You can now customize Siri’s pace and expressivity in the latest iOS 27 beta

你现在可以在最新的 iOS 27 测试版中自定义 Siri 的语速和表现力

With the latest iOS 27 developer beta, Apple is giving testers an early look at one of the upcoming improvements to its AI-powered Siri: the ability to adjust how quickly and expressively the AI assistant speaks. 随着最新的 iOS 27 开发者测试版的发布，苹果让测试人员提前体验了其 AI 驱动的 Siri 即将迎来的一项改进：能够调整 AI 助手的语速和说话的表现力。

In iOS 27 beta 3, out today, Apple has enabled the voice controls for “Pace” and “Expressivity” that were previously labeled as “Coming soon” in the first developer beta releases. The update is part of Apple’s broader effort to make Siri feel more natural and personal, as it rebuilds the assistant around generative AI. 在今天发布的 iOS 27 beta 3 中，苹果启用了“语速”（Pace）和“表现力”（Expressivity）的语音控制功能，这些功能在最初的开发者测试版中曾被标记为“即将推出”。此次更新是苹果让 Siri 感觉更自然、更个性化这一宏大计划的一部分，因为苹果正围绕生成式 AI 重建该助手。

Like ChatGPT and others offering voice AI assistants, letting users customize how the AI sounds is an important aspect in helping connect people with the new technology. However, ChatGPT’s voice-customization options allow users to go even further, as the ability to adjust the AI’s warmth and enthusiasm was rolled out in December 2025, alongside options to configure the base style and tone. The latter lets users adjust OpenAI’s assistant to be more friendly, professional, candid, or quirky, among other styles. This is reflected not only in how ChatGPT speaks, but also in how it presents information to the user. 与 ChatGPT 及其他提供语音 AI 助手的平台一样，允许用户自定义 AI 的声音是帮助人们与新技术建立联系的重要一环。不过，ChatGPT 的语音自定义选项允许用户进行更深度的设置，例如 2025 年 12 月推出的调整 AI 温暖度和热情度的功能，以及配置基础风格和语气的选项。后者允许用户将 OpenAI 的助手调整得更友好、专业、坦率或古怪等多种风格。这不仅体现在 ChatGPT 的说话方式上，也体现在它向用户呈现信息的方式上。

First introduced at Apple’s Worldwide Developers Conference (WWDC 26) in June, Siri’s voice controls let users personalize their Siri experience beyond just choosing a male- or female-sounding assistant. Now beta testers will be able to switch between a range of voices with different accents, and then use sliders to change how slowly or quickly Siri speaks and how much human-like emotion its voice conveys. As you make the adjustments, Siri will practice saying some common things, like “You have one new message,” so you can get a sense of how the different voices sound. Siri 的语音控制功能首次在 6 月份的苹果全球开发者大会（WWDC 26）上亮相，它让用户能够超越单纯选择男性或女性声音，从而实现个性化的 Siri 体验。现在，测试人员可以在一系列带有不同口音的声音之间进行切换，并使用滑块来改变 Siri 的语速以及其声音所传达的人类情感程度。当你进行调整时，Siri 会练习说一些常用语，例如“你有一条新消息”，这样你就能直观地感受到不同声音的效果。

The AI version of Siri is deeply integrated across the updated version of iOS, where it will allow iPhone owners to start conversations by speaking, swiping down from the Dynamic Island at the top of the screen and typing, tapping on the phone’s side button, or even by using the brand-new stand-alone Siri app. AI 版本的 Siri 与更新后的 iOS 系统深度集成，iPhone 用户可以通过语音、从屏幕顶部的灵动岛向下滑动并输入文字、点击手机侧边按钮，甚至使用全新的独立 Siri 应用来开启对话。

Other, more minor updates are also rolling out with iOS 27 beta 3, including an updated Reminders app icon. (We should note some people on X are also reporting losing access to the new Siri after updating, or seeing their phone again begin indexing their data — typically, the first step in optimizing Siri AI for search.) iOS 27 beta 3 还带来了一些较小的更新，包括更新后的“提醒事项”应用图标。（我们需要指出的是，X 平台上也有一些用户报告称更新后无法使用新版 Siri，或者发现手机重新开始索引数据——这通常是优化 Siri AI 搜索的第一步。）
