Abstract:
1. A voice-controlled navigation method, the method being performed by execution of computer readable program code by at least one processor of an electronic device, and comprising: (a) receiving a voice command of a destination which comprises place names, and dividing the voice command into voice segments Vi (i=1˜n) by comparing the voice command with one or more keywords by the at least one processor; (b) obtaining a voice segment Vi (i=1˜n), comparing the voice segment Vi with tree nodes of a search tree, wherein the tree nodes of the search tree represent place names, computing a weight value of each tree node according to a comparison between the voice segment Vi and each tree node, and selecting one or more tree nodes whose weight values are greater than a predetermined value by the at least one processor; (c) obtaining routes formed by all the selected tree nodes of the search tree, and selecting a route whose total weight value is the greatest by the at least one processor; and (d) giving a navigation to the destination by indicating the selected route on an electronic map according to place names represented by the tree nodes of the selected route by the at least one processor.
