How to dictate in Slack on a Mac
Yes, you can dictate in Slack on a Mac. Apple Dictation steps, how to stop Return sending half a message, Slack's audio clips, and dictation that adds lines.
To voice type in WhatsApp on a Mac, click into the message box, start Apple Dictation with the Microphone key, your Dictation shortcut or Edit > Start Dictation, and talk. Return sends in WhatsApp, so add lines with Shift-Return, or use dictation like Koi that types a line break as Shift-Return and leaves the full stop off.

Built in
WhatsApp's message box on a Mac is a text field, so the Mac's own Dictation types into it, in the WhatsApp app and in WhatsApp Web. The steps follow Apple's Dictation guide for macOS 27, checked October 21, 2026.
Apple Dictation adds commas and full stops by itself in supported languages, so a quick reply often ends with a full stop people don't use in chat. You can turn Auto-punctuation off in Keyboard settings, but then it's off everywhere. Say an emoji by name, like “heart emoji”, and Dictation types it. More in our guide on how to dictate on a Mac.
Return sends
In WhatsApp on a Mac, Return sends the message and Shift-Return adds a line. With dictation, that's the thing to watch: a line break that arrives as a plain Return sends whatever you've said so far. Try Apple's spoken “new line” in a chat with yourself first, or keep each message to one paragraph and add breaks with Shift-Return by hand.
WhatsApp's own
WhatsApp's own voice feature is the voice message: you record your voice and send the recording, not text. From a computer, WhatsApp's help says:
The steps are from WhatsApp's page on previewing a voice message. For messages you receive, WhatsApp announced voice message transcripts in November 2024, made on your device, under Settings, Chats. Its steps are for phones, and we couldn't confirm the feature in the Mac app.
A voice message is right when your voice is the point. When people would rather read, skim or search your reply, dictation gets you typed text.
Koi
We make Koi, so weigh this part with that in mind. Koi's dictation handles the things a chat box needs:
The speech model runs on your Mac, so what you dictate into a chat isn't sent anywhere to become text. Typing in English from another language is covered in speaking any language and typing English.
