谢谢！受你启发，我的是Mac电脑，也找到了speak text 的功能，真方便啊，对语言学习很有帮助：
Have your Mac speak text that’s on the screen
If you have trouble reading text on your screen, you can have your Mac speak the text whenever you press a key or set of keys.
On your Mac, choose Apple menu > System Preferences, click Accessibility, then click Speech.
Select the “Speak selected text when the key is pressed” checkbox.
By default, speaking is enabled when you press Option-Esc. To choose a different key, click Change Key, press one or more modifier keys (Command, Shift, Option, or Control) together with another key, then click OK.
To have your Mac start speaking, press the specified key. To stop the speaking, press the key again.
If text is selected when you press the key, the selected text is spoken. Otherwise, available text items in the current window are spoken; for example, if Mail is the current window, an email message is read.
Note: If no text items are available, you hear a beep.
如果文章是英文的，你可以选择讲美式英语的播音员来读，也可以选择讲英式英语的播音员来读。你还可以选择男士或女士来读。语言不限于英语，可以是法语，俄语，德语，西班牙语，日语，汉语，等等。
如果是汉语，你可以选择讲普通话的男士或女士来读。如果你选择讲广东话的人来读，那么你就可以很容易学会广东话了。
而且，你还可以自由调节播音速度。
现在，你就可以开始了：
第一步：用Windows 10里的edge打开任何你希望读的文章网页（例如此网页）；
第二步：按鼠标右键，然后在打开的菜单中选择"Read aloud"。
Windows 会自动根据网页中文章所使用的文种来选择合适的播音员。
如果你想选择不同的播音员或者播音速度，你只要点击网页右上角的“Voice options”，就可选择你喜欢的播音员和播音速度了。
