People could use breath to 'speak' LONDON: A first of its kind device that transforms paralysis victims' breath into words has been developed by researchers, including one of Indian origin. 

The prototype developed by researchers from Loughborough University analyses changes in breathing patterns and converts 'breath signals' into words using pattern recognition software and an analogue-to-digital converter. A speech synthesizer then reads the words aloud. The device learns from its user, building up its knowledge as it goes. 

It allows the user to control how he or she wishes to communicate - effectively enabling them to create their own language by varying the speed of their breathing.
