Test Voice Narrations Instantly in the AI Studio Sandbox
Experiment with the voice library and features without writing any code.
Use the Google AI Studio sandbox to preview voices and test prompt-based audio controls for free before full-scale implementation.
The Scenario
You want to see if the new Gemini voices are suitable for your project before spending time writing code or integrating APIs.
Before & after
Normally, you would have to write code, set up an API environment, and manage billing before hearing a single word, taking 20–40 minutes.
Open Google AI Studio, select the 'Generate Speech' feature, and paste your text to hear the result for free in about 1 minute.
The Prompt
(In Google AI Studio Speech Sandbox) Paste your text here: [PASTE TEXT]. Select Voice: [SELECT FROM LIBRARY]. Instructions: Make the speaker sound [DESIRED EMOTION].
Google AI Studio provides a 'sandbox' specifically for Gemini 3.1 Flash TTS where users can test different voices and settings before committing to developer implementation.
