Research on Barrier-free Home Environment System Based on Speech Recognition

The number of physical disability increased year by year, and the trend of population aging is more and more obvious. In order to improve the quality of their lives, we applied user speech signals as control information source to carry out a research on barrier-free home environment system based on speech recognition, including central control platform, speech recognition module, operate terminal nodes etc. The system combines the speech recognition control technology, wireless information transmission technology with embedded mobile computing technology and interconnects the lamp, electronic locks, alarms, TV and other electrical devices as a system in the home environment through a wireless network node, and the speech recognition success rate is more than 80% in the home environment after the system test.
