Read selected text aloud: the shortcut for Mac and Windows

The pattern: select, trigger, listen

Almost every "read this aloud" workflow boils down to three steps: select some text with your mouse or trackpad, trigger a read-aloud action, and listen. The differences between tools are really about how painless step two is — whether it's an instant, memorized keystroke or a multi-click detour through a settings menu or a different app entirely.

Step by step on Mac: Option+Esc

macOS has this built in, but it's off until you switch it on. Here's the actual setup:

1. Open System Settings → Accessibility → Spoken Content.
2. Toggle on Speak Selection.
3. Select any text anywhere on your Mac and press Option+Esc (the default shortcut — changeable in the same panel).

Once set up, it works across the whole system using one of macOS's built-in voices. The friction is entirely in that first-time setup — most Mac owners never open Accessibility settings and don't know this feature exists — and the voice itself is functional but sounds synthetic over anything longer than a sentence or two.

Step by step on Windows: no single native shortcut

Windows doesn't have one unified answer here. There are three separate paths, each with its own trigger:

• Narrator — toggled with Windows+Ctrl+Enter, but it's a full screen reader for accessibility navigation, not a lightweight "read my selection" tool, and it takes over your whole interface narration rather than just speaking the text you selected.
• Edge's Read Aloud — a toolbar button inside Microsoft Edge that reads the current page, but it only works inside Edge.
• Word's Read Aloud — a Review-tab button that reads the open document, but only inside Word.

There's no built-in shortcut that reads a text selection aloud regardless of which app it's in — which is the exact gap a lot of people searching for "read selected text shortcut" are trying to fill.

Shmia's shortcut: one combo, every app

Shmia installs the missing piece: a single global shortcut that works the same way in every app on both operating systems, no per-app setup required.

Select text in a browser, a PDF, an email client, a Word document, a code editor, a chat app — press the shortcut, and it starts speaking in about a second. Under the hood, it streams the first sentences of your selection immediately while it keeps generating the rest, so it holds up on long selections just as well as short ones. A small floating player appears with a live timeline, play/pause, and a 0.75x–2x speed control that changes instantly without altering pitch, and it never steals keyboard focus away from what you're doing.

If remembering a shortcut isn't your style, you don't have to: selecting text also brings up a small play bubble right next to the selection, and clicking it does the same thing as pressing the shortcut. It's the same core mechanic — select, trigger, listen — with two ways to do step two, whichever fits how you work.

On Mac, the first launch requires right-clicking the app and choosing Open to get past Gatekeeper's warning for apps outside the App Store. On Windows, SmartScreen may show a similar warning since Shmia is a young app — click More info → Run anyway to proceed.

Which should you use?

If you only need this occasionally and don't mind a synthetic voice, macOS's built-in Speak Selection is free and already there once you dig it out of Accessibility settings. On Windows, there's no equivalent built-in shortcut at all unless your reading happens to live entirely in Edge or Word. If you want one shortcut that works everywhere, on either OS, with better-sounding voices and a genuinely unlimited free tier, that's exactly the gap Shmia fills.
