Smartphone speech recognition software can compose text messages up to three times faster and more accurately than humans can type, a new study has found

A COMMON MYTH
Most users find current speech recognition softwares to be frustratingly slow, and it is often inaccurate
However, the new study suggests a different reality
THE STUDY
The research team, which included scientists from the University of Washington, devised an experiment that pitted a cloud-based speech recognition software against 32 texters, ages 19 to 32 using the built-in keyboard on a smartphone
THE UNDERLYING TEXT
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 keyboard
WHAT THEY FOUND
For English, speech recognition was three times faster than typing, and the error rate was 20.4% lower
In Mandarin Chinese, speech was 2.8 times faster, with an error rate 63.4% lower than typing
THE ADVANTAGE
The researchers have quantified that speech recognition actually works well, they hope it will encourage engineers to design user interfaces that take better advantage of the technology
