[Core Function] Gemini 3.8 Flash Lite TTS is Google's text-to-speech model for low-latency speech generation. [Strengths] Single-speaker synthesis, two-speaker dialogue, 101 languages, per-turn style control, and WAV output (24 kHz mono PCM). [Best For] Bulk narration, voice-agent responses, read-aloud features, and multilingual dialogue. [Limitations] Do NOT use this for streaming, voice creation, music generation, or audio, image, or video input. Dialogue requires exactly two speakers with prebuilt or extended-library voices; designed or replicated voices are limited to single-speaker synthesis. Combined text and style must stay within 8,192 Unicode characters. [Routing] Choose Flash Lite for latency and cost efficiency; choose Gemini 3.8 Flash TTS for expressive delivery and broader language coverage.
