Ten years ago, speech to text felt like a gimmick to most people. In late 2022, ChatGPT made AI writing mainstream. By 2026 the two overlap: dictation apps now use language models to clean up what you say.
So a practical question comes up: which workflow gets a message written faster?
- Typing a rough draft and asking ChatGPT to rewrite it?
- Speaking a rough draft and letting a dictation app like LumeVoice clean it up?
For your own messages, speaking usually wins. Here's why, and where AI writing still earns its place.
The Efficiency Gap#
Typing + Generative AI#
- Input speed: about 52 words a minute for an average typist, according to an Aalto University analysis of 136 million keystrokes.
- Workflow: Type the draft. Copy it. Open ChatGPT. Write a prompt ("make this sound professional"). Wait. Copy the result. Paste it back. Check it still says what you meant.
- Cost: two app switches, a prompt to write, and a rewrite to check.
Voice + AI Cleanup (The LumeVoice Way)#
- Input speed: conversational speech runs at about 120–150 words a minute.
- Workflow: Click into the text box. Hold the dictation key (fn on Mac, Ctrl + Win on Windows). Say what you mean. The cleaned-up text is typed where your cursor is.
- Cost: no app switching, no prompt, and the words are still yours.
The research points the same way: a Stanford, University of Washington and Baidu study found speech input about three times faster than typing on a smartphone keyboard, with fewer errors.
Why Speaking Can Help You Draft#
When you type, it's easy to slip into editing mode. You hesitate. You delete words before you finish the sentence. You lose the thread.
When you speak, you tend to keep going. You say the point, stress what matters and get the whole idea out. A dictation app with a cleanup step then does the tidying: filler words removed, self-corrections applied, grammar and punctuation fixed, spoken lists turned into numbered lists.
That's how many people experience it, not a law. Some people think better with their fingers on the keys. Try both on a real email and see which gets you to a finished draft sooner.
Write like you think.
LumeVoice's cleanup step is built for this workflow. It skips the ChatGPT middleman: say what you mean, and clean text appears right where your cursor is.
Where AI Writing Still Wins#
ChatGPT and similar tools are excellent at things dictation doesn't try to do:
- Brainstorming when you don't know what to say yet.
- Summarising long documents and threads.
- Restructuring a draft: turning notes into an outline, or a long email into three bullet points.
- Boilerplate and translation, where the exact wording isn't personal.
- Generating code from a description.
For daily communication, though (Slack, email, Notion docs), the copy-paste loop is a real context switch, and the result is the AI's wording rather than yours. AI-generated text can also state things that aren't true, so it needs checking in a way your own words don't.
How to Use Them Together#
You don't have to pick one:
- Dictate the draft, then ask an AI to restructure it when the structure needs work.
- Dictate your prompts. Detailed prompts get better answers, and speaking one is quicker than typing it. LumeVoice types into whatever app has your cursor, including the ChatGPT or Claude chat box.
- Dictate your edits. Read the AI's version, then say the changes you want in your own words.
The Verdict#
If you're typing drafts and feeding them to ChatGPT just to make them sound right, try dictating them with a cleanup step instead: you skip the round trip and keep your own voice. Keep AI writing for what it does best: generating, summarising and restructuring.
Brain, voice, finished text. Stop typing. Start talking.
Frequently Asked Questions
Is it accurate enough?
For most everyday writing, modern speech models are accurate enough that you fix a word here and there rather than retype. Accuracy depends on your microphone, the room, your accent and your vocabulary, so add names and jargon to a custom dictionary and read anything important before you send it.
What about privacy?
Check each tool's policy. AI chat services have their own data settings, and some may use your conversations to improve their models unless you opt out. LumeVoice processes speech in the cloud, doesn't store your audio after processing, keeps your transcription history on your device and never uses what you say to train a model.
Can I dictate prompts into ChatGPT?
Yes. LumeVoice types into whatever app has your cursor, so you can speak a prompt into ChatGPT, Claude or any other chat box as easily as an email.
What does LumeVoice cost?
Every new account gets 3,000 free words, no card required. Plans are $14.99/mo, $79.99/yr, or $249 lifetime, with a 7-day free trial when you first upgrade in the app (card required).
