Lawyers were dictating long before anyone called it AI. The microcassette, the dictation pool, the assistant who knew your phrasing: for decades that was how letters and briefs got written. Today most lawyers type their own work, and many miss the old way, because the best version of an argument often comes out loud.
Dictation software for lawyers brings that back without the tape. But legal work adds two questions most dictation buyers never ask: does the tool know legal language, and where do my client's words go? This guide takes both seriously. We make LumeVoice. It's a general-purpose app with no legal certification, and for some legal work Dragon Legal or a local tool is the better pick. We'll say where.
What lawyers actually dictate#
- Client emails and letters. Status updates, advice summaries, engagement letters, cover letters.
- Memos. Research memos to a partner, file memos after a call, notes on strategy.
- First drafts. The argument section of a brief, a statement of facts, a demand letter. Not the final version; the version you can edit.
- Attendance notes. What happened at the hearing, in the meeting, on the phone, written while it's fresh.
- Comments on drafts. Marking up a junior's work or opposing counsel's redline.
- Internal messages. Teams or Slack threads with your team, instructions to staff.
Notice what's missing: formal documents generated from templates, and anything where exact wording is the whole point. Dictation helps with thinking-heavy writing. Clause-level drafting still happens at the keyboard.
What to look for#
Legal vocabulary. "Res judicata", "estoppel", your client's company name, the judge's name. A tool that can't learn these creates proofreading work.
Cleanup or verbatim. Some lawyers want every word exactly as said. Most want readable prose. AI dictation removes filler and applies your self-corrections; verbatim tools don't. Know which you want before you choose.
Where it runs. Dragon Legal is Windows only. If you work on a Mac or want to dictate from your phone between court appearances, that matters.
Where the audio goes. Installed software that processes on your computer, a cloud service, or a cloud service with enterprise contracts. Your firm's IT and ethics policies may already have decided this for you.
The options, fairly compared#
Dragon Legal. The specialist. Nuance says its legal vocabulary was trained on more than 400 million words of legal documents, and it formats legal citations automatically, inserts standard clauses by voice, and supports word lists you can create, import and share across a firm. It also controls Windows by voice, with custom commands and macros, which LumeVoice can't do at all. It runs on Windows 11 and 10; there's been no Mac version since 2018, and the Dragon Anywhere phone app stopped selling on July 1, 2026. Nuance prices Dragon Legal by quote, as of October 2026. If your firm already uses it, there's a good chance it's still the right tool for formal drafting. See LumeVoice vs Dragon and Dragon pricing.
LumeVoice. AI dictation for Mac, Windows, iPhone and Android on one plan. Hold fn on a Mac or Ctrl + Win on Windows in any app, talk and let go: filler words go, self-corrections are applied, punctuation and paragraphs are added, and spoken lists become numbered lists. Add case names and legal terms to the custom dictionary on desktop. Snippets type text you repeat, like your standard closing paragraph. The desktop apps also transcribe audio files. It's cloud-based, needs a connection, has no legal vocabulary out of the box, no citation formatting, no voice commands and no team plan.
Wispr Flow. AI dictation on the same four platforms, also cloud-based. Pro is $15 a month or $144 a year; its Growth plan, at $18 per user per month billed annually, adds single sign-on, admin controls and org-wide HIPAA enforcement with a signed BAA, as of October 2026 (pricing details). If your firm wants one centrally managed cloud tool with a contract behind it, that's a real advantage.
Superwhisper. Can run fully on your Mac with local models, with no internet connection, and also runs on Windows, iPhone and Android. For lawyers whose clients or firms forbid sending audio to any cloud service, local processing is the strongest privacy position available (pricing). Expect more setup, and stick to the local models for client work.
Microsoft 365 Dictate and Apple Dictation. Dictate is built into Word and Outlook for firms on Microsoft 365, so there's nothing new for IT to approve. Apple Dictation is free on Mac and iPhone. Neither cleans up filler words or learns your legal vocabulary, but both are a sensible way to try the habit.
A lawyer's day, by voice#
These examples are illustrative. They show what the cleanup does, not a real matter or a measured result. The names are invented.
After the client call: the file memo#
Write the attendance note before the next call starts. Open the matter's document in Microsoft Word and talk.
You say (illustrative): "File note, call with Dana Reyes, uh, 20 minutes. She confirmed the supplier stopped deliveries on March 3rd, actually March 4th. Um, she has the emails and will send them by Friday. She wants to know whether we can, you know, recover the cost of the replacement supplier. Next steps, one, review the supply agreement termination clause, two, send her a list of documents we need."
What lands: File note: call with Dana Reyes, 20 minutes.
She confirmed the supplier stopped deliveries on March 4th. She has the emails and will send them by Friday. She wants to know whether we can recover the cost of the replacement supplier.
Next steps:
- Review the supply agreement termination clause.
- Send her a list of documents we need.
The facts in the note are only as good as what you said. Read it back before it goes in the file.
The status email#
Clients want to hear from you more often than most lawyers write. Dictated status updates in Outlook take a minute: what happened, what's next, what you need from them. Use a snippet for your sign-off and any standard confidentiality footer your firm uses.
Drafting the argument#
For the argument section of a brief or a research memo, use hands-free mode: double-press the shortcut and argue it out loud, as you would to a partner across the desk. Then edit. Dictation gets the reasoning onto the page; the citations, the defined terms and the precise language come in the editing pass, from your research tool and your precedents.
You say (illustrative): "The termination was not, um, valid because the notice period in clause 14 is 30 days, and the supplier gave, uh, 11. Even if, sorry, even if the court reads clause 14 as permissive, the supplier still failed to cure within the period in clause 15."
What lands: The termination was not valid because the notice period in clause 14 is 30 days, and the supplier gave 11. Even if the court reads clause 14 as permissive, the supplier still failed to cure within the period in clause 15.
Comments on a junior's draft#
Reviewing in Word, click into a comment and say what you'd say in person. Spoken feedback tends to explain the why, which helps juniors more than a terse "rework" in the margin.
Confidentiality and privilege: your firm's call#
Before you dictate anything about a client into any tool, check your firm's technology policy, your client's instructions (outside counsel guidelines often cover this) and your professional conduct rules on confidentiality and technology. We can't tell you whether a given tool is acceptable for privileged material, and you should be wary of any vendor that claims it can.
Here's what's true of each tool's data flow, as far as their own pages say:
- Dragon Legal is installed on your Windows PC. Nuance's release notes list an internet connection for activation, not for dictation itself. Its Anywhere editions are cloud-hosted.
- Superwhisper's local models and MacWhisper process audio on your Mac. Nothing is sent anywhere.
- LumeVoice and Wispr Flow process audio in the cloud.
LumeVoice sends your audio for processing and doesn't store it afterwards. What you say is never used to train models, and your dictation history stays on your device, not our servers. It needs an internet connection and holds no legal certification or compliance certification of any kind, and it doesn't offer firm-level contracts or admin controls. A sensible split is to use it for work with no client confidences in it (internal emails, marketing, bar association work) and a local tool or Dragon Legal for client matters. Our guide to private dictation for legal and medical work goes deeper on what to check.
Talk through the memo, then edit it
LumeVoice turns what you say into clean text in Word, Outlook or any other app on Mac and Windows, with iPhone and Android on the same plan. Check your firm's policy first, then try it with 3,000 free words, no card required.
Two practical tips#
Build your dictionary per matter. At the start of a matter, add the party names, the court, the key defined terms and any unusual place names to LumeVoice's custom dictionary on desktop. Five minutes up front saves a lot of correcting later. Dragon Legal users can do the same with shared word lists.
Keep dictation and drafting separate. Dictate into a scratch document, edit there, then move the clean text into the template. Templates with locked fields, numbering and cross-references are easier to fill than to dictate into.
The short version#
- Windows firm, heavy formal drafting, need voice commands or citation formatting: Dragon Legal.
- Client or firm forbids cloud processing: Superwhisper's local models, or MacWhisper for recordings.
- Firm wants one managed cloud tool with admin controls: Wispr Flow's Growth plan.
- On Microsoft 365 and just want to try it: Word's Dictate.
- You want clean prose in every app on Mac, Windows and your phone, and your firm allows a cloud tool: LumeVoice.
