今天，我们向 Gemini 家族推出了两款新的文本转语音模型，将语音生成从静态预设转变为动态创意工作室。这些模型使创作者、开发者和企业能够创造更丰富、更具表现力的音频体验，同时提升 Gemini Notebook 和 Google Vids 等产品中的用户体验。

Gemini 3.8 Flash TTS：专为深度创意指导和角色设计而打造。使用自然语言提示从头创建全新的声音，为游戏、沉浸式有声书、播客和互动媒体中的角色赋予生命。逐行指导每一句表演台词，对表演提示、节奏、方言转换和背景回应进行精细控制。
Gemini 3.8 Flash-Lite TTS：专为大规模、高性价比的扩展而设计。针对高音量配音、音频内容创作以及具有语调、节奏和表现力细微差别精细控制的表达性语音代理进行了优化。

这些模型补充了我们快速增长的 Gemini Audio 家族，紧随 3.5 Live Translate、3.5 Transcribe、3.8 Live 和 3.8 Live Extended Thinking 之后。

创建并自定义您自己的声音

从 30 个原始声音扩展到无限的声音库。无论您需要一个完全原创的角色声音还是一个一致的品牌大使，我们的 3.8 Flash TTS 模型都能提供完整的语音工作室支持。这使您能够为每个时刻创建并使用富有表现力、听起来自然的声音，同时赋能开发者和企业轻松构建自定义音频体验。

生成式语音设计：借助 Gemini 3.8 Flash TTS，通过自然语言提示定制角色、口音和声音特征，覆盖 100 多种语言和方言，从头开始创建专属声音——无论您是在塑造一条喷火的戏剧性巨龙，还是在创作一位具有独特区域节奏的魅力旁白。

广阔的声音库：访问 2,000 多个生产就绪的声音，涵盖广泛的语言——包括墨西哥西班牙语、魁北克法语和苏格兰英语等地区变体。
声音复制：仅凭您自己或您有权使用的声音的 30 秒音频样本，即可重现一致的语音特征，并由内置的同意验证、SynthID 水印和 C2PA 凭证提供支持，以保护开发者和他们的语音人才。
保存与扩展：保存并管理您设计的自定义声音，以确保在持续项目中保持一致的性能并将漂移降至最低。
声音混音：即将推出，从我们的声音库中选择一个声音，并微调音色、音高、节奏和口音。使用提示来调整特征（例如，“添加微妙的美国南部口音”或“柔和语气”）。

逐行指导表演

一旦您选择了声音，这两款 TTS 模型都让您能够精确控制每句台词的呈现方式。

获取专为全球规模构建的富有表现力的高质量语音生成

Gemini 3.8 Flash TTS 提供领先的语音定制能力，在 Hume AI 的 Voice Design Benchmark（71.4）上总体排名第一，并在口音建模方面（60.8）同样领先。

Gemini 3.8 Flash TTS 和 Gemini 3.8 Flash-Lite TTS 在确保可靠性的同时实现了真正富有表现力的表演，分别在 Hume AI 的总体质量指数中占据第一和第二的位置。与 Gemini 3.1 Flash TTS 相比，该模型在长篇幅内容和双说话人剧本控制等广泛用例方面显示出重大改进。

在 Voice Arena 的盲测人类偏好评估中，Gemini 3.8 Flash 和 Flash-Lite TTS 在包括日语、巴西葡萄牙语、越南语、现代标准阿拉伯语（MSA）、墨西哥西班牙语和印地语在内的关键全球语言中，在竞争对手中占据领先地位。凭借对 100 多种语言的支持，这些模型赋能创作者、开发者和企业，在全球范围内构建高质量的_multilingual_语音体验。

以信任、同意和透明为基础进行构建

我们构建了严格的保障措施，以帮助保护声音人才、尊重身份并确保内容透明，从而打造我们的语音创建和复制能力。对于语音复制，我们的系统利用同意验证：在创建声音之前，用户必须提供来自声音所有者的、与参考说话人匹配的口头同意录音。

更广泛地说，由我们的 Gemini Audio 模型生成的每个音频片段都带有 SynthID 水印。这种不可见的水印直接编织到音频输出中，确保 AI 生成的语音可被检测，从而帮助防止虚假信息。有关我们安全与责任方法的更多详情，请参阅模型卡片。

试用我们的全新 Google AI Studio 音频游乐场

从今天开始，开发者可以在 Google AI Studio 中体验这些新的语音生成能力。该工具构建为语音设计工作区，您可以从零开始提示全新的声音身份或复制您自己的声音

Today, we’re introducing two new text-to-speech models to the Gemini family, transforming voice generation from static presets into a dynamic creative studio. These models enable creators, developers, and enterprises to create richer, more expressive audio experiences, while enabling improved user experiences in products like Gemini Notebook and Google Vids.

Gemini 3.8 Flash TTS: Built for deep creative direction and character design. Create entirely new voices from scratch using natural language prompts to bring characters to life across gaming, immersive audiobooks, podcasts, and interactive media. Direct every performance line by line with granular control over acting cues, pacing, dialect shifts, and backchanneling.
Gemini 3.8 Flash-Lite TTS: Built for high-volume, cost-efficient scale. Optimized for high-volume dubbing, audio content creation, and expressive voice agents with fine-grained control over tone, pacing, and expressive nuance.

These models complement our fast-growing Gemini Audio family, following 3.5 Live Translate, 3.5 Transcribe, 3.8 Live, and 3.8 Live Extended Thinking.

Create and customize your own voices
00:00

Scale up from 30 original voices to an infinite library. Whether you need an entirely original character voice or a consistent brand ambassador, our 3.8 Flash TTS model powers a full vocal studio. This enables you to create and use expressive, natural-sounding voices for every moment, while empowering developers and enterprises to easily build custom audio experiences.

Generative voice design: With Gemini 3.8 Flash TTS, create bespoke voices from scratch by customizing role, accent and voice characteristics across more than 100 languages and dialects using natural language prompting — whether you're bringing a dramatic, fire-breathing dragon to life or crafting a charismatic narrator with a distinct regional cadence.

Expansive voice library: Access 2,000+ production-ready voices with broad language coverage — including regional varieties like Mexican Spanish, Quebec French, and Scots English.
Voice replication: Recreate consistent vocal profiles from just a 30-second audio sample of your voice or a voice you have the rights to use, backed by built-in consent verification, SynthID watermarking, and C2PA credentials to protect both developers and their vocal talent.
Save and scale: Save and manage the custom voices you designed to ensure consistent performance and minimal drift across ongoing projects.
Voice remixing: Coming soon, pick a voice from our voice library and fine-tune timbre, pitch, pace, and accent. Use prompts to dial in characteristics (e.g. “add subtle Southern US accent” or “soften the delivery”).
Direct the performance, line by line

Once you've selected your voices, both TTS models give you precise control over how each line is delivered.

Direct performance line by line: Write your own stage directions or let Gemini steer delivery with natural script cues — from a calm customer service agent to a whispered suspense scene.

Long-form generation: Maintain high voice quality, natural pacing, and character timbre across hours of continuous audio with minimal speaker drift — ideal for podcasts and audiobooks.
Native two-speaker scene staging: Direct multi-turn conversations seamlessly from a single script —whether for a podcast or dramatic storytelling—while keeping both voices distinctly separated with natural conversational turn-taking.
Scripted vocal bursts & backchanneling: Add realistic conversational texture using non verbal cues (like , , and active-listening interjections (like |mhm| or|yeah|) for precise comedic timing and reaction beats.

Get expressive high-quality speech generation built for global scale

Gemini 3.8 Flash TTS delivers leading voice customization capabilities, securing the #1 overall spot on Hume AI’s Voice Design Benchmark (71.4) and also leading in accent modeling (60.8).

Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS enable truly expressive performances without sacrificing reliability, also securing the #1 and #2 spots respectively on Hume AI’s Overall Quality Index. The model shows major improvements on a wide range of use cases such as long-form content and dual-speaker screenplay control compared to Gemini 3.1 Flash TTS.

In blind human preference evaluations on Voice Arena, Gemini 3.8 Flash and Flash-Lite TTS secure top positions amongst competitors in key global languages, including Japanese, Brazilian Portuguese, Vietnamese, Modern Standard Arabic (MSA), Mexican Spanish and Hindi. With support for over 100 languages, these models empower creators, developers, and enterprises to build high-quality, multilingual voice experiences worldwide.

Build with trust, consent, and transparency

We built our voice creation and replication capabilities with strict safeguards to help protect voice talent, respect identity, and ensure content transparency. For voice replication our system leverages consent verification: users must provide a verbal consent recording from the voice owner that matches the reference speaker before a voice can be created.

More broadly, every audio clip generated by our Gemini Audio models is watermarked with SynthID. This imperceptible watermark is woven directly into the audio output, ensuring AI-generated speech remains detectable to help prevent misinformation. For more details on our approach to safety and responsibility, review the model card.

Try our new Google AI Studio audio playground

Starting today, developers can experience these new speech generation capabilities in Google AI Studio. Built like a voice design workspace, you can prompt entirely new vocal identities from scratch or replicate your own voice

, then bring them directly into a dual-speaker screenplay editor to direct line-by-line delivery.

Try voice replication in Google AI Studio.

Deploy high-performance voice interfaces with ease

By using the Gemini API, developer platforms such as Agora, LiveKit, Pipecat, Vercel enable developers to build and deploy high-performance speech generation experiences with ease.

We’re partnering with companies like Figma, HeyGen, Linguana, Wondercraft, 99.co, and Ollang, who are integrating our latest TTS models to help accelerate global dubbing, localize media with nuanced regional accents, and power conversational voice agents at scale.
