Development and Evaluation of Voice Recognition Input Technology in Navigation System for Blind Person

This paper describes a navigation system for a blind person that uses an audio guidance system including input from a voice recognition system. The proposed voice recognition system is used in order to easily set the desired destination for the blind person. By using the proposed voice recognition system, the destination can be set by using a microphone. An EasyVR module is used to develop the voice input navigation system. In order to measure the performance of the developed system, the user’s voice is evaluated by using the template matching method. Some experiments on the proposed voice input navigation system are also conducted at different locations with different sound intensity levels. As a result, the satisfactory performance of the developed voice navigation system is confirmed.
