What is Gemini 3.8 Flash-Lite TTS?

Gemini 3.8 Flash-Lite TTS is Google’s efficiency-focused text-to-speech model for generating expressive audio at high volume. It is positioned for applications where scalability and cost efficiency are important, including dubbing, localization, automated content production, and conversational voice systems. The model gives users detailed control over speech characteristics such as tone, pacing, delivery, and expressive nuance. Creators and developers can direct individual lines using script instructions to produce performances ranging from straightforward narration to more expressive dialogue. Long-form generation is designed to maintain natural pacing, audio quality, and stable speaker characteristics over extended recordings such as podcasts and other continuous content. Gemini 3.8 Flash-Lite TTS also supports native two-speaker scene staging, allowing a single script to generate structured conversations with distinct speakers and natural turn-taking. Nonverbal performance cues including laughs, sighs, gasps, and conversational backchanneling can be incorporated to add realistic texture to generated speech. With support for more than 100 languages, the model can be used to create multilingual audio experiences and localized content for audiences across different regions. Google reports that Gemini 3.8 Flash-Lite TTS performs strongly in human preference evaluations across languages including Japanese, Brazilian Portuguese, Vietnamese, Modern Standard Arabic, Mexican Spanish, and Hindi. Generated audio from Gemini Audio models includes SynthID watermarking, providing an imperceptible signal that can help identify AI-generated speech. Gemini 3.8 Flash-Lite TTS is available through Google AI Studio and the Gemini API, is integrated into Google Vids, and is planned for enterprise API access through Gemini Enterprise.
