How to dictate on a Mac, and what to do when it stops working

Every Mac has dictation built in. This page sets it up, fixes the four things that usually break it, and says plainly where a dedicated app earns its place.

How do you turn on dictation on a Mac?

Dictation ships with macOS and costs nothing. Open System Settings → Keyboard → Dictation and switch it on. In the same pane you choose the shortcut that starts it — the microphone key on recent keyboards, or Control pressed twice — and add the languages you intend to speak. Once it is on, the shortcut works in any text field: Mail, Notes, a browser, a terminal.

That is the whole setup, and for a short reply it is genuinely all you need. What follows is what to do when it does not behave, and what a dedicated app adds once you are dictating all day rather than a sentence at a time.

Why is dictation not working on your Mac?

Four things explain most of it, and all four are free to check before you install anything.

• The shortcut is set to Off. In System Settings → Keyboard → Dictation the shortcut has its own menu, and Off is a valid setting. Pressing the key then does nothing at all, which reads exactly like a broken feature.
• The language was never added. Dictation only listens for languages in its own list. If you are speaking one that is not there, it will either produce nothing or transcribe it as though it were English.
• The Mac is listening to the wrong input. Check System Settings → Sound → Input. An idle Bluetooth headset that is still connected will be selected ahead of the built-in microphone, and it is the single most common cause. This one catches any dictation app, ours included.
• Microphone permission was declined. System Settings → Privacy & Security → Microphone lists every app that has asked. An app denied here fails silently rather than prompting again.

If all four are right and it still misbehaves, the problem is usually not the setup: it is that built-in dictation is designed for short bursts, and gets less reliable the longer you talk.

What is the dictation shortcut on a Mac?

Whatever you set it to. macOS offers the microphone key or a double-press of Control, and lets you pick a custom combination. Lesskeys uses its own global shortcut, ⌥ ., so the two never collide — and it is changeable too, for anyone whose muscle memory already belongs to something else.

Why does local dictation matter once you dictate all day?

A sentence into a search box is not the same job as dictating a clinical note, a client file or an unpublished draft. At that point two things start to matter: whether the audio is leaving the machine, and whether there is a meter running.

Lesskeys does the whole thing on your own Mac. A speech model runs on the GPU, the text lands on your clipboard, and one ⌘V puts it where the cursor already was. There is no account, no per-minute charge, and no network call once the model is in place — it works with the Wi-Fi off.

What does a dedicated app add?

• Recordings, not just live speech. Built-in dictation types what you are saying now. Lesskeys also transcribes audio and video files you already have.
• Who said what. Speaker labels are worked out on the machine, so an interview comes back readable rather than as one block.
• Your choice of model and language. 99 languages, detected automatically, with no time limit on how long you speak.
• One shortcut everywhere. The same key in Mail, Word, Slack, Xcode or a browser, with the result on the clipboard rather than typed into whatever had focus.

If all you want is to dictate a short message, the dictation already on your Mac is free and fine, and we would rather say so. Compare the Mac dictation apps before deciding anything.
