SonicASL Sign-to-Speech Headphones Introduced

A research team led by scientists from the University of Buffalo modified the headset with

noise cancellation system, which allowed the electronic device to "see" and translate sign language paired with a smartphone.

The system, dubbed SonicASL, showedefficiency 93.8% in tests conducted indoors and outdoors and included 42 words. Examples of used vocabulary: "love", "space" and "camera". Under the same conditions, using 30 simple sentences - for example, "Nice to meet you" - SonicASL performed 90.6%.

There is still a lot of work to be done beforethe technology will be able to enter the market as a commercial product, the researchers emphasized. For example, you need to significantly expand your SonicASL vocabulary. In addition, the system must be able to read facial expressions, which is an important component of sign language.

Researchers intend to continue working oncreating a system. Their main motive is that there are over 72 million people with hearing impairments worldwide. They all have difficulty communicating with other people. The task is very difficult because deaf people around the world deal with over 300 different sign languages.

According to the researchers, in the inventionuses Doppler technology to “feel” tiny vibrations or echoes in the acoustic waves generated by hand movement. The results of the study will be presented at the ACM Conference on Ubiquitous Computing (UbiComp), which will be held from 21 to 26 September.
