Abstract

The invention discloses a Chinese speech control system and method with mutually interrelated spectrograms for a driver. The control system is composed of a special Chinese speech identification control device (1), a silicon microphone (2), an infrared CCD (Charge-Coupled Device) camera (3) and a vehicle-mounted electronic device (4). The special Chinese speech identification control device (1) is electrically connected with the silicon microphone (2), the infrared CCD (Charge-Coupled Device) camera (3) and the vehicle-mounted electronic device (4). The special Chinese speech identification control device (1) is composed of a DSP (Digital Signal Processor) chip (11), a video AD (Analog-to-Digital) module chip (12), a synchronous FIFO (First Input First Output) chip (13), a speech encoding / decoding chip (14), a CPLD (Complex Programmable Logic Device) chip (15), a 1# relay (16) and a 2# relay (17). The vehicle-mounted electronic device (4) comprises an air conditioner (4a) and a trunk lock (4b). The invention also provides a method for controlling the vehicle-mounted electronic device (4) by using the system.

Description

technical field [0001] The present invention relates to a driver-specific Chinese speech recognition control device and method applied to motor vehicles, more specifically, the present invention relates to a driver-specific Chinese speech recognition control system and method in a vehicle with spectrogram cross-correlation . Background technique [0002] With the popularization of automobiles in our country and the continuous progress of automobile technology, people's understanding and requirements for vehicles are no longer limited to simple means of transportation, but more focus on its comfort, safety and various convenient vehicles. Smart features. In-vehicle voice recognition and control technology is one of the important core technologies of smart cars. It can be applied to the car to realize intelligent operation. By recognizing the driver's pronunciation, voice commands can be used instead of manual voice control of some automotive electronic devices. The driver's...
