Gêmeos 3.1 Flash TTS

Gêmeos 3.1 Flash TTS. O Google lançou hoje o Gemini 3.1 Flash TTS, um novo modelo de conversão de texto em fala que pode ser direcionado por meio de prompts.

É apresentado através da API padrão do Gemini usando gemini-3.1-flash-tts-preview como ID do modelo, mas só pode gerar arquivos de áudio.

O guia inspirador é surpreendente, para dizer o mínimo. Aqui está o exemplo de prompt para gerar apenas algumas frases curtas de áudio:

# AUDIO PROFILE: Jaz R.
## "The Morning Hype"

## THE SCENE: The London Studio
It is 10:00 PM in a glass-walled studio overlooking the moonlit London skyline, but inside, it is blindingly bright. The red "ON AIR" tally light is blazing. Jaz is standing up, not sitting, bouncing on the balls of their heels to the rhythm of a thumping backing track. Their hands fly across the faders on a massive mixing desk. It is a chaotic, caffeine-fueled cockpit designed to wake up an entire nation.

### DIRECTOR'S NOTES
Style:
* The "Vocal Smile": You must hear the grin in the audio. The soft palate is always raised to keep the tone bright, sunny, and explicitly inviting.
* Dynamics: High projection without shouting. Punchy consonants and elongated vowels on excitement words (e.g., "Beauuutiful morning").

Pace: Speaks at an energetic pace, keeping up with the fast music.  Speaks with A "bouncing" cadence. High-speed delivery with fluid transitions — no dead air, no gaps.

Accent: Jaz is from Brixton, London

### SAMPLE CONTEXT
Jaz is the industry standard for Top 40 radio, high-octane event promos, or any script that requires a charismatic Estuary accent and 11/10 infectious energy.

#### TRANSCRIPT
(excitedly) Yes, massive vibes in the studio! You are locked in and it is absolutely popping off in London right now. If you're stuck on the tube, or just sat there pretending to work... stop it. Seriously, I see you.
(shouting) Turn this up! We've got the project roadmap landing in three, two... let's go!

Aqui está o que obtive usando esse prompt de exemplo:

Então modifiquei para dizer “Jaz é de Newcastle” e “… requer um sotaque carismático de Newcastle” e obtive este resultado:

Aqui está Exeter, Devon, para garantir:

Eu fiz com que o Gemini 3.1 Pro codificasse esta UI para testá-la:
