Example Embodiment

[0020] Examples:

[0021] A car audio voice control system of this embodiment, refer to figure 1 : Including hardware system and software module. The hardware system is composed of directional pickup, voice recognition module, control module and sound module. The pickup collects the voice commands issued by the driver, and uses the voice recognition module to convert the voice physical sound signal output by the pickup into voice digital Signal, and recognize the Chinese characters or words corresponding to the voice command, the control module generates the corresponding entry code instruction, and transmits the control command to the audio through the system I / O port line, and the car audio receives the control instruction to produce adjustment control actions. In response to the driver's voice commands, such as fast forward, fast rewind or volume adjustment, the software module includes a person-independent voice recognition module and a logic control module.

Abstract

The invention relates to the technical field of vehicle audios and videos, and provides a vehicle-mounted audio equipment speech control system. The system comprises a hardware system and a software module, wherein the hardware system is composed of a directional pickup, a speech recognition module, a control module and an audio module; the pickup collects a speech command emitted by a driver; thespeech recognition module is used for converting a physical speech signal output by the pickup into a digital speech signal, and recognizing Chinese characters or words corresponding to the speech command; and the control module generates a corresponding entry encoding command, and transmits the control command to audio equipment via a system I/O port line. According to the vehicle-mounted audioequipment speech control system, an SDA80D51 chip is used, so that speech recognition and control of speaker-independent of the vehicle-mounted audio equipment are achieved. The chip is high in integration level, so that fewer peripheral modules are needed, the designed hardware circuit is simple, and the system is convenient to debug and detect.

Description

technical field [0001] The invention relates to the technical field of car audio and video, in particular to a car audio voice control system. Background technique [0002] With the continuous application of modern electronic technology in automotive systems, more and more on-board electrical appliances have been added to the ranks of body electronics, which has greatly improved the various performances of the car, but the switches in the car cab are also becoming more and more The more, this puts forward higher requirements for the driver's operation of the on-board electrical appliances during driving, and also brings unsafe hidden dangers to the driving process. With the improvement of voice recognition algorithm and the advent of a new generation of SoC dedicated voice processing chips, the use of voice commands to control the operation of automotive electrical appliances can partially replace the functions of hands with the mouth, thereby reducing the driver's operating...
