AI Gateway has started supporting Google's Gemini 3.8 Flash-Lite TTS and Gemini 3.8 Flash TTS models. Both models convert text to speech in over 100 languages and offer long-form narration, delivery control, and two-person dialogue features.
Gemini 3.8 Flash-Lite TTS is optimized for large-scale voice generation and includes controls for tone, speed, and line-by-line delivery. In contrast, Gemini 3.8 Flash TTS additionally supports voice and character design features, including acting directions, accents, and conversational responses, through natural language prompts.
Users can perform voice generation via AI Gateway's unified API, with support for usage and cost tracking per request. Setting up routing rules and using Bring Your Own Key (BYOK) are also possible.
