Dictating Documentation: A Developer's Honest Take

No developer I know enjoys writing documentation. The code is done, the problem is solved, and now you have to explain it in plain language to someone who was not in your head for the last four hours. It feels like a tax on finishing.

Voice dictation does not make documentation enjoyable. It does make it fast enough that the excuse to skip it gets harder to justify.

Where Developers Actually Lose Time

The slow part of writing documentation is not thinking of what to say. Most developers know exactly what a function does, what its parameters mean, and what will break if you misuse it. The slow part is the transition from knowing to writing.

Typing forces you to slow down to roughly 60 words per minute and encode your knowledge one character at a time. Speaking lets you explain a function the same way you would explain it to a colleague over Slack voice chat. That explanation, captured and lightly cleaned up, is usually 80 percent of the documentation you need.

A Practical Workflow

Open the file you need to document. Position your cursor in the docstring or comment block. Press your dictation key, explain the function out loud as if talking to a junior developer, and release.

With VoiceInk, the transcription appears directly in your editor with no copy-paste step. The output will need minor cleanup: punctuation adjustments, maybe a sentence reordered. That cleanup takes 90 seconds. The alternative is a blank docstring that stays blank for three weeks.

For longer documentation, like a README or an architecture overview, speak one section at a time. Treat each section like a short voice message to a future teammate. Informal is fine. Clear is what matters.

Inline Comments While You Work

One use case that developers often overlook: dictating inline comments in real time, while the reasoning is fresh.

When you write a non-obvious piece of logic, speak the comment immediately. "This handles the edge case where the input array is empty after filtering, returning null instead of throwing." That takes four seconds to say. It would take twenty seconds to type, and most people skip it and move on.

Comments written in the moment are more accurate than comments written after the fact because you have not yet closed the mental context. Voice makes the in-the-moment comment fast enough to actually do.

What Voice Does Not Replace

Be straightforward about the limits. Dictation is not useful for writing code itself. Syntax is too precise, variable names too specific, structure too dependent on indentation and characters that are awkward to speak. Trying to dictate Python or JavaScript is not the move.

It is also not ideal for very short labels, function names, or anything requiring exact spelling of custom terms. For those, the keyboard is faster.

The sweet spot is natural language: comments, docstrings, READMEs, internal wiki pages, Slack messages explaining a technical decision, notes to yourself in a scratchpad file.

The Documentation Backlog Problem

Most developers have a mental list of things that should be documented and are not. Functions written in a hurry, architectural decisions that live only in one person's memory, setup steps that every new team member has to ask about.

Voice makes it possible to burn through that backlog quickly. Set 30 minutes aside, open the files, and talk through each thing you know. You will produce rough documentation for five or six functions in the time it used to take to write one clean docstring.

Rough documentation that exists is more valuable than perfect documentation that does not.

If documentation is a habit you have been meaning to build, trying it with voice first lowers the activation energy enough that the habit might actually stick.
