Google: Gemini 3.8 Flash Lite TTS

Gemini 3.8 Flash Lite TTS is a text-to-speech model from Google and the fast, high-throughput member of the 3.8 TTS family alongside [Gemini 3.8 Flash TTS](https://openrouter.ai/google/gemini-3.8-flash-tts). It is suited for conversational voice-agent pipelines, high-volume read-aloud, and voice replication workloads where latency and cost matter more than maximum expressiveness. It accepts the same speech configuration as [Gemini 3.1 Flash TTS Preview](https://openrouter.ai/google/gemini-3.1-flash-tts-preview), including the 30 prebuilt studio voices, and supports Google's Voice Design and Voice Replication through `voice_...` identifiers.
