Dictate Into Slack on Mac: Type Messages by Voice

Slack's microphone button records an audio clip of up to five minutes, with a transcript you can generate after sharing (Slack help, checked October 21, 2026). If you want a typed message instead, Sorimac turns speech into text at the cursor in the Slack app, on the Mac. It costs $9.99 once.

How do you set it up?

Install and allow access. Download Sorimac and allow Microphone and Accessibility so it can paste into Slack.
Set Auto Return for chat. Auto Return is on by default and presses Return a second after your words land, which sends a Slack message. Keep it if you like hands-free replies; set a longer delay or Off if you want to reread first.
Click the message box and speak. Pick the channel or thread, click the message field and say your reply.

What to watch for in Slack

Return sends in Slack

Because Return sends a message in Slack, Auto Return means each finished sentence goes out. Sorimac waits until it is no longer transcribing and nothing new has been typed, but a half-finished thought can still be sent. A two or three second delay gives you time to keep talking.

Keep it out of the wrong chat

Add apps you never want dictation in to Excluded Apps. While one of them is in front, Sorimac stops typing and the menu bar shows that dictation is paused.

Push-to-Talk in shared rooms

In an office or on a call, Always On may pick up what you say to others. Push-to-Talk types only while you hold the key you chose.

Your clipboard

Sorimac pastes via the clipboard and puts your previous text back about a second later. Only text is restored, and clipboard managers will usually record each dictation.

Slack's own voice features vs Sorimac

Slack's help center describes audio and video clips up to five minutes long. Clips are not transcribed automatically; you can select Generate transcript after sharing. Huddles can have AI notes and a transcript in a canvas. We did not find a Slack feature that types speech into the message field on desktop.

Clips suit a longer update people can listen to. Sorimac suits replies people will read and search, written as text before anyone sees them.

FAQ

Does Slack have dictation on desktop?

Slack's help pages describe voice clips with optional transcripts, not dictation into the message box. On a Mac, use macOS Dictation or an app like Sorimac for typed messages.

Will Sorimac send my Slack message automatically?

Only if Auto Return is on, which is the default with a one second delay. Set it to Off or a longer delay in settings.

Is what I say sent to anyone?

Speech recognition runs on the Mac. Only the text you dictate goes into Slack, like typing.
