Rota AI: Voice Dictation vs Typing — I Tracked My Speed for 2 Weeks
Voice Dictation vs Typing: I Tracked My Speed for 2 Weeks
TL;DR: I tracked every word I wrote for 14 days. Typed vs dictated. Here is what I found. Typing averages around 60-70 WPM for me. Voice dictation averages around 120-150 WPM raw but drops to about 90 WPM after corrections. Voice wins for first drafts and brainstorming. Typing wins for editing, code, and precise text. The best setup is both, used at the right time.
Why I Did This
Ok so I have been using voice dictation almost daily for about six months now. Rota AI, Wispr Flow, Whisper, I have tried them all. And people keep asking me the same question.
"Is voice dictation actually faster than typing?"
My gut said yes. But I did not have real numbers. Just vibes. So I decided to actually measure it for two solid weeks. Typed some days. Dictated some days. Tracked everything.
I am going to share the numbers below. But first, let me explain how I measured.
The Setup
I used a simple method. Not scientific. But consistent.
For typing tasks, I used a stopwatch and a WPM calculator. I would type a passage or write an email, time how long it took, and calculate words per minute. I did this 20 times over the two weeks across different times of day.
For dictation tasks, I used Rota AI on my Windows laptop. Same process. I dictated into emails, notes, blog drafts, and code comments. Timed the entire process, including corrections. Raw dictation speed is fast but you always have to go back and fix stuff. So I measured both: raw speed and final speed after edits.
I used my laptop's built-in mic for the first week. Then I switched to a cheap USB condenser mic for week two. I wanted to see if the mic made a difference. More on that later.
The Numbers
Here is what 2 weeks of tracking gave me.
Typing
- Average WPM: 65
- Range: 55-78 WPM
- Best session: 78 WPM (email to a friend, simple language)
- Worst session: 55 WPM (technical blog post with lots of editing)
- Accuracy: 98%. I type fast enough that errors are rare. When I make them, I fix them instantly.
Voice Dictation (Raw, Before Corrections)
- Average WPM: 140
- Range: 110-165 WPM
- Best session: 165 WPM (brain dump of ideas, just talking freely)
- Worst session: 110 WPM (technical terms and code related stuff)
- Accuracy: 88%. Whisper got most of it right. Errors were usually technical terms and proper nouns.
Voice Dictation (After Corrections)
- Average WPM: 90
- Range: 70-115 WPM
- Best session: 115 WPM (first draft of a blog post, easy corrections)
- Worst session: 70 WPM (dictating code comments, had to fix a LOT)
- Time spent correcting: 20-40% of total time
So yeah. Voice dictation is faster even after corrections. For me, about 40% faster than typing on average. But the story is more nuanced than that single number.
When Voice Dictation Wins
Let me be specific about where voice absolutely destroys typing.
First drafts. This is the big one. When I am writing a first draft of anything, an email, a blog post, notes from a meeting, voice is 2-3x faster than typing. The reason is simple. You think faster than you type. Way faster. When I talk, I just let the words flow. No stopping to think about the perfect word. No backspacing. Just talking. It feels like a brain dump but organized.
I drafted three blog posts during the two weeks using only dictation. Each one took about 15 minutes for a 1000 word draft. Typing that same amount would have taken me 25-30 minutes easily.
Long form content. Anything over 500 words. The longer you go, the bigger the gap. Typing fatigue is real. After 15 minutes of fast typing, my hands start to feel it. After 30 minutes of dictation, I am still going strong. No wrist pain. No hand cramps.
Brainstorming sessions. When I just need to get ideas out of my head and onto the screen, voice is unmatched. I can talk through a whole architecture for a feature in 10 minutes. Typing out the same ideas would take twice as long because I keep stopping to structure the sentences. With voice, I just talk. The cleanup comes later.
Responses and quick messages. Emails, Slack messages, Discord replies. Short, casual stuff. Voice nails this. I can dictate a 50 word response in about 10 seconds. Less than 10 seconds after cleanup. Typing that same message takes maybe 30-40 seconds for me.
When Typing Wins
Now the parts where voice dictation falls apart for me.
Editing. This is the number one case where typing is better, hands down. Editing by voice is painful. I tried to edit a blog post by saying things like "select sentence, delete, type new sentence, move cursor up two lines, capitalize." It was a nightmare. Back to typing in 5 minutes. Even with voice commands, editing is clunky on Windows right now. Maybe Rota AI or another tool will solve this someday. For now, editing is a typing job.
Coding. I wrote a whole blog post about voice coding. It works for comments, docstrings, and boilerplate. But for actual code, typing is faster and more precise. When I need to write get_user_by_email or async def process_request, typing two words is faster than dictating them and hoping it got the casing right. And when it does not get the casing right, the correction takes longer than just typing it would have.
Short bursts. If I only need to type one sentence, like a search query or a quick note, voice is overkill. The overhead of activating dictation, speaking, waiting for transcription, and verifying the text, that is 15 seconds. Typing one sentence takes 5 seconds. For anything under about 20 words, I just type.
Technical content with jargon. When I am writing about things like "voice activity detection" or "Silero VAD" or "Whisper medium model," the error rate goes way up. I spent more time correcting technical terms than I would have spent typing them. For highly technical writing, typing still wins for me.
Noisy environments. This one is obvious but worth saying. If I am in a coffee shop or anywhere with background noise, dictation accuracy drops to like 75%. At that point, it is slower than typing because I am spending half my time fixing transcribing errors.
The Hybrid Approach (What Actually Works)
TBH the real answer is not "voice vs typing." It is both. Used at the right times. Here is what my actual workflow looks like now after these two weeks.
Step 1: Dictate the first draft. I talk through whatever I am writing. Messy, fast, no stopping. Just getting words on screen. This takes maybe 60% of the total time I used to spend typing the whole thing.
Step 2: Type the edits. I go back with keyboard and mouse. Fix the transcription errors. Restructure sentences. Add formatting. Tighten things up. This is the remaining 40% of the time.
Step 3: Dictate comments and notes. Side thoughts, code comments, meeting notes, Slack messages. All dictated. Quick and easy.
The total time savings is significant. For a 1500 word blog post, I used to spend about 45 minutes typing start to finish. Now I spend about 20 minutes dictating the draft and about 15 minutes editing. That is 35 minutes total. A 25% reduction. And honestly the draft quality is about the same because I still do a full edit pass.
That 25% might not sound like much. But over a week of writing, that adds up to 2-3 hours saved. Over a month, that is 8-12 hours. That is a full work day.
Does The Microphone Matter
Yes. More than I expected.
Week one, I used my laptop's built-in mic. Average dictation accuracy was about 85%. Errors were frequent. Lots of misheard words. Correction time was high.
Week two, I plugged in a $25 USB condenser mic. Average accuracy jumped to about 92%. That 7% difference sounds small but it was noticeable in practice. Fewer corrections. Faster overall throughput. My corrected WPM went from about 82 to about 95 just from the mic upgrade.
I want to try a better mic now. A proper XLR setup or something. But the $25 USB mic was already a big jump over the built in one.
What Surprised Me
A few things I did not expect from this experiment.
I got tired of talking. No kidding. After about 45 minutes of straight dictation, my voice felt tired. My throat was dry. Typing has hand fatigue. Talking has voice fatigue. I never thought about that before. The solution is to take breaks, drink water, and mix in typing for editing.
Quiet hours matter. In the mornings when the house is quiet and nobody is around, dictation was smooth. Accuracy was at its peak. In the evenings when my roommates are home and there is background noise, accuracy dropped noticeably. I started doing my heavy dictation work in the morning.
I started thinking differently. This one is interesting. When I type, I think about sentences as I write them. Word by word. When I dictate, I think in paragraphs. I think about the whole idea and then say it all at once. Over two weeks, my brain started shifting. I became better at organizing thoughts before speaking. It was like a weird side benefit. Better verbal communication overall.
The learning curve is real. Week one was rough. I was slow. I kept fighting with the tool. Week two was way smoother. I knew Rota AI's quirks by then. I learned how to speak for better accuracy. I learned what kinds of content work well for dictation and what does not. By the end of week two, my corrected WPM was about 15% higher than in week one. Just from getting used to the flow.
Common Questions
Is voice dictation faster than typing? For most people, yes. Even after corrections, voice is typically 30-50% faster. But it depends on your typing speed and your dictation accuracy. Fast typers (90+ WPM) will see a smaller gap. Slower typers will see a bigger one. your mileage may vary.
What is the best microphone for voice dictation? Your laptop mic works to start. A $20-30 USB condenser mic (the Fifine ones on Amazon) is a massive improvement. A headset mic is great too because it stays at a fixed distance from your mouth. I would not spend more than $30 to get started.
Can I use voice dictation for everything? Not really. Editing, coding, short bursts, and noisy environments are still better with typing. The hybrid approach is the real answer for most people.
Is there a learning curve? Yes. About 1-2 weeks to feel comfortable. About a month to become genuinely fast. Your accuracy improves as the tool learns your voice and as you learn how to speak for dictation.
Does voice dictation cause strain? It can cause voice fatigue if you do it for extended periods. Take breaks. Stay hydrated. Mix in typing for editing passes. It does NOT cause the wrist and hand strain that typing does, so it is a good tradeoff for heavy writing sessions.
What software should I use? On Windows, Rota AI is free and open source. On Mac, Wispr Flow is the easiest option ($10/month). Free alternatives include Whisper via MacWhisper on macOS or Google Docs voice typing. Each has tradeoffs but they all work.
Final Take
Voice dictation is not a gimmick. It is genuinely faster for most writing tasks. But it is not a total replacement for typing. The hybrid approach, dictating drafts and typing edits, is what actually works best.
If you have never tried voice dictation, I would honestly recommend trying it for just one week. Dictate your emails. Dictate your notes. See how it feels. You might hate it. That is fair. But if you are someone who writes a lot for work or school, I think you will be surprised at how much time it can save you.
I will keep tracking. I want to see how these numbers look after a month, after three months. The learning curve suggests things keep getting faster as you adapt. And I have not even tried some of the newer transcription models yet. FR, this space is moving fast.
If you try this yourself, I would love to hear your numbers. Drop me a message or find me on Twitter. Let me know how your voice dictation vs typing experiment goes.
