Machines out perform humans in lip reading

Machine accuracy - 80 %; Humans - 32%

More than half of people over 60 have a hearing loss (I am in that group). The demand for lip reading skills is driving technology. I foresee that we will soon have portable devices that will "read lips" and either show the words on a display or if the person is deaf and blind it could produce tactile symbols (braille) on a touch pad.

A research team from the School of Computing Sciences at UEA compared the performance of a machine-based lip-reading system with that of 19 human lip-readers. They found that the automated system significantly outperformed the human lip-readers – scoring a recognition rate of 80 per cent, compared with only 32 per cent for human viewers on the same task.

Better virtual "talking heads", too

By analyzing results of computerized recognition of facial speech patterns, researchers hope to produce better visual speech synthesis. Computer generated "talking heads" are being evaluated to create the most intelligible and visually appealing system.

Machine Manufacturing's picture

This is great news for people with hearing loss as with improved technology in lip reading can make communication easy for them.
