Abstract

The invention discloses a speech control vehicle-mounted navigation system which comprises a central processing unit, a data bus receiving and dispatching module, a GPS (global position system) module, a speech input module, an A/D conversion module, a signal preprocessing module, a characteristic vector extracting module, a speech recognition module and an I2C controller, wherein the GPS module receives a GPS signal to generate position information and has data communication with the central processing unit through the data bus receiving and dispatching module; the speech signal received by the speech input module is converted into a digital signal via the A/D conversion module and stored through the signal preprocessing module; the characteristic vector extracting module selects characteristic vector parameters from short-time speech frame, delivers the characteristic vector parameters to the speech recognition module for judgment, and outputs the recognition result to the I2C controller, so that the speech control of the vehicle-mounted navigation system by a driver is realized, driving is not affected while the navigation operation is performed, more time of the driver is saved, and convenience and practicality are realized.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a voice-controlled vehicle navigation system. Background technique [0002] In recent years, the domestic car navigation industry has developed rapidly, the penetration rate has been greatly improved, and the technology and functions have become more and more perfect. When the current car navigation is in operation, the driver operates through the buttons. Generally, the driver first starts the machine, then finds the road category, and then enters the destination to search. When performing the destination search, the driver enters the place name of the destination on the touch screen. , to finalize. However, in this mode of operation, the driver will spend a lot of time to operate, and at the same time, it cannot be operated while driving. It is very dangerous to perform manual operation while driving, so it brings inconvenience to the driver. Contents of the inven...
