A New Generation of Voice: Gemini 3.8 Flash TTS for Voice AI Developers
Blog post from Agora
Agora highlights Gemini 3.8 Flash TTS and Flash-Lite TTS as text-to-speech models designed to give developers greater control over speech delivery, including emotion, pace, character, accent, and changes in tone during a conversation. Flash TTS offers a library of more than 20,000 voices across languages and regions while retaining existing named voices, enabling teams to select voices suited to different audiences and applications. The models are intended to improve voice consistency during extended interactions and support more natural multi-speaker dialogue through realistic pacing, breathing, and turn-taking. Agora suggests these capabilities could support customer-service agents, educational tools, interactive stories, game characters, and regionally localized voice applications, with the goal of making real-time AI voice experiences feel more natural and engaging.
