Description

Gemini 3.8 Flash-Lite TTS is an expressive text-to-speech model from Google optimized for high-volume, cost-efficient speech generation. It is designed for workloads such as global dubbing, large-scale audio content production, localization, and conversational voice agents. Users can control characteristics such as tone, pacing, emphasis, and expressive nuance to shape how generated speech is delivered. Line-by-line direction allows scripts to include performance instructions and natural speech cues rather than producing uniformly spoken narration. The model supports long-form generation and is designed to preserve voice quality, natural pacing, and character consistency across extended audio. Native two-speaker staging allows developers and creators to generate multi-turn conversations while keeping speakers distinct and maintaining natural turn-taking. Scripted cues can introduce laughs, sighs, gasps, and listening responses such as “mhm” or “yeah” to make dialogue more conversational. Gemini 3.8 Flash-Lite TTS supports more than 100 languages and is designed for multilingual audio experiences at global scale, while generated Gemini Audio output includes SynthID watermarking for transparency. Developers can access the model through Google AI Studio and the Gemini API, with integration into Google Vids and planned API availability through Gemini Enterprise.

Description

StepAudio 3 represents the latest advancement in StepFun's audio model series, designed to comprehend, produce, and engage through various auditory forms including voice, sound, and music.
