Application Of Speech Recognition Technology In The Blind Guidance System

Speech Recognition technology comes out in the field of voice processing technology as a key. The purpose of Speech Recognition is to develop a kind of machine of human auditory function which could understand speech directly and make the appropriate response. Text to speech technology mainly resolves problem is how to text information into voice message. Speech Recognition is playing an important role in the Department of Industrial Production.It becomes more and more urgent to locate ones own vehicles and knows about the road state information. navigation system satisfy this request well. The navigation system usually needs drivers to input the destination with their hands, and speech recognition technology changes this situation. As all effective interaction measures between man and machine, research about speech recognition technology is getting more and more mature and practical. With speech recognition technology applying to navigation systems, drivers can interact to it without their hands, which makes navigation and position more convenient and faster.This paper mainly designed a set of using orientation navigation equipment blind in speech recognition application.First, this paper has a deep study Aitalk 3.0 speech recognition engine use method and development process. Analysis the demand, navigation observer-based cutting force of development board choice embedded hardware platform and custom specific Windows CE operating system; give the speech recognition technology used in the system of navigation observer-based cutting force solution. Finally, based on the scheme a prototype system was implemented. This system is the destination name to voice navigation way, speech recognition results input destination corresponding coordinates; match again, finally passed to the navigation system with voice calls speech synthesis the way to blind broadcasts users. Design speech recognition technology application of embedded into navigation system based on this solution, implementation, and test an application system experiment, validate program speech recognition technology in navigation system application feasibility. Finally, on the basis of summary of this paper, the existing problems of this design have been analyzed, and the direction of further researches has been pointed out.
