Problems solved by technology

On the one hand, this input method affects the safe driving of drivers; on the other hand, it is very inconvenient to input address entries using a soft keyboard on the touch screen. There are about tens of thousands of address names in the electronic map of a large and medium-sized city. It is very cumbersome and difficult to find a place name that users need in such a large database

Embodiment Construction

[0024] Please refer to figure 1 , which is a system structure block diagram of a preferred embodiment of the system of the present invention. Such as figure 1 As shown, the structural body of the entire voice-controlled vehicle GPS navigation system includes three parts: an electronic map module, a list of place names and a voice recognition module. First, the electronic map module generates a list of place names of cities as the recognition set of the speech recognition module, and the recognition result of the speech recognition module is sent to the electronic map module through data communication; if the speech recognition module gives multiple recognition candidates, then these candidate entries will all be displayed On the touch screen, after the user selects and confirms, the result is sent to the electronic map module. The electronic map module maps the obtained identification items into coordinate points of the map and displays them on the display screen. It can be...

Abstract

The invention relates to a voice-controlled vehicle GPS navigating system and the method for realizing the same, comprising the following steps of: 1, an electric map module make the place names in a map into a place name list, and the place name list is used as a distinguishing set for a voice distinguishing module and then is sent to the voice distinguishing module; 2, the start-up key of the voice distinguishing module is turned on; 3, the voice distinguishing module receives input voice and extracts characters of the input voice; 4, voice recognition is performed after abstracting the characters; 5, after the voice recognition is finished, a plurality of candidates are output for the final affirmation of users; 6, the final results affirmed by users are transmitted to the electric map module and then is mapped into corresponding map coordinate to be displayed on a screen. The invention not only simplified the operation procedures of GPS device, but also provides safeguards for drivers, and the invention, at the same time, facilitates the popularization of GPS.

Description

technical field [0001] The invention relates to a GPS navigation system, in particular to a voice-controlled vehicle-mounted GPS navigation system and a realization method thereof. Background technique [0002] The application of GPS has been very extensive, involving almost all fields of the national economy, especially in recent years with the development and prosperity of China's automobile consumer market, GPS positioning and GPS navigation have a strong momentum of development to the consumer market.
