Why does dictation type my command instead of doing it?

Dictation types your command when the software is in a mode that types every word it hears. A phrase such as "delete that" is also ordinary English, so the mode and settings decide whether it is acted on or typed. On a Mac, the usual fix is a mode change: Command mode in Apple's Voice Control. On Windows, the settings to check are the wait time before a command runs and the pauses you leave around it. This is a mode and settings problem, not a fault in the phrase.

The mode decides whether a phrase is acted on or typed

On a Mac, Apple's Voice Control has two working modes. Dictation mode is on by default, and in it "Any words you say that aren’t Voice Control commands are entered as text" ¹. So a command you say in Dictation mode can be entered as text when Voice Control does not treat it as a command. Apple's page states the default plainly: "Dictation mode is on by default" ².

That is the default working as designed. In Dictation mode, any words that are not commands are typed, so a phrase that Voice Control does not act on ends up in the text.

Command mode acts on commands and ignores everything else

Command mode is the switch for this problem. Apple says that "Voice Control responds only to commands. Words and characters that aren’t commands are ignored and aren’t entered as text." ³ Apple advises it for exactly this case: "To avoid mistakenly entering a Voice Control command as text, have Voice Control respond only to commands (with Command mode)" ⁴.

To switch, say "Command mode" in Voice Control, and say "Dictation mode" to return to dictating words ( Apple: Voice Control commands). Command mode is helpful when you need to say a series of commands and do not want them entered in the text field. It also means ordinary words are ignored, so you should switch back before you dictate a sentence.

Windows has two settings that change how commands behave

Windows voice typing has a wait time setting, which controls how long voice typing waits before it carries out a voice command. Microsoft says the setting gives more accurate recognition whether you speak slowly or quickly ⁵. If a command fires before you finish, or waits too long, change the wait time. Microsoft's settings page also lists an Automatic punctuation option, which inserts punctuation based on what you say ( Microsoft: Use voice typing).

Windows Voice Access works in the other direction. It has a deliberate prefix for typing a command word on purpose: "Type" or "Dictate" before a voice access command inserts that command as text in a text box ⁶. If you need a command word inside your text, use that prefix. If you need the command carried out, say it without the prefix.

Pauses separate a command from the words around it

A command runs more reliably when it stands alone. Apple advises that when you say commands in quick succession, you "pause about half a second between commands" ⁷. That advice is for commands in a row, but the same idea helps with a command in the middle of a sentence: pause briefly before and after it. This is advice, not a measured effect.

Commands are easy to forget, so keep the list short

Speech commands are fast to use, but they are easy to forget. A 1992 study found that participants made significantly more memorization errors when they used speech rather than the mouse to activate commands ⁸. If a command keeps being typed, you may also be saying a phrase you half remember. Learn three or four commands you use every day, and check the guide to dictation commands for the phrases each tool uses.

It depends on what you want to happen

• You want the command carried out. Switch to Command mode on a Mac, check the wait time on Windows, and pause before and after the phrase.
• You want the words typed. On Windows, use the "Type" prefix in Voice Access. On a Mac, stay in Dictation mode and expect the phrase to be typed.
• Nothing is typed at all. That is a different problem, covered by the dictation not working guide, which checks the microphone and the app.

What to do

1. Check the mode first. On a Mac, say "Command mode" for a series of commands, and "Dictation mode" before you dictate a sentence.
2. Check the wait time. On Windows, open voice typing settings and adjust the wait time if commands run too early or too late.
3. Pause before and after the command. A short break makes the phrase stand apart from the words around it.
4. Use the "Type" prefix only when you want the words typed. In Voice Access, that prefix is the way to type a command word on purpose.
5. Keep the list short. Learn the few phrases you use every day, then look up the rest.

For the editing phrases themselves, see the question on deleting a word by voice and the question on correcting a misheard word. The question on dictation and voice control explains which mode is which. The spoken punctuation term defines the punctuation phrases, which can also be typed by mistake.
