Voice to text in Claude on Mac

Yes, you can talk to Claude instead of typing to it, and on a Mac you have two ways to do it. Claude ships its own dictation button, and Sayburst puts dictation on a key you hold from anywhere: click into Claude's message box, hold fn, explain what you need, let go, and the cleaned-up prompt is waiting to send.

That matters more in Claude than almost anywhere else. Claude does its best work with context, and context is exactly what you skip when you're typing. Spoken, the background, the constraints and the "oh, and one more thing" come out in thirty seconds.

#What Claude has built in

Claude's help pages describe three voice features, checked at the end of October 2026:

• Dictation. A microphone in the message box on claude.ai, the desktop app and mobile. You speak, the words appear in the box, and you edit before sending.
• Quick Entry dictation on Mac. Press Caps Lock to dictate into the Quick Entry window. It's off by default because it takes over Caps Lock, and it needs macOS 14 or later plus Speech Recognition permission.
• Voice mode. A spoken conversation in beta where Claude talks back. Text transcripts are saved in your chat history.

If you only talk to Claude now and then, the built-in microphone is enough. Sayburst is for when you dictate to Claude all day, and want the same key, the same cleanup and the same vocabulary in Claude, your editor, your email and everywhere else.

#How to set it up

1. Install Sayburst and allow two permissions. Microphone so it can hear you, Accessibility so it can type into Claude. The speech model downloads once and runs on your Mac from then on.
2. Pick how prompts should land. In Sayburst's modes, set the Claude app (and your browser, if you use claude.ai) to Clean, so prompts arrive as tidy paragraphs instead of a formatted email. Decide on auto-send: with it on, Sayburst presses Return after inserting, and Claude sends the message straight away. Leave it off if you like to read a prompt before it goes.
3. Click the message box, hold fn, talk, let go. The overlay shows your words as you speak. Release the key and the prompt drops into Claude. For a long brief, tap fn once to go hands-free and tap again to finish.

#Prompts, said out loud

A data question, with the false start people make when thinking aloud:

"Okay so I've attached the, the Q3 churn export. I want you to find which plan loses the most people in the first thirty days, actually no, make it the first sixty days, and give me three guesses why, ranked by how much of the data backs each one."

What lands in Claude, with Sayburst Writer on:

I've attached the Q3 churn export. I want you to find which plan loses the most people in the first 60 days, and give me three guesses why, ranked by how much of the data backs each one.

The repeated "the" is gone, the thirty-day version you abandoned is gone, and the number is written as a number.

Feedback on a draft Claude just wrote, which is where most of the back-and-forth happens:

"That's close. Um, keep the second paragraph, cut the bit about pricing, and the tone is too, too formal for a Slack update."

That's close. Keep the second paragraph, cut the bit about pricing, and the tone is too formal for a Slack update.

One detail worth knowing: Sayburst Writer treats your speech as text to clean, never as instructions. If you say "summarize this thread in five bullets", Sayburst types that sentence and Claude does the summarizing. Your prompt reaches Claude as you meant it.

#Claude's dictation vs Sayburst

#Where your words go

Keep the steps apart:

• Recognition (your voice becoming text) happens on your Mac. Sayburst never uploads your audio.
• Cleanup (punctuation, fillers, repeats) runs on your Mac too, and so does Sayburst Writer, the optional AI model that resolves self-corrections.
• An optional cloud writer. If you'd rather a Claude model did the cleanup, you can add your own Anthropic API key. Only the transcribed text goes to Anthropic for that step, and Sayburst shows exactly what will be sent before you switch it on.
• Claude itself receives the prompt once you send it, like anything you type, and keeps the conversation under your Claude account's settings.

So dictating with Sayburst keeps your voice off the network. What you then send to Claude is a separate decision, the same one you make when you type.

#Tips for talking to Claude

• Teach it your project's words. Add product names, client names and code identifiers to Sayburst's vocabulary. A prompt about "the Halverson renewal" should say Halverson, not Halverston. Here's how vocabulary works.
• Transcribe the recording first. Got a voice memo or a call recording you want Claude to work through? Drop it on Sayburst's History window, which transcribes it on your Mac, and paste the text into Claude with your question.
• Rewrite your own draft before sending. Dictated a messy prompt? Select it in the message box, hold the rewrite shortcut and say "make this shorter". The selection is replaced.
• Don't lose a long brief. If Claude's window loses focus mid-dictation, Sayburst keeps the text and offers it back. Press ⌃⌥⌘V to paste your last dictation wherever you are. More on how that works.
• Same key in the docs you'll paste from. The shortcut works in Google Docs, Mail and Notes, so the material you hand Claude can be dictated too.

#Limits worth knowing

Sayburst inserts the prompt when you finish speaking, not word by word into the box while you talk; the overlay shows the words live. It writes and never talks back, so for a spoken conversation use Claude's voice mode. There's no official Claude integration and none is needed: Sayburst types into Claude the way your keyboard does. It needs an Apple silicon Mac on macOS 14 or later, and it doesn't run on Windows, iPhone or Android, where Claude's own microphone is the way to go.

Questions people ask

Does Claude have speech to text?

Yes. Claude has a dictation microphone on the web, desktop and mobile apps, and the Mac app's Quick Entry can dictate with Caps Lock once you turn that on. Sayburst adds a hold-to-talk key that works in Claude and every other app on your Mac.

Can Claude transcribe audio files?

Claude's upload help lists documents and images, not audio. To get a recording into Claude, drop the file on Sayburst's History window, which transcribes it on your Mac, then paste the text into your chat.

Does Claude have a voice mode that talks back?

Yes. Claude's voice mode is a spoken back-and-forth, in beta, on mobile, desktop and the web, and its transcripts are saved in your chat history. Sayburst only writes: it turns your speech into text and never speaks a reply.

Can Sayburst use my Anthropic API key?

Yes, as an optional writer. With your own Anthropic key, Sayburst sends only the transcribed text for cleanup, never audio, and shows exactly what will be sent before you turn it on.
