Prompting Guide · Gemini TTS

AI Prompt Generator

Build director‑style prompts for Gemini TTS that control not just what is said, but how it's delivered. Inspired by Google's official prompting guide, adapted for modern SaaS teams.

Why prompting matters

Gemini Native Audio TTS isn't a simple text reader. It uses a large language model that understands scenes, characters and performance notes.

Think of yourself as a director: define the audio profile, the scene, and the director's notes so the virtual voice talent knows exactly how to perform your script.

Prompt Builder

Define the director notes once, then reuse the generated prompt in your Gemini TTS API calls. This mirrors Google's recommended structure: audio profile, scene, director's notes and transcript.

Quality85%

Higher quality favors clean, broadcast‑ready reads over wild variation.

Creativity60%

More creativity lets the model improvise pacing and emphasis while staying on‑brief.

Live prompt

# AUDIO PROFILE

### DIRECTOR'S NOTES
Quality: Aim for a production‑ready read around 85% polish (clean, broadcast‑ready audio).
Creativity: Around 60% creative freedom – enough to feel human, but still on‑brief.
