    "about": "Gemini 3.8 Flash TTS is intended for expressive narration and long-form storytelling. Google highlights audiobooks, multi-speaker dialogues and voice consistency over extended passages. Speech control covers emotional delivery, rhythm and pronunciation, including regional accents and dialects.\n\n### Voices and languages\n\nThe model is described as supporting **130 languages**, including Russian. **30 preset voices**, an expanded library, creation of a voice identity from a description and reproduction of a voice from a sample are available. These capabilities allow timbre and performance character to be selected for particular material.\n\nDialogue lines are associated with speakers. One multi-speaker request can use no more than two preset voices. For voices created from a description or sample, lines are synthesized separately; having such a voice does not make it another preset voice within a multi-voice request.\n\n### Text and delivery control\n\nInput is **text**, and output **audio**. Limits are **8192 input tokens** and **16,384 output tokens**. Text is treated as a spoken line; style description and the selected speaker are specified separately. This separates the words to be spoken from instructions about how to read them.\n\nStyle covers emotion, pace, volume and prosody. Brief events such as laughter, sighs and pauses are specified with special audio tags within the line. These tags control the performance rather than serving as ordinary words to be read aloud.\n\n### Audio formats and capabilities\n\nOrdinary generation returns **WAV** by default. Streaming uses **headerless PCM** by default. Original parameters are **24 kHz, one channel and 16 bits**. PCM, mu-law and A-law are also provided. Context caching and batch processing are supported. The specific file format and available settings depend on the selected speech method.\n\nThe model specializes in speech creation. Function calling, code execution, file search, search grounding, Google Maps, image generation, structured text responses, Thinking and URL contents are not supported. Consistent voice and controllable expressiveness are the model's stated aims, not a promise of perfect pronunciation in every line.",
