Problems solved by technology

In foreign countries, Robert Bosch has also developed a "method and device for voice control of appliances and systems in automobiles". The invention needs to detect one or more predetermined parameters of the current state of the car; Royal Philips Electronics Co., Ltd. "Method for controlling devices, especially devices in cars, by voice signals" requires the use of additional devices to detect noise inside the car as a reference; There is a voice control method that can achieve a better recognition success rate and reduce the false recognition rate through the preset vocabulary

Embodiment Construction

[0017] The automobile electric appliance voice control method that the present invention proposes, in conjunction with accompanying drawing, describe in detail as follows:

[0018] The inventive method, such as figure 1 shown, including the following steps:

[0019] 1) Generate a voice vocabulary for voice control of automotive electrical appliances;

[0020] 2) Generate a noise vocabulary for filtering out the noise signal in the car and the meaningless conversation of the driver, so as to reduce the false recognition rate and improve the system recognition success rate;

[0021] 3) The speech recognition engine (the speech recognition engine adopts common speech recognition engine products) records the voice of the driver;

[0022] 4) described speech vocabulary and noise vocabulary are merged; Load in a speech recognition engine after merging, select the word that pronunciation is the closest to the driver's speaking voice from described speech vocabulary;

[0023] 5) Ac...

Abstract

The invention relates to a vehicle electrical-apparatus sound control method based on a command-word table, which belongs to the technical field of vehicle electronic control. The method comprises the steps of generating a sound word table and a noise word table, making use of a sound identifying engine to record the sound of the driver, combining the sound word table with the noise word table, then loading the combined word table to the sound identifying engine and selecting the word with the pronunciation similar with the sound of the driver from the sound word table, identifying the speech intention of the driver according to the word output by the sound identifying engine, and the identified result is the determined electrical-apparatus control command, converting the electrical-apparatus control command into a CAN bus control signal and outputting the control signal to the CAN bus to control the electrical-apparatus. Due to the use of the control method of the invention, during the vehicle-running process, the controlling performance for the noise is stronger, the error operation is reduced considerably, and the identification precision is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic control, and in particular relates to a voice control method of automobile electrical appliances. Background technique [0002] Voice interaction is a means of using language to interact between people and machines. Voice interaction is a means of human-computer interaction. Compared with traditional human-computer interaction, voice interaction has the ability to move simultaneously with hands and eyes, and quickly and directly obtain / input information. specialty. The use of voice control technology in cars is just getting off the ground, but growing fast. For example: voice-activated car phone, voice-activated radio channel selection and DV song selection, voice navigation, anti-theft voice identification and so on. [0003] More and more electrical appliances are used in modern cars, and there are more and more switches in the cab, which increases the burden on the driver and af...
