Dictating Documentation: A Developer's Honest Assessment

Documentation is the work that doesn't feel like work until it doesn't exist. Every developer knows the feeling: the feature is shipped, the PR is merged, and now someone has to explain what it does and why. That someone is usually you, and the keyboard suddenly feels heavier than usual.

Voice dictation doesn't solve the problem of wanting to write documentation. But it does remove most of the friction involved in actually doing it.

Where Voice Fits in a Dev Workflow

Let's be specific. Voice dictation is not useful for writing code. Dictating variable names, brackets, function signatures, and syntax is slow and error-prone. The keyboard is faster there, and it always will be.

Where voice earns its place is everything around the code.

README files. Architecture decision records. Inline comments explaining why a piece of logic exists. Slack messages to your team. Tickets describing a bug. Onboarding docs for new engineers. All of these are prose, and prose is exactly where speaking outperforms typing.

The Comment Problem

Inline comments are the most underdocumented part of most codebases. Not because developers don't understand the code, but because stopping to type a three-sentence explanation while you're in flow is annoying enough that it gets skipped.

With a tool like VoiceInk, you can leave your hands on the keyboard, trigger dictation with a shortcut, speak the comment, and continue. The transcription is local and fast enough that it doesn't break your rhythm the way switching to a browser or documentation tool does.

Trying it looks like this: you finish writing a function, you see a part that will confuse the next person, you press your shortcut, say "this timeout exists because the third-party API returns a 200 before the data is actually ready, we found this in production in March," and then you're back to coding. That comment took eight seconds.

Writing READMEs by Talking

A good README is a spoken explanation written down. Think about how you'd describe your project to a new teammate over coffee. That's exactly what a README should sound like.

So write it that way. Literally. Open a blank document, press your dictation shortcut, and explain your project out loud as if someone asked you about it. Don't stop to edit. Get the whole explanation out.

What you'll have is rough, but it will be complete. The structure will be there. The tone will be approachable. Cleaning it up takes ten minutes. Starting from a blank page, by typing, often takes much longer because you're writing and editing at the same time.

Architecture Notes and Decision Logs

The most valuable documentation in any long-lived codebase is the stuff that explains decisions. Why did you choose Postgres over MongoDB? Why is the authentication handled here and not there? Why does this service exist separately?

These explanations live in people's heads and disappear when they leave. Getting them into text is the problem.

Voice makes this faster because the explanation already exists in your head as speech. You've given this explanation in meetings. You've said it on calls. Recording it by dictating takes the same amount of time as saying it, which is much less than typing it.

What to Expect at First

The first few times you dictate technical prose, you'll speak too quickly or lose your place. That's normal. After a handful of sessions, you'll develop a pace that works: deliberate, complete sentences, short pauses between thoughts.

Accuracy on standard English prose is high with local models. Technical terms and proper nouns occasionally need correction. That's a quick fix on review.

The time you save on first draft output more than covers the time spent on corrections.

The Bottom Line

Documentation doesn't get written because it's slow and unrewarding. Voice dictation makes it faster. The reward part is still up to you, but removing the friction is enough to move the needle.

If your codebase is missing docs you know should exist, try talking them into existence. The results might surprise you.
