LONDON, UK: In a breakthrough research, the scientists at the University of East Anglia (UEA) in Norwich, England, have created lip-reading computers that can distinguish between different languages.

Computers that can read lips are already in development but this is for the first time they have been ‘taught’ to recognize different languages, said the researchers. They hope the discovery could have practical uses for deaf people, for law enforcement agencies, and in noisy environments.

The research was led by Stephen Cox and Jake Newman of UEA’s School of Computing Sciences. The technology was developed by statistical modeling of the lip motions made by a group of 23 bilingual and trilingual speakers.

The system was able to identify which language was spoken by an individual speaker with very high accuracy. These languages included English, French, German, Arabic, Mandarin, Cantonese, Italian, Polish and Russian, they claimed.

“This is an exciting advance in automatic lip-reading technology and the first scientific confirmation of something we already intuitively suspected, that when people speak different languages, they use different mouth shapes in different sequences,” said Prof Cox.

“For example, we found frequent ‘lip-rounding’ among French speakers and more prominent tongue movements among Arabic speakers.”

Funded by the EPSRC, the research is part of a wider UEA project on automatic lip-reading. The next step will be to make the system more robust to an individual’s physiology and his or her way of speaking, said the researchers.
