About Google Text to Speech
Gemini 3.1 TTS is Google's most advanced text-to-speech model, created by Google DeepMind. Unlike earlier Google text to speech engines like WaveNet or Tacotron, Gemini generates speech end-to-end with the same multimodal model family that powers Gemini Flash — so the voice actually understands the meaning, tone, and pacing of your text. Notevibes runs Gemini 3.1 TTS as its default expressive engine and layers Google Cloud's Chirp 3 HD voices on top for broader language coverage. You type the text, describe the voice, and Google's model does the rest — no Google Cloud billing setup, no Vertex AI configuration, no Google Text-to-Speech API integration required.

Gemini Persona Voices
Define WHO the voice is — "a weary war veteran", "a hyperactive 12-year-old YouTuber", "a calm NPR host". Google's Gemini model adapts vocal identity to the persona description, unlocking voices no other Google TTS product can produce.
Gemini Voice Direction
Describe the scene — "a whispered secret in a candlelit library", "a stadium hype moment". Gemini 3.1 understands context and shifts pacing, energy, and atmosphere like a voice director.
Inline Emotion Tags
Drop 80+ emotion tags like [whispered], [excited], [sarcastic], [choking up] directly inline. Gemini treats them as delivery shift markers — natural performance changes, not constant labels.
Google Chirp 3 HD Voices
Google Cloud Text-to-Speech Chirp 3 HD voices — Google's production-grade neural voices in 30+ languages. Perfect when you need predictable, studio-clean narration instead of expressive Gemini output.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
