Voice typing vs typing: how much time do you actually save?

The average person speaks at roughly 150 words per minute and types at roughly 40. Even after you subtract the time spent fixing recognition errors, dictating first drafts is commonly two to three times faster than typing them. The savings are real, but they are not uniform: dictation shines on prose and loses to the keyboard on short bursts, code, and heavy editing. Here is where the math actually lands.

What do the raw numbers say?

Take a 400-word email or status update. At 40 words per minute of sustained typing (and most people dip below that once they start re-reading and re-phrasing mid-sentence), that is about ten minutes of keys. Speaking the same text at a relaxed pace takes under three minutes, plus a minute or two of correction. You save five to seven minutes on one email. Multiply by the number of substantial messages, tickets, and comments you write in a day and the hours add up fast.

There is a subtler win underneath the speed: speaking separates composing from transcribing. When you type, part of your attention is spent on the mechanics of getting words onto the screen. When you speak, you just think out loud. Many people find their dictated drafts are more natural and complete for exactly this reason.

Run the weekly version of the math. If you save six minutes on each of ten substantial messages a day, that is an hour a day, or five hours a week, returned to work that is not typing. Even a conservative half of that is two and a half hours a week: a hundred-plus hours a year.

Where does dictation win?

Dictation earns its keep anywhere the output is sentences.

• Email and chat replies longer than a couple of lines.
• Documentation, specs, and ticket descriptions, where the first draft is the hard part.
• Form fields and applications: repetitive, boring, and exactly the kind of typing that makes hands ache.
• Brain dumps and outlines. Talking through a messy idea and editing the transcript is faster than staring at a blank page.
• Any day your hands are tired, injured, or busy. Speed is not the only currency here.

Where does the keyboard still win?

Honesty matters more than hype, so: dictation is not always faster.

• Very short inputs. A two-word search query or a "thanks, on it" reply is faster to type than to click a mic and speak.
• Code, commands, and anything dense with symbols. Saying "open brace" fifty times is nobody's idea of fun.
• Precise editing. Selecting a word and retyping it beats dictating around it, so plan to dictate the draft and type the fixes.
• Shared or silent spaces. Open offices, libraries, and late-night households impose a social tax no model can fix.
• Passwords and secrets, for obvious reasons. Never dictate those.

How much correction time should you expect?

Modern speech models are good enough that a clear voice in a quiet room produces a mostly clean transcript, punctuation included if you speak it. The realistic correction load is a wrong word or two per paragraph, plus a formatting pass. A quick proofread is non-negotiable for anything formal, but proofreading a transcript is still much faster than having typed the whole thing.

Two habits cut correction time dramatically: dictate in bursts of one or two sentences rather than long monologues, and use a decent microphone. A $30 headset outperforms a laptop mic by enough to notice on the first day.

What about accuracy and privacy?

tautau routes your audio to hosted speech models (xAI Grok STT, with failover to Groq or OpenAI Whisper) purely to produce a transcript. Audio is not used for training and not sold; without an account nothing is retained beyond the request. Accuracy-wise, these models handle accents, filler words, and spoken punctuation well, and the failover means a slow provider does not become your problem.

So is it worth it?

If you write more than a few substantial messages a day, yes. Keep the keyboard for the quick stuff and the precise edits, and speak everything else. The free tier on tautau gives you five dictations a day signed in, which is exactly enough to run your own experiment: dictate your next three emails and compare the clock. The mic button appears in every text field on the web, so the experiment takes no setup beyond installing the extension. Your 150 words per minute have been waiting for this.
