I Replaced My Keyboard with My Voice for a Week

The Challenge

I type for a living. As a developer and technical writer, I spend 6-8 hours a day with my hands on a keyboard. That is roughly 50,000 keystrokes per day, five days a week.

For one week, I decided to replace as much keyboard typing as possible with voice typing. Not for code — I am not a masochist — but for everything else: emails, Slack messages, documentation, AI prompts, notes, search queries, and anything that involves writing prose.

The tool: Murmur, with its Ctrl+Space shortcut. The rules: use voice for all text input except actual code, terminal commands, and file paths. The goal: find out if voice typing is a real productivity tool or just a gimmick.

Here is what happened.

Day 1 (Monday): Setup and Self-Consciousness

Voice typing attempts: 23 Times I accidentally typed instead: 11 Estimated time saved: negative (slower overall)

The setup was easy. Murmur installed in about a minute, and the shortcut worked immediately. The technology was not the problem. My brain was.

Every time I reached for Ctrl+Space instead of just typing, a small part of my brain resisted. Typing is so deeply habitual that choosing to speak instead felt like using my non-dominant hand. I knew what I wanted to say, and the fastest path from thought to text — the one my muscles had memorized over two decades — was the keyboard.

The first email of the day took longer by voice than it would have by typing. Not because the dictation was slow, but because I kept stopping myself mid-sentence, unsure if I was speaking clearly enough or if I should restructure my thought first.

By the afternoon, something started to shift. I stopped planning my sentences before speaking and just... talked. The emails started flowing faster. A three-paragraph response to a product question took about 45 seconds of speaking versus my usual 3-4 minutes of typing and editing.

Day 1 verdict: Frustrating start, but glimpses of potential.

Surprise of the day

Murmur's AI transcription accuracy genuinely impressed me. The output was clean and natural-sounding from the start, whether I was writing a quick Slack message or a longer email. The AI processing produced well-formatted text that needed minimal editing.

Day 2 (Tuesday): The Slack Revelation

Voice typing attempts: 41 Times I accidentally typed instead: 6 Estimated time saved: 25 minutes

Slack is where voice typing starts making obvious sense. I usually spend 30-45 minutes per day typing Slack messages. Today, I voice-typed every response longer than five words.

The results were immediate. Instead of typing, pausing, re-reading, and occasionally rewriting, I just said what I meant and moved on. A standup update that normally takes a minute to compose took about 10 seconds:

"Yesterday I shipped the notification service refactor and fixed two flaky tests. Today I'm working on the API rate limiting middleware. No blockers."

That came out perfectly on the first try. No edits needed. Ten seconds of talking versus sixty seconds of typing.

By the end of the day, I had cleared my Slack backlog in roughly half the usual time. The key insight: Slack messages are conversational, and speaking is the natural way to produce conversational text.

Day 2 verdict: Voice typing is a clear win for messaging apps.

Mistake of the day

I tried to voice-type a code review comment that included a variable name: userAuthenticationMiddleware. What I got: "user authentication middleware." No camelCase, no single-word formatting. For technical terms that need exact formatting, the keyboard is still necessary.

Day 3 (Wednesday): Email Flow State

Voice typing attempts: 38 Times I accidentally typed instead: 3 Estimated time saved: 40 minutes

Today I processed my entire email inbox by voice. Twenty-two emails, ranging from one-sentence confirmations to multi-paragraph responses.

Something unexpected happened: my emails got better. When typing, I tend to over-edit. I write a sentence, delete half of it, rewrite it, and end up with something that sounds careful but stilted. When speaking, the words come out in a natural flow that sounds more human and, frankly, more like me.

One email — a response to a frustrated user about a bug — came out especially well via voice. I spoke empathetically and directly, and the transcription captured that tone perfectly. If I had typed it, I would have spent ten minutes carefully choosing words to avoid sounding dismissive or overly apologetic. Instead, I just talked like a human being for thirty seconds.

Day 3 verdict: Voice typing does not just save time — it produces more natural-sounding text.

Frustration of the day

Phone notifications. When my phone buzzed, Murmur picked up the notification sound and the transcription got confused for a second. I started keeping my phone on silent during voice typing sessions.

Day 4 (Thursday): Documentation Day

Voice typing attempts: 29 Times I accidentally typed instead: 2 Estimated time saved: 55 minutes

Thursday is documentation day on our team. I usually dread it. Writing technical documentation by keyboard is slow, tedious, and draining.

Today, I tried a hybrid approach: outline by keyboard, then dictate each section by voice. The outline gave me structure. Voice gave me speed.

The result surprised me. I wrote documentation for two API endpoints, a setup guide for new contributors, and a troubleshooting FAQ — all by lunch. Normally, the API endpoint docs alone would take the full morning.

The dictated docs needed more editing than the emails and Slack messages. Technical writing has specific conventions (numbered steps, code references, precise terminology) that voice does not capture perfectly. But even with editing, the total time was about 40% less than pure typing.

Day 4 verdict: Voice + keyboard hybrid is the sweet spot for technical documentation.

Discovery of the day

I started using voice typing for my AI prompts (to Claude and ChatGPT), and it completely changed how I interact with AI tools. Instead of carefully composing prompts by keyboard, I explained what I needed conversationally. The prompts were longer, more detailed, and more natural — and the AI responses were better because of it.

Day 5 (Friday): The Productive Calm

Voice typing attempts: 44 Times I accidentally typed instead: 1 Estimated time saved: 50 minutes

By Friday, something had changed in my workflow that I had not anticipated: I was calmer.

This sounds like wellness blog nonsense, so let me be specific. When typing for hours, there is a constant low-level physical tension — wrists engaged, fingers poised, shoulders slightly forward. By switching half my text input to voice, that tension was cut significantly. My hands got regular breaks without stopping work.

I found myself taking fewer "need to rest my hands" breaks because my hands were not tired. The total time at my desk was about the same, but the physical strain was noticeably less.

The workflow was now second nature: Ctrl+Space for anything longer than a short sentence, keyboard for code and formatting. No hesitation, no mental overhead deciding which to use.

Day 5 verdict: The ergonomic benefit is an underrated part of voice typing.

Weekend Reflection

Over the weekend, I did some personal typing — a long email to a friend, some Reddit comments, a blog post draft — and found myself reaching for Ctrl+Space by reflex. The habit had formed in five days.

Day 6 (Monday): Back with Perspective

Voice typing attempts: 47 Times I accidentally typed instead: 0 Estimated time saved: 55 minutes

Returning to work after the weekend, I had perspective on what voice typing changed and what it did not.

What changed:

• Email and Slack are dramatically faster
• Documentation is faster (hybrid approach)
• AI prompting is more natural and produces better results
• Physical strain is reduced
• I feel less drained at end of day

What did not change:

• Code is still typed (obviously)
• Very short inputs (search queries, file names) are still typed
• Meetings are unchanged (voice typing is for text input, not transcription)

The time savings were real but not evenly distributed. Some tasks saw 60%+ improvement, others were basically unchanged.

Day 7 (Tuesday): The Verdict

Voice typing attempts: 51 Times I accidentally typed instead: 0 Estimated time saved: 60 minutes

Seven days in. The experiment is over. Here is the honest assessment.

What I Am Keeping

Voice for emails. This is the biggest win. I process email in about a third of the time, and the quality of my responses is arguably better. This alone justifies the experiment.

Voice for Slack. Same logic as email. Conversational input for a conversational medium.

Voice for documentation. The hybrid approach (outline by keyboard, dictate content by voice, edit by keyboard) is significantly faster than pure typing.

Voice for AI prompts. This was an unexpected benefit. Speaking prompts produces more detailed and natural instructions.

What I Am Not Keeping

Voice for code-adjacent text. Variable names, file paths, terminal commands, and inline code are still faster to type.

Voice for very short inputs. Search queries, file names, and one-word responses are not worth activating voice typing for.

Voice in meetings. I tried voice-typing notes during a call and it was awkward. Taking notes after the meeting by voice works better.

The Numbers

The Final Verdict

Voice typing is not a gimmick. It is not going to replace your keyboard. But for prose-heavy tasks — email, messaging, documentation, writing — it saves real time and reduces physical strain.

The AI-powered accuracy matters more than I expected. Without it, I would have spent the time savings on editing transcription errors. With Murmur, the output is clean and accurate from the start, which is what makes the speed gain stick.

Would I recommend this experiment? Absolutely. You do not need to go all-in for a week like I did. Just start with emails for one day. Voice-type every email. Time yourself. Compare it to yesterday. The numbers will convince you faster than any article can.

Tips If You Try This Yourself

1. Start with your most painful text input. For me, it was email. For you, it might be Slack, documentation, or AI prompts.
2. Use a headset. Not for audio quality, but to make voice typing feel more natural. Talking into thin air feels weird. Talking into a headset mic feels like a phone call.
3. Give it three days. Day 1 is awkward. Day 2 is better. Day 3 is when the habit starts forming.
4. Do not force it for everything. The hybrid approach (voice for prose, keyboard for code and formatting) is better than trying to voice-type absolutely everything.
5. Measure your time. Without numbers, you will not believe the improvement. Track time for your five most common text tasks before and after.
