Google 发布两款文本转语音模型 gemini-3.8-flash-tts 和 gemini-3.8-flash-lite-tts，内置超过 2,000 个预设音色。用户提供 30 秒音频样本即可创建自定义音色。API 支持定义多角色对话，每个角色可使用不同音色和语气指令。Simon Willison 用该工具生成一段 1 分 18 秒的双角色对话音频，耗时约 20 秒，成本 2.74 美分。
Gemini 3.8 TTS Playground
Tool: Gemini 3.8 TTS Playground Google released two new Gemini text-to-speech models today - gemini-3.8-flash-tts and gemini-3.8-flash-lite-tts . They come with a library of over 2,000 voices, plus the ability to create a custom voice with "just a 30-second audio sample of your voice or a voice you have the rights to use". I vibe coded this bring-your-own-key playground interface with GPT-6 Astra, taking advantage of the open CORS policy of the underlying Gemini API. A notable feature of the API is that it makes it easy to define a full conversation between multiple characters, each with different voices and voice style instructions. Here's a short demo clip of a conversation between two pelicans debating if they should move to the Pacifica Pier . I had Claude 4.5 Opus write the script and generate a URL to render it using the tool . Your browser does not support the audio element. It took ~20 seconds to generate 1m 18s of audio using Gemini 3.8 Flash TTS (not the cheaper Flash-Lite), at a cost of 2.74 cents. Tags: text-to-speech , gemini
