Dictate Slack Messages — Faster Replies, Better Threads
SuperSpeech lets you dictate Slack messages at speaking speed. Replies, status updates, long thread explanations — all with a hotkey.
Slack is a writing-heavy tool. Knowledge workers spend hours per week typing messages that take 5x longer to write than to speak. SuperSpeech dictates into Slack — in the desktop app, web app, or mobile-on-Mac — at speaking speed. Replies become shorter, threads become more substantive, and async communication stops being a bottleneck.
How it works in Slack
Position your cursor in any Slack message field (channel, DM, thread reply, or edit mode). Press your SuperSpeech hotkey. Speak your message. Press again to stop. Text appears, ready to send or edit. No Slack plugin, no integration setup.
- Works in Slack desktop app (Mac + Windows) and Slack web
- Dictate into channels, DMs, threads, and edit mode
- Custom dictionary for team jargon, project codenames, people names
- Grammar correction cleans filler words automatically
- Push-to-talk for quick replies, toggle for longer messages
Three Slack workflows
Common patterns SuperSpeech users adopt in Slack:
- Long thread replies: dictate your full context instead of fragments
- Async status updates: speak the weekly update into #proj-updates
- Voice memos: capture a 2-minute thought as text rather than a voice clip
Custom dictionary for Slack
Teams have vocabulary: project codenames ("Project Atlas"), internal acronyms ("RFC"), people names ("Özge"), and repeating commands ("/standup"). Add them to the SuperSpeech custom dictionary once, and every future dictation renders them correctly.
Privacy for sensitive channels
For channels discussing HR, legal, customers, or strategy, audio never leaving the device matters. Unlike Slack's own voice clips (which are cloud-stored) or meeting bot transcription, SuperSpeech text is dictated locally and only the final characters reach Slack.
Frequently Asked Questions
Does it work in Slack Huddles?
For text replies inside a Huddle, yes. For transcribing the Huddle conversation, that is meeting transcription — use a meeting tool for that.
Can I dictate thread replies?
Yes. Click into the thread reply field and dictate as normal.
Does it work with Slack on mobile?
Only on iPad via Universal Control. For iPhone/Android, use native dictation.
What about Slack web vs desktop?
Both work identically. Slack web in any browser accepts SuperSpeech dictation the same way.
Can I add team members' names to dictionary?
Yes. Add each name once, with common variants. SuperSpeech will render names correctly in every message.
