people listen.
Recipe 02
Voice Direction — scene atmosphere
Describe what the scene feels like. Location, mood, stakes. Gemini shifts pacing and energy like a voice director would.
A whispered confession in a candlelit library at midnight. Intimate, tense, afraid of being overheard. Every word carefully chosen. Long pauses between sentences — the listener needs time to absorb what was just said.
Recipe 03
Inline emotion tags — delivery shifts
Drop 80+ tags like [whispered], [excited], [sarcastic], [choking up] inline at the exact moment delivery should shift. Not a constant label — a shift marker.
[excited] Oh my god, we actually shipped it! [laughing] Six months of bugs and late nights and — [whispered] don't tell Marcus yet, he's still fixing the staging server.
Recipe 04
Audiobook narrator — full stack
Combine persona + direction + inline tags for book-length narration. This is what the Notevibes audiobook engine builds automatically from your manuscript.
Persona: A seasoned fantasy narrator in her 40s. Warm, measured, slightly theatrical without being campy. British RP accent. Comfortable with archaic dialogue and long descriptive passages. Scene: A quiet moment before battle. The calm before everything breaks. Reader must feel the weight of what's coming. Text: The dragon stirred. [slowly] Elara gripped her blade tighter. [whispered] "It knows we're here." [tense] The forest held its breath.
Recipe 05
Podcast host — conversational
For podcast intros, explainers, interviews. Casual persona, natural direction, light tags for emphasis.
Persona: A sharp, curious podcast host. Late 30s. Warm but direct. Thinks out loud. Comfortable with long sentences and parenthetical asides. Scene: Monday morning show open. Energy is friendly but focused — listeners are on their commute. Text: [warmly] Welcome back to the show. This week, [pauses] we're doing something different. [excited] We got the interview everyone said was impossible.
Recipe 06
Commercial / ad read
For ads, trailers, promotional videos. Punchy persona, high-stakes direction, strategic emphasis tags.
Persona: A confident, polished ad voice. Mid-30s. Sounds like they've used the product themselves. Friendly authority, never salesy. Scene: 30-second spot. Hook in 3 seconds, benefit in 10, call to action at the end. Text: [confident] Everyone says sleep is the foundation. [pauses] Few products actually earn that claim. [warm] Meet Luma. [excited] Try it free for 30 nights.
Recipe 07
Character voice — non-human
Gemini handles non-human voices via creative persona prompts and creative tags like [like an orc] or [robotic].
Persona: An ancient dragon who speaks in a voice that rumbles like distant thunder. Words come slowly, each one chosen with the precision of something that has lived ten thousand years. A faint growl underneath every syllable. Text: [growling] You think yourself brave, little flame. [slowly] I have watched empires rise and fall. [rumbling] I will watch yours do the same.
Recipe 08
E-learning / explainer
For courses, tutorials, training videos. Clear persona, patient direction, minimal tags.
Persona: A patient senior engineer explaining a concept to a junior dev. 30s. Clear, structured, comfortable with pauses. Never condescending — genuinely enjoys teaching. Scene: Screen recording voiceover. Matching the pace of someone reading and thinking along. Text: [clearly] So the first thing to understand is that JWT tokens are stateless. [pauses] What that means in practice is — the server doesn't need to remember anything about you. [warmly] Everything it needs is right there in the token.

Google text to speech, powered by Gemini 3.1 and Chirp 3 HD
Google’s text to speech has moved through several eras — Tacotron, WaveNet, Neural2 — each one a step closer to natural speech. The latest, Gemini 3.1 TTS from Google DeepMind, is a different kind of engine. Instead of a fixed voice reading your words, a multimodal model interprets the meaning, tone, and pacing of the text and performs it. Notevibes runs Gemini 3.1 TTS as its default expressive engine, so the Google voice you hear is the current generation, not a legacy vocoder.
The catch with Google’s own stack is that reaching those voices usually means a Google Cloud project, Vertex AI configuration, an API key, and billing setup — engineering work before you generate a single second of audio. Notevibes removes that layer. You paste your text, describe the voice, and download an MP3 or WAV. Alongside Gemini you also get Google Cloud’s Chirp 3 HD voices for clean, predictable narration across 30+ languages, so the two engines cover expressive character work and studio-neutral reads respectively.
Three layers of control, not one voice slider
Older Google TTS gives you a voice name and maybe a speaking rate. Gemini responds to direction. The first layer is persona — who the voice is: “a weary war veteran in his late 60s” or “a calm NPR host.” The second is scene direction — what the moment feels like: “a whispered confession in a candlelit library.” The third is inline emotion tags: drop [excited], [whispered], or [sarcastic] at the exact word where delivery should shift, and Gemini treats it as a performance cue rather than a constant setting.
Used together, these turn a flat read into something closer to a directed take. It’s the difference between a voice that pronounces your script correctly and one that acts it.
When to reach for Chirp 3 HD instead
Not every project wants a performance. For an e-learning module, an IVR prompt, or a product demo, you often want the same clean, neutral voice from start to finish. That’s what Chirp 3 HD voices are for — Google Cloud’s production neural voices, predictable and broadcast-clean, in more than 30 languages. Notevibes exposes both engines side by side, so you can match the voice to the job instead of forcing one model to do everything.
Where Google TTS through Notevibes fits
The heaviest users are people who want Google’s voice quality without Google’s plumbing: YouTubers narrating videos, course creators, and indie authors turning manuscripts into audiobooks. The audiobook workflow leans on Gemini directly — it builds a persona per character, assigns scene direction paragraph by paragraph, and inserts emotion tags at delivery shifts. Every render exports as MP3 or WAV with a full commercial license, so the audio is ready for YouTube, ads, courses, and client work.

Frequently Asked Questions
What is Google Gemini text to speech?
Google Gemini 3.1 TTS is a generative text-to-speech model from Google DeepMind — the same research team behind the Gemini multimodal models. Unlike older Google text to speech products (WaveNet, Tacotron, Neural2), Gemini generates speech end-to-end with a large multimodal model, so it understands meaning, emotion, and pacing from the text itself. Notevibes uses Google Gemini 3.1 TTS as its default expressive engine.
How is Google Gemini TTS different from Google Cloud Text-to-Speech (WaveNet / Neural2)?
Google Cloud Text-to-Speech WaveNet and Neural2 are neural vocoders — you pick a voice, and they read your text. Google Gemini 3.1 TTS is a generative model — you describe a persona and a scene, drop inline emotion tags, and the model performs the text. Gemini handles nuance, emotion, and character voices that WaveNet cannot. Notevibes exposes both: Gemini for expressive work, Chirp 3 HD for clean neutral narration.
Do I need a Google Cloud account or Google Text-to-Speech API key?
No. Notevibes handles all Google integration for you — no Google Cloud Console, no Vertex AI setup, no Google Text-to-Speech API quota management, no billing configuration. Paste your text, pick a Gemini voice, download the audio. Zero Google Cloud engineering required.
How do I use Google Gemini voices on Notevibes?
Open Notevibes, paste your text, and pick a voice. For Gemini 3.1 TTS you have three layers of control: (1) Persona — who the voice is (regal king, panicked sidekick, NPR host); (2) Voice Direction — what the scene feels like (whispered library, stadium hype); (3) Emotion Tags — inline 80+ tags like [whispered], [excited], [sarcastic] that shift delivery at specific points. Generate, preview, download.
What Google voices are available?
Notevibes gives you Google Gemini 3.1 TTS voices (Aoede, Charon, Kore, Puck, and more Gemini personas), plus Google Cloud Text-to-Speech Chirp 3 HD voices across 30+ languages. That is 550+ total AI voices powered by Google's voice technology — more than you would get by integrating Google Cloud TTS directly.
Can I use Google Gemini TTS audio for commercial projects on YouTube, ads, and courses?
Yes. All paid Notevibes plans include a full commercial license for audio generated with Google Gemini 3.1 TTS and Google Chirp 3 HD voices. Use it in YouTube videos, YouTube Shorts, TikTok, ads, e-learning courses, audiobooks, podcasts, commercials, and client work — no royalties, no revenue share.
Is Google Gemini text to speech free?
Notevibes has a free tier to try Google Gemini 3.1 TTS voices. Paid plans unlock full book-length generation, 80+ emotion tags, batch processing, commercial license, and priority access to Gemini capacity. You never pay Google Cloud TTS API costs directly — it is bundled into the Notevibes plan.
What audio formats and quality does Google Gemini TTS export?
Notevibes exports Google Gemini TTS and Google Chirp 3 HD audio as MP3 or WAV. You can adjust sample rate, speed, pitch, and volume before downloading. Gemini outputs are 24 kHz studio-quality — the same audio quality you'd get calling Google's model directly via Vertex AI.
Can Google Gemini TTS do character voices and audiobooks?
Yes — that is the primary use case. Notevibes' audiobook engine detects characters in your manuscript, builds a persona for each one, assigns scene-level voice direction per paragraph, and inserts inline emotion tags at delivery shift points. Then Google Gemini 3.1 TTS performs every paragraph as the right character. No other Google text to speech product supports this workflow out of the box.
