Voice to text for consultants: field notes without NDA risk

For a consultant, the best use of voice to text is the ten minutes after a client session: speak what you heard while it is fresh, in a fixed structure, then tidy it into a note. Emails and first drafts of proposal sections work well too. The constraint is the client's confidentiality terms, not the software. Before you dictate anything covered by an NDA, know where the audio is processed, where the text is stored, and whether any AI step sends it to a third party, and do not dictate aloud where the wrong people can hear.

What does client confidentiality mean for dictation?

Your NDA or engagement letter is the document that counts. Read its confidentiality clause for three things: who may receive client information, whether subcontractors or service providers count as recipients, and whether information may be stored outside your or the client's systems.

The profession's own code points the same way. The IMC USA Code of Ethics, which IMC USA members and Certified Management Consultants pledge to follow, says in 5.0: "I will treat appropriately all confidential client information that is not public knowledge, take reasonable steps to prevent it from access by unauthorized people". Code 12.0 adds respect for other firms' "proprietary information or methodologies".

Applied to dictation, "reasonable steps" means tracing every place your words go:

For Apple's built-in Dictation, Apple's Mac User Guide says the Dictation section of Keyboard settings tells you "whether your voice inputs and transcripts for general text Dictation (for example, composing messages and notes, but not dictating in a search box) are processed on your device and not sent to Siri servers." Check that line on your Mac. For any other tool, read its privacy page and settings. Where does my dictation go? walks through the questions.

A routine for turning a brain-dump into a structured note

Spoken notes go wrong when they are a stream of consciousness. Give yourself the headings first, then talk under each one.

1. Type the header: client code name, date, session, attendees by role.
2. Dictate under five headings, saying each one aloud as you reach it:
   • Context: why the session happened.
   • What we heard: attributed to roles ("the CFO said"), not your interpretation.
   • What we think: your hypotheses, clearly marked as yours.
   • Decisions and open questions.
   • Next steps: owner and date for each.
3. Keep each burst short. One heading at a time. Apple Dictation stops after 30 seconds of silence anyway, according to Apple's guide.
4. Type the numbers. Revenue figures, headcounts, percentages and dates are where speech to text slips. A "15%" heard as "50%" changes a recommendation.
5. Read it back against any notes you took in the room. Check every "not", "never" and "only".
6. File it in the engagement's approved workspace, not a personal notes app, if your firm or client requires that.

Try it once with a made-up client before you rely on it: "Northwind Foods, session two. The COO said the Dayton plant runs at about 70 percent of capacity, not 80. We did not agree a pilot site." Count the corrections.

When should a consultant not dictate?

• Open-plan offices and co-working spaces. Speaking a client's name and numbers aloud is a disclosure to whoever is nearby.
• On client premises, unless you are in a private room. Other client staff may not be cleared for what you are saying, especially in a restructuring or deal project.
• Trains, planes, lounges and cafés. Write keywords and dictate the note later.
• Material under heightened restrictions, such as inside information on a transaction, unless the deal team has approved the tool and the place.
• When the client has banned AI tools for the engagement. If your dictation path includes an AI rewriting step, that ban may cover it.

Emails and proposal drafts

Dictation suits the first draft of a proposal's "our understanding" or "approach" section, because those are explanations you have given out loud many times. Dictate into a draft document, then edit for structure; spoken prose is wordier than written prose. For client emails, dictate the body, type the recipient, and read it once for facts and once for tone. Dictate email in Apple Mail and Dictate in Word on a Mac cover the mechanics. Do not reuse another client's material in a proposal without permission; IMC USA's code 5.0 covers that too.

Start with Apple Dictation, then decide

Turn it on in System Settings → Keyboard → Dictation and press the Microphone key in any text field. It is free and Apple says it works "anywhere you can type it". See How to use voice to text on a Mac.

A dedicated app is worth trying if you dictate many short notes a day and want a hold-to-talk key, or if client and product names keep coming out wrong. SuprFlow is one: a menu-bar app for Apple Silicon Macs on macOS 14 or later. Hold Fn, speak, release, and the text is pasted at the cursor. Speech recognition runs on the Mac with a downloaded model, and Default formatting is local cleanup of punctuation, capitalization and numbers. An optional Cloud API mode sends transcript text, not audio, to a provider you choose, which an NDA may not allow, so leave it off for client work unless the engagement permits it. It keeps up to 100 recent transcriptions in local history. It costs $125 once for personal use; firms need separate terms, so contact SuprFlow.

It does not record or transcribe client meetings, so it is no substitute for a meeting transcription tool, which raises its own consent questions. It is Mac only and is not certified against any security standard. Your firm's policy and the client's terms decide what you may use. We have not run a controlled accuracy benchmark against Apple Dictation.

Questions people ask

Can I dictate notes covered by a client NDA?

Only if the whole path fits the NDA: recognition, any AI step, local copies and the destination. Many NDAs restrict sharing with third parties, and a cloud AI provider can be one. Check the clause, and ask the engagement lead if unsure.

Is it better to record the client meeting and transcribe it?

That is a different job with different rules. Recording other people can raise consent questions under local law and the client's terms, and it creates an audio file to protect. Dictating your own notes afterwards avoids recording other people.

Should I let AI turn my spoken notes into a polished summary?

Only with a tool and provider your client terms allow, and read the result against what was said. A fluent summary can harden a hypothesis into a finding.
