Speaking vs typing: how much faster is your voice?
Most of us type to our phones with two thumbs, even for a one-line question. A study from Stanford measured what speaking instead would save. Speaking turned out almost three times faster, in a quiet lab.
In short. In a 2017 study, people entered short English messages almost three times faster by voice than on a phone keyboard: 153 words a minute against 52. Voice made fewer errors along the way but left slightly more in the final text. It was a quiet lab, and people copied set sentences rather than writing their own. Voice wins for quick, simple things; typing still wins in a crowd, in noise, and for careful edits.
What the study did
Sherry Ruan, Jacob Wobbrock, Kenny Liou, Andrew Ng and James Landay compared speech recognition with the built-in keyboard of an iPhone 6 Plus, in English and in Mandarin Chinese. Participants copied short phrases, once by voice and once by typing, in a laboratory. The speech recogniser was Baidu’s Deep Speech 2, one of the deep-learning systems of the time.
What it found
| Voice | Keyboard | |
|---|---|---|
| English, words a minute | 153 | 52 |
| Mandarin Chinese, words a minute | 123 | 43 |
| Errors made and fixed along the way | 5.3% | 11.2% |
| Errors left in the final text | 1.3% | 0.8% |
Speech was 2.93 times faster in English and 2.87 times faster in Mandarin.
What it did not measure
- Writing your own words. Copying a given sentence is faster than thinking one up, by voice or by hand.
- Real life. No street noise, no wind, no people listening. The authors themselves call for studies outside the lab.
- Today’s systems. Speech recognition and keyboards have both changed since; the study compares the best of 2016.
When voice wins, and when typing does
| Voice is better for… | Typing is better for… |
|---|---|
| a quick question or a short reply | anything private in a crowded place |
| a note or a reminder while your hands are busy | a noisy street, a café, a concert |
| times when looking at a screen is the problem | careful edits, names, numbers, code |
| people who find small keyboards hard | quiet places where talking would disturb others |
The social side, talking to an AI where others can hear: talking to AI in public.
Why our ring is built around voice
A ring has no room for a keyboard, and that is the point: the things you reach for a phone to type are usually short. Lychnos Ring is designed so you hold its button and speak, see the first line of the answer on its screen and hear the rest, and press once to approve anything it would send. How well speech recognition copes with a microphone on your hand: can a ring understand a mumble? Why a button and not a wake word: hold to talk. It is in development.

Questions
Is speaking faster than typing on a phone?
In a laboratory study published in 2017, yes: people entered short English messages 2.9 times faster by voice (153 words a minute) than with the phone's keyboard (52 words a minute). Mandarin Chinese was 2.9 times faster too.
Is voice typing more accurate than a keyboard?
It is mixed. In the same study, voice made fewer errors along the way, but left slightly more in the finished text: 1.3% against 0.8%.
