Composing texts with smartphone speech recognition is 3 times faster than typing, and more accurate

Post by Ben Reilly on Wed Aug 24, 2016 10:19 pm

Smartphone speech recognition software gets a bad rap. Most users find the nascent technology to be frustratingly slow, and there are entire blogs dedicated to documenting examples of its biggest – and sometimes hilarious – mistakes.

But results from a new experiment suggest a different reality: Speech recognition can be used to compose text messages faster and more accurately than humans can type on mobile phone screens.

“Speech recognition is something that’s been promised to us for decades, but it has never worked very well,” said James Landay, a professor of computer science at Stanford and co-author of the new study. “But we were noticing that in the past two to three years, speech recognition was actually improving a lot, benefiting from big data and deep learning to train its neural networks to produce faster, more accurate results. So we decided to formally test it against humans.”

The research team, which included computer scientists from Stanford, Baidu Inc. and the University of Washington, devised an experiment that pitted Baidu’s Deep Speech 2 cloud-based speech recognition software against 32 texters, ages 19 to 32, working the built-in keyboard on an Apple iPhone.

“They grew up texting, so we’re putting speech recognition up against people who are really good at this task,” Landay said.

The subjects took turns typing or speaking about 100 phrases sourced from a standard library of everyday phrases used in text-based research – phrases such as “physics and chemistry are hard,” “have a good weekend” and “go out for some pizza and beer” – while the testing app recorded their times and accuracy rates. Half the subjects performed the task in English using the QWERTY keyboard; the other half conducted the test in their native Mandarin using iOS’ Pinyin keyboard.

The results were clear no matter the language. For English, speech recognition was three times faster than typing, and the error rate was 20.4 percent lower. In Mandarin Chinese, speech was 2.8 times faster, with an error rate 63.4 percent lower than typing.

I find shortcuts for every mundane task I can manage, so I can spend more time on things I care more about.

Well you can't argue with logic I suppose Ben.

For example, searching for whether it's possible to get an AI member for your forum. (It appears not, but wouldn't that be cool?)

You have a strange way of calming things down.
Yes, it would be cool. geek

it works well if you calibrate it for your voice. they are gettign better at having broader calibration.

the biggest issue used to be that you had to speak with an american accent to get it to work.
