A Speech Recognition Method for Navigation Destination Based on Phoneme

In order to improve the interaction security and efficiency of in-vehicle navigation device,solve the low accurately problem of ordinary speech recognition technology,based on analyzing the voice control function of in-vehicle navigation device,a speech recognition solution for navigation target on the basis of phoneme was put forward.In order to make the solution come true,the query character string matching algorithm for the interaction between alphabet and navigation electronic map was designed.By selecting Microsoft Speech SDK 5.1 as speech recognition engine,based in navigation data of Changchun city,the software development in HP workstation was completed.The experiment result shows that the accuracy rate of interest point speech recognition of the presented scheme reaches 97%,in which precisely match up to 171 times,23 times to obtain accurate results through multi-channel integration.It fully illustrated the effectiveness of this solution.
