If you have trouble reading text, seeing specific colors, or making out things on the screen, Chrome OS has accessibility features bursting at the seams designed to help you. You can manage them individually from the system menu or the Settings app to use on everyday tasks.

如果您在阅读文字，查看特定颜色或在屏幕上看不清东西时遇到问题，Chrome操作系统会在旨在帮助您的接缝处突显辅助功能。 您可以从系统菜单或“设置”应用单独管理它们，以用于日常任务。

如何查看辅助功能 (How to View Accessibility Features)

The easiest way to enable/disable each accessibility feature without having to open up the Settings app each time is directly from the system menu. This is off by default, so you’ll need to toggle it on first.

无需每次都打开“设置”应用程序而启用/禁用每个可访问性功能的最简单方法是直接从系统菜单中进行。 默认情况下此功能处于关闭状态，因此您需要先将其打开。

First, click on the clock to open the system menu and notification tray; then click on the Settings icon.

首先，点击时钟以打开系统菜单和通知托盘； 然后点击设置图标。

Scroll to the bottom and click “Advanced.”

滚动到底部，然后单击“高级”。

Scroll a little bit further until you see the Accessibility section, and then toggle “Always show accessibility option in the system menu” to the On position.

进一步滚动直到您看到“辅助功能”部分，然后将“在系统菜单中始终显示辅助功能选项”切换到“打开”位置。

The next time you open the system menu, the Accessibility button will be available. Click on it to open the expanded view.

下次打开系统菜单时，“辅助功能”按钮将可用。 单击它以打开展开的视图。

You can click on any of the features available in this menu to enable them. If you’re unsure of what a particular feature does, however, we have you covered—read on to get the full details of what each of these does.

您可以单击此菜单中的任何可用功能以启用它们。 但是，如果您不确定某个特定功能的功能，我们将为您提供帮助-请继续阅读以获取每个功能的完整详细信息。

文字转语音功能 (Text-to-Speech Features)

()

Both features under this section focus on using Google’s text-to-speech (TTS) engine to take content from the active window, then read it back to you. Chromebooks come equipped with a free built-in screen reader that allows you to hear what’s on your display.

本节中的两个功能都着重于使用Google的语音合成(TTS)引擎从活动窗口中获取内容，然后将其读回给您。 Chromebook配备了免费的内置屏幕阅读器，可让您听到显示器上显示的内容。

ChromeVox：Chrome操作系统的屏幕阅读器 (ChromeVox: Chrome OS’ Screen Reader)

ChromeVox is a free screen reader built into every Chromebook that helps visually impaired people use Chrome OS. It’s built solely on web technologies (HTML5, CSS, and JavaScript), making it a fast and versatile way to navigate Chrome OS. It comes pre-installed in all current versions of Chrome OS, so all you need to do is enable it and it starts to read out everything on the screen.

ChromeVox是每台Chromebook内置的免费屏幕阅读器，可帮助视障人士使用Chrome操作系统。 它完全基于Web技术(HTML5，CSS和JavaScript)构建，使其成为浏览Chrome操作系统的快速且通用的方法。 它已预安装在所有当前版本的Chrome操作系统中，因此您只需启用它即可开始读取屏幕上的所有内容。

You can turn on ChromeVox at any time by pressing Ctrl + Alt + z to hear a voice read aloud content from your cursor’s current position. If you’re using a tablet running Chrome OS, press and hold the Volume Up + Volume Down buttons for five seconds. You’ll hear a chime sound and a ChromeVox bar will appear at the top of your screen, notifying you it is enabled.

您可以随时按Ctrl + Alt + z来打开ChromeVox，以听到语音从光标当前位置朗读内容。 如果您使用的是运行Chrome操作系统的平板电脑，请按住“提高音量+降低音量”按钮5秒钟。 您会听到提示音，并且ChromeVox栏将出现在屏幕顶部，通知您已启用。

要禁用ChromeVox，请重复硬件快捷方式，然后会发出提示音，通知您现在已关闭。

选择要朗读的文本 (Choose Text to Have Read Aloud with Select-to-Speak)

Select-to-Speak works similarly to ChromeVox, but instead of reading full pages, it only reads text that you select. When enabled in System Menu > Accessibility > Select-to-Speak, an icon appears next to the system tray.

语音选择功能与ChromeVox相似，但是它不会读取整页内容，而只会读取您选择的文本。 在“系统菜单”>“辅助功能”>“选择说话”中启用后，系统托盘旁边会出现一个图标。

Once enabled, Select-to-Speak offers a few ways to select which text you want to hear:

启用“选择说话”功能后，您可以通过以下几种方式选择要收听的文本：

Press and hold the Search key + select a line of text.按住搜索键+选择一行文本。 Press and hold the Search key + drag the pointer over an area of the screen.按住搜索键+将指针拖动到屏幕区域上。 Highlight the text and press Search+S.突出显示文本并按Search + S。 Select the Select-to-speak icon from the taskbar, then select a line of text or drag the pointer over an area of the screen.从任务栏中选择“讲话选择”图标，然后选择一行文本或将指针拖动到屏幕区域上。 On a touchscreen: Tap Select-to-speak. Then tap a line of text or drag your finger over an area of the screen.在触摸屏上：点击“选择讲话”。 然后点击一行文本或在屏幕区域上拖动手指。

Select-to-Speak surrounds the selected text in a pink border and highlights the word currently being read so that you can follow along easily with the voice.

“语音朗读”将所选文本包围在粉红色边框中，并突出显示当前正在阅读的单词，因此您可以轻松地跟随语音。

You can stop Select-to-Speak at any time while it’s reading by pressing either the Search key or Ctrl.

您可以在阅读时随时通过按搜索键或Ctrl停止“朗读”。

更改语言或语音设置 (Change the Language or Voice Settings)

If you don’t like the way TTS is speaking to you, it’s easy to change. You can alter its voice, pitch, or language without hurting its feelings. Head back to Settings > Manage Accessibility Features and click “Text-to-Speech voice settings” under the Text-to-Speech section.

如果您不喜欢TTS与您交谈的方式，很容易进行更改。 您可以更改其声音，音调或语言，而不会损害其感觉。 返回“设置”>“管理辅助功能”，然后单击“文本到语音”部分下的“文本到语音的语音设置”。

Inside you’ll find a plethora of voice altering options to give the TTS a personal touch for your ear. You can even change the speech engine used for playback.

在内部，您会发现大量的语音更改选项，使TTS的耳朵更具个性。 您甚至可以更改用于播放的语音引擎。

显示功能 (Display Features)

For anyone with trouble seeing what’s on the screen, Google has you covered with a set of tools built to help make your screen more viewable. Whether you need to use high contrast mode to make text easier to read or an on-screen magnifier to increase the size of everything, your Chromebook comes equipped with it all.

对于任何无法查看屏幕内容的人，Google都提供了一系列工具来帮助您使屏幕更清晰可见。 无论您需要使用高对比度模式以使文本更易于阅读，还是需要使用屏幕放大镜来放大所有内容，Chromebook都具备了所有功能。

通过高对比度模式使文本更易于阅读 (Make Text Easier to Read With High Contrast Mode)

High contrast mode lets you use your Chromebook with inverted colors, designed to make it easier to read text on your screen. When enabled, white becomes black, black becomes white, blue becomes orange, orange becomes blue, etc.

高对比度模式可让您以反色使用Chromebook，旨在使您更轻松地阅读屏幕上的文字。 启用后，白色变为黑色，黑色变为白色，蓝色变为橙色，橙色变为蓝色，等等。

You can enable high contrast mode in the System Menu > Accessibility > High Contrast Mode, or by pressing Ctrl+Search+H on the keyboard, followed by “Continue.”

您可以在系统菜单>辅助功能>高对比度模式下启用高对比度模式，或者在键盘上按Ctrl + Search + H，然后按“继续”。

使用屏幕放大镜增加一切的大小 (Increase the Size of Everything With a Screen Magnifier)

The screen magnifier for Chrome OS has two options to choose from: fullscreen or a docked magnifier. Fullscreen is a static magnification that increases the size of everything on the screen, while the docked version only magnifies the area around the mouse cursor. Either mode can magnify from 2X up to 20X. You can enable either option the System Menu > Accessibility.

Chrome操作系统的屏幕放大镜有两个选项可供选择：全屏或停靠放大镜。 全屏显示是静态放大，可增加屏幕上所有内容的大小，而停靠版本仅放大鼠标光标周围的区域。 两种模式均可从2倍放大到20倍。 您可以启用系统菜单>辅助功能中的任何一个。

Here’s a look at the docked magnifier at 2X zoom:

这是2倍变焦时停靠的放大镜的外观：

Warning: 20X magnification is no joke. If you do select it by accident, you can decrease the magnifier with Ctrl+Alt+brightness down button (F6) or Ctrl+Alt+scroll down with two fingers on the touchpad.

警告：20倍放大不是笑话。 如果确实选择了它，则可以使用Ctrl + Alt +亮度降低按钮(F6)或Ctrl + Alt +向下滚动两根手指在触摸板上减小放大镜。

调整其他显示设置 (Adjust Additional Display Settings)

There are additional display options available in the Accessibility menu that allow you to adjust your screen resolution—to make everything on your screen appear larger and more comfortable to see—and adjust the harsh glow of blue light on your eyes at night with a few additional display device settings.

“辅助功能”菜单中提供了其他显示选项，这些选项可让您调整屏幕分辨率-使屏幕上的所有内容看起来更大，看起来更舒适-并在夜间通过一些其他操作来调整蓝光在您眼睛上的刺眼光芒显示设备设置。

Head into the Accessibility settings by clicking into the System Menu > Accessibility > then the Settings Cog. From there, click on “Manage Accessibility Features.”

通过单击系统菜单>辅助功能>设置齿轮，进入辅助功能设置。 从那里，单击“管理辅助功能”。

Under the Display section, click on “Open display device settings.”

在“显示”部分下，单击“打开显示设备设置”。

Inside, you can set the display’s resolution, orientation, or set up a night light—to remove blue light and make the screen easier on your eyes at night.

在内部，您可以设置显示器的分辨率，方向或设置夜灯，以消除蓝光并使夜晚的屏幕更容易在您的眼睛上观看。

If the on-screen text is difficult to read or it strains your eyes, you can change the size and style of font in Chrome OS. Just head into the Accessibility settings and under the Display section, click on “Open appearance settings.”

如果屏幕上的文字难以阅读或使眼睛疲劳，则可以在Chrome操作系统中更改字体的大小和样式。 只需进入“辅助功能”设置，然后在“显示”部分下，单击“打开外观设置”即可。

It redirects you to the Appearance section in the Settings app. At the bottom of the section, choose the font size, customize the font, or increase the page zoom to make everything easier to see.

它将您重定向到“设置”应用中的“外观”部分。 在该部分的底部，选择字体大小，自定义字体或增加页面缩放比例，以使所有内容都易于查看。

键盘和文字输入 (Keyboard and Text Input)

Keyboard and text input include sticky keys— a feature that enables sequential keyboard shortcuts—an on-screen keyboard, and text dictation (speak-to-type). If you use your keyboard to navigate Chrome OS and browse the web, then you can make use of highlight features that show navigational focus on-screen.

键盘和文本输入包括粘滞键(此功能可启用顺序的键盘快捷键)，屏幕键盘和文本听写(语音输入)。 如果您使用键盘导航Chrome操作系统并浏览网络，则可以利用突出显示功能在屏幕上显示导航焦点。

对键盘快捷键使用顺序键入 (Use Sequential Typing for Keyboard Shortcuts)

The Sticky Keys feature is ideal for people who have trouble pressing more than one key at a time. It remembers each key you push, allowing you to take your finger off to press additional keys in a command. It frees up your fingers from having to press multiple keys all at the same time and instead take your time to push them in sequence with one finger. So, for example, if you want to take a screenshot, instead of pressing the Ctrl + []]] keys simultaneously, you can press them in tandem—first Ctrl, then []]].

粘滞键功能非常适合那些一次不能按下多个键的人。 它会记住您按的每个键，让您将手指移开以按下命令中的其他键。 它使您的手指不必同时按多个键，而使您腾出时间用一根手指依次按动它们。 因此，例如，如果您要截屏，而不是同时按Ctrl + []]键，则可以一前一后地按它们-先按Ctrl，再按[]]]。

When activated, a box appears in the upper left corner with the current ‘stuck’ key and a list of other keys available to press. Pressing the key a second time locks it, which lets you key in multiple commands without the need to press them again, indicated by an underline. Press the key a third time to cancel a stuck key.

激活后，左上角会出现一个框，其中包含当前的“卡住”键和其他可供按下的键的列表。 第二次按下该键将锁定它，这使您可以键入多个命令，而无需再次按下它们，并带有下划线。 第三次按该键可取消卡住的键。

放弃物理键盘以使用屏幕键盘 (Ditch the Physical Keyboard for an On-Screen Keyboard)

When enabled, a keyboard icon appears next to the notification area and clock, click it to bring up the keyboard or click inside any text field to bring up the keyboard.

启用后，键盘图标将出现在通知区域和时钟旁边，单击该图标可以调出键盘，或者在任何文本字段内部单击以调出键盘。

A few neat features that come along with the on-screen keyboard include handwritten text input, windowed mode—a feature that allows you to undock the keyboard from the bottom of the screen—and speak-to-text.

屏幕键盘随附的一些简洁功能包括手写文本输入，窗口模式(此功能使您可以从屏幕底部取消对接键盘的功能)和语音转换。

If you don’t see these options, click the arrow icon on the left-hand side of the keyboard and they should appear in the bar next to it.

如果看不到这些选项，请单击键盘左侧的箭头图标，它们应出现在旁边的栏中。

使用语音朗读将您的思想讲授到任何文本字段中 (Dictate Your Thoughts Into Any Text Field With Speak-to-Text)

If you don’t want to enable the on-screen keyboard to use speak-to-text, your Chrome OS also has a standalone accessibility feature specifically for dictation. After you enable speak-to-text from the Accessibility section in the system tray, a microphone icon appears on the shelf, next to the clock.

如果您不想让屏幕键盘使用语音朗读功能，则Chrome操作系统还具有专门用于听写的独立辅助功能。 从系统任务栏中的“辅助功能”部分启用语音转换后，麦克风图标将出现在时钟旁边的架子上。

Click the icon to turn on dictation and anything you say gets input into a text field.

单击该图标打开听写，您说的任何内容都会输入到文本字段中。

Note: Anything you say while dictation is listening is sent to Google to work correctly. If you don’t want Google having a record of everything you say, don’t use dictation.

注意：您听听听写内容时所说的任何内容都会发送到Google以使其正常工作。 如果您不希望Google记录您所说的所有内容，请不要使用听写。

使用键盘导航时突出显示对象 (Highlight Objects When Using Keyboard Navigation)

When you use a keyboard to navigate Chrome OS or to browse the internet, it can be challenging to see exactly where the focus lays, missing the small dotted line that surrounds each element. For that, enable “Highlight the object with keyboard focus when it changes” to display an orange perimeter around your intended focus. Now, any time you hit Tab to jump between links on-page, you don’t need to scan the whole page to locate the focus.

当您使用键盘导航Chrome操作系统或浏览Internet时，要准确地知道焦点的位置可能会很困难，而缺少围绕每个元素的小虚线。 为此，启用“突出显示具有键盘焦点的对象”，以在预期焦点周围显示橙色范围。 现在，只要您按Tab即可在页面上的链接之间跳转，则无需扫描整个页面即可找到焦点。

当其位置改变时突出显示文本光标 (Highlight the Text Cursor When Its Position Changes)

This feature works similarly to the one above but instead of keyboard focus. It highlights the text caret—the blinking vertical line that appears when you click in a text box—when it appears or moves position. Anytime you click or start to type in a text field, a blue aura surrounds the caret.

此功能与上面的功能相似，但没有键盘聚焦。 当它出现或移动位置时，它将突出显示文本插入符号(当您在文本框中单击时出现的垂直竖线闪烁)。 每当您单击或开始在文本字段中键入内容时，插入符号周围都会出现一个蓝色光环。

更改键盘设备设置 (Change Keyboard Device Settings)

Under the Keyboard and Text Input section in Accessibility settings, there’s a sub-menu that lets you change the behavior of pressing keys on the keyboard and functionality of the top-row keys.

在“辅助功能”设置中的“键盘和文本输入”部分下，有一个子菜单，可让您更改按键盘上的键的行为以及顶行键的功能。

Under Settings > Manage Accessibility Features, click on “Open keyboard device settings” to see a list of available features.

在设置>管理辅助功能下，单击“打开键盘设备设置”以查看可用功能列表。

Here you can change the top row of keys into Windows-style “Function Keys” and enable whether you want keys to repeat if you continue to hold it down. You can also set the delay and repeat rate between the output of each character on screen.

在这里，您可以将按键的第一行更改为Windows样式的“功能键”，并启用是否要在您继续按住时重复按键。 您还可以设置屏幕上每个字符的输出之间的延迟和重复率。

鼠标和触控板 (Mouse and Touchpad)

Mouse and touchpad accessibility focus on visibility of the cursor and how you interact with a mouse/touchpad. These features help you make the pointer easier to see, reduce the need to click your mouse physically, and highlight the cursor when it moves.

鼠标和触摸板的可访问性着重于光标的可见性以及与鼠标/触摸板的交互方式。 这些功能可帮助您使指针更易于查看，减少物理上单击鼠标的需要以及在光标移动时突出显示光标。

通过自动点击减少物理鼠标的按下次数 (Reduce Physical Mouse Presses With Automatic Clicks)

This feature eliminates the need actually to click the mouse/touchpad. Whenever you stop the cursor, a timer starts and will initiate the click for you if it remains unmoved. You can set the timer to different intervals that range from “Extremely Short (0.6s)” to “Very Long (4s).”

此功能消除了实际单击鼠标/触摸板的需要。 每当您停止光标时，计时器都会启动，并且如果单击保持不变，它将为您启动单击。 您可以将计时器设置为不同的间隔，范围从“极短(0.6s)”到“极长(4s)”。

增大鼠标光标大小即可轻松找到鼠标指针 (Easily Find Your Mouse Pointer With Increased Mouse Cursor Size)

Chrome OS’s default mouse cursor is by far one of the most challenging things to locate on-screen, even for someone with perfect 20/20 vision. Luckily, with this accessibility feature, you can change the size of the pointer up to an almost comical foam-finger size.

到目前为止，Chrome OS的默认鼠标光标是在屏幕上定位最具挑战性的内容之一，即使对于视力达到20/20的人来说也是如此。 幸运的是，通过此辅助功能，您可以将指针的大小更改为几乎可笑的泡沫手指大小。

()

当其位置改变时突出显示鼠标光标 (Highlight the Mouse Cursor When Its Position Changes)

How many times have you frantically wiggled the mouse, squinting at the screen in a desperate attempt to find your cursor? We’re all guilty of it, and with this feature, all you have to do is move the pointer, and a red circle surrounds it, which makes it way easier to spot on the screen.

您疯狂地摇动了鼠标几次，在屏幕上斜视着，不顾一切地试图找到光标？ 我们都对此感到内，使用此功能，您要做的就是移动指针，并在其周围环绕一个红色圆圈，这使在屏幕上更容易发现。

其他鼠标和触摸板设备设置 (Additional Mouse and Touchpad Device Settings)

There are a few other mouse and touchpad settings you can access from a sub-menu that lets you customize them even further.

您还可以从子菜单访问其他一些鼠标和触摸板设置，使您可以进一步自定义它们。

From Settings > Manage Accessibility Features and under the Mouse and Touchpad section, click “Open mouse and touchpad device settings” to open the settings.

在“设置”>“管理辅助功能”中，在“鼠标和触摸板”部分下，单击“打开鼠标和触摸板设备设置”以打开设置。

Inside you can find swap mouse button, reverse scroll direction, change mouse speed, for the mouse. Then for the touchpad, you can change touchpad speed, enable tap-to-click or tap dragging—double-tap, then drag windows around—and scrolling orientation.

在内部，您可以找到交换鼠标按钮，反向滚动方向，更改鼠标速度。 然后，对于触摸板，您可以更改触摸板速度，启用点击单击或点击拖动(两次点击，然后在周围拖动窗口)以及滚动方向。

音讯 (Audio)

Chrome OS offers a couple of audio related accessibility features to round things out. You can enable mono mode to have all speakers play the same audio or have Chrome OS play a sound when it starts up.

Chrome操作系统提供了一些与音频相关的辅助功能，以使操作更为完善。 您可以启用单声道模式，让所有扬声器在启动时播放相同的音频或让Chrome OS播放声音。

通过所有扬声器播放相同的音频 (Play the Same Audio Through All Speakers)

A majority of devices use “Stereo” mode to play audio from your speakers/headphones with more than one channel (left and right). If you’re hard of hearing in one ear or only listen to audio using one earbud/speaker, you can easily switch your Chromebook to “mono” mode, so the same audio comes out of all speakers.

大多数设备使用“立体声”模式播放来自多个声道(左和右)的扬声器/耳机的音频。 如果您一只耳朵听不到声音，或者仅使用一只耳塞/扬声器收听音频，则可以轻松地将Chromebook切换为“单声道”模式，这样所有扬声器都可以听到相同的音频。

Chrome操作系统启动时播放声音 (Play a Sound When Chrome OS Starts Up)

Just as the title suggests. When you start up Chrome OS, a sound plays to signal it’s ready for you to sign in. You can only enable this feature through Settings > Accessibility > Manage Accessibility Features.

正如标题所示。 启动Chrome操作系统时，系统会发出声音提示您可以登录。只能通过“设置”>“辅助功能”>“管理辅助功能”来启用此功能。

Chrome OS does a great job to include everyone, regardless of their ability to use a standard computer or not. With this comprehensive list of accessibility features, it’s easy to add any number to your laptop that tailors it to your unique needs.

无论是否使用标准计算机，Chrome操作系统都能很好地使所有人参与进来。 借助此全面的辅助功能列表，您可以轻松地在笔记本电脑上添加任何数量的数字，以使其满足您的独特需求。
