After many years of effort and work to improve the situation, eliminate barriers in the lives of the deaf, developed the law on sign language. It is defined as a milestone in the struggle to improve their situation. Assistive technology for deaf people an opportunity to communicate their alignment with the rest of society. In the era of computerization there are solutions, offers a chance for the abolition of such barriers. Access to the Internet and mobile devices deaf improve communication with its surroundings.

Real-time speech stretching for supporting hearing impaired schoolchildren

Kupryjanow A., Czyżewski A.

Elektronika : konstrukcje, technologie, zastosowania

2010

Vol. 51, nr 3

24-27

A study of time scale modification algorithms applied to support hearing impaired schoolchildren is presented. Variety of algorithms are considered, namely: overlap-and-add, two variations of synchronous overlap-and-add, and the phase vocoder. Their effectiveness as well as real-time processing capabilities are examined.

W artykule przedstawiono przegląd algorytmów służących do modyfikacji czasu trwania mowy oraz analizę możliwość ich zastosowania do celu wspomagania procesu rozumienia mowy u dzieci w szkole. Zbadano następujące algorytmy: overlap and add, dwie odmiany algorytmu synchronous overlap and add oraz wokoder fazowy. W części eksperymentalnej zbadano skuteczność działania algorytmów oraz ich złożoność obliczeniową.
