Gemini TTS transforms written scripts into playable and downloadable WAV speech files directly in your browser. It supports generating audio with a single voice for readings or assigning lines to two distinct speakers for conversational dialogue. The studio provides access to Gemini 3.8 Flash and Flash Lite models, along with 30 preset voices, offering controls for accent, style, and pace. Users can enhance delivery by adding short vocal cues like <laugh> or by providing voice and scene descriptions in advanced settings. A preview feature allows listening to voices before generation, and all finished audio takes are stored in a personal library.
How to create speech with Gemini TTS
Users begin by selecting either the Gemini 3.8 Flash model for expressive delivery or Flash Lite for more straightforward read-aloud tasks, considering their respective credit rates. They can then browse through 30 preset voices, each with a neutral sample, and choose one or two for their script. The platform allows users to type or paste text, adjusting accent, style, and pace, and inserting vocal cues like <sigh> or <short pause>. Optional voice and scene descriptions provide additional context for the AI model. After checking estimated credits, the speech can be generated, played in the studio, or downloaded as a WAV file, with all completed takes stored in a personal library.
