When is typing better than dictation?

Typing is better when the words need to be exact, when the change is small, or when speaking would be out of place. The keyboard is the safer choice for code, tables, names, punctuation-heavy text, precise edits to a dictated draft, and any room where other people can hear you. Dictation is better for getting volume onto the page quickly. The dictation vs typing guide sets out the full comparison.

Small corrections are faster with keys

Dictation is strong at producing words and weaker at changing them. When you correct a dictated error by speaking again, the correction can fail too. Vertanen found that spoken corrections are often misrecognized, which costs time and patience ¹. A swapped name, a changed comma or a word in the middle of a paragraph is often quicker to fix with the keyboard and a cursor.

The studies behind dictation's speed also show where the cost falls. In the phone study, speech made fewer errors during entry, but it left slightly more errors in the final text: 1.30 percent uncorrected against 0.79 percent on the keyboard ². Those leftover errors are the ones you must find by hand, and the keyboard is the tool for fixing them. The guide to proofreading dictated text covers the check. Words that sound alike are one source of these errors, as the homophone entry explains.

Code, symbols and tables suit the keyboard

Code is dense with brackets, quotation marks, operators and names that a recognizer has not seen. Spoken punctuation covers the common marks, as the dictation punctuation guide explains, but it does not cover every symbol you need in code. This point is a judgment from how code is written. None of the studies in this guide measured dictation of code.

Tables are similar. A keyboard moves from one cell to the next with a single key, while a dictated command must name each move. For dense grids, typing is the simpler route. The dictation commands guide lists the voice commands that do help with navigation, if you want to keep speaking.

Quiet and shared rooms favor typing

Dictation is spoken aloud, so it has a social cost in an open office or a shared room. The authors of a study of open-plan offices write that it seems accepted that speech noise in those offices is the main source of discomfort for employees ³. That is the authors' view of accepted practice, not a measured share, so it does not show how colleagues will react to your voice. It does help explain why shared rooms are a poor place to speak aloud.

Background noise is also a concern for recognition. Apple advises that a headset microphone may help when Dictation is used in a noisy environment or a room with excessive echo ⁴. Apple gives no accuracy figures for that advice, so it is a starting point. The dictation and background noise guide covers the room side in more detail.

Connection and processing can rule dictation out

Some dictation engines need an internet connection. Windows voice typing needs one, along with a working microphone and a cursor in a text box ⁵. On a Mac, Apple says that general text Dictation is processed on your device ⁶, but its help page also says Dictation may need an internet connection ⁷. The two statements can both be true depending on settings and language, so the Keyboard settings on your Mac show which is in effect. If you cannot rely on a connection, keep the keyboard as the default for that work.

What to do: keys for precision, voice for volume

The practical rule is simple. Speak to get words down, and switch to the keyboard when the text must be exact, dense or quiet.

1. Keep typing for code, tables, names, numbers you must get right and small edits.
2. Dictate the first draft of prose, messages and notes, where getting words down matters most.
3. Type the proofread with the cursor, not by repeating corrections aloud.
4. Test on your own work. The question on whether dictation is faster than typing explains how to compare the two on the same piece of writing.

Typing is not always better, and dictation is not always faster. The studies here use short phrases, laboratory conditions and older recognizers, so your own writing is the final test. For whether you can mix the two in one session, see can you dictate and type at the same time. For the wider topic, see the dictation topic overview.
