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
The invention belongs to the auto electronic control technology field, particularly a kind of sound control method of car electrics.
Background technology
Interactive voice is to use language to allow people and machine carry out interactive means, and interactive voice is compared with traditional man-machine interaction as a kind of man-machine interaction means, and interactive voice has can be with the action simultaneously of hand, eye, directly obtain fast/characteristics of input information.The application of voice control technology on automobile is at the early-stage, but development is very fast.Such as: acoustic control car phone, acoustic control broadcasting channel selection and DV select song, Voice Navigation, antitheft voice to differentiate or the like.
The electrical equipment that modern automobile uses is more and more, and the switch of operator's compartment is also just more and more, and it has increased the burden of chaufeur, influences traffic safety.The control that utilizes speech recognition technology to carry out car electrics can alleviate the chaufeur burden partly with mouthful function of replacement hand.And along with increasing of vehicle-mounted microcomputer, multi-mode operation will become a kind of trend of vehicle drive mode.Abroad, Robert Bosch company has also developed " being used for the utensil and the system of automobile are carried out voice control method and device ", this invention is primarily aimed at vehicle-borne information equipment such as radio receiver, automobile telephone equipment, navigational aid etc., and should invention need to detect one or more automobile current state predetermined parameters; Royal Philips Electronics Co., Ltd's " by method of the equipment in the voice signal control convenience especially automobile " needs to adopt extra equipment to detect internal car noise as a reference; Also do not have at present by default vocabulary and can reach recognition success rate preferably and and reduce the sound control method of false recognition rate.
Summary of the invention
The objective of the invention is to propose a kind of sound control method, so that chaufeur can be with using the voice command that limits that the electrical equipment of automobile is controlled exactly to car electrics.Compare with general sound control method, use control method of the present invention, under the vehicle drive environment, noise is had stronger inhibition ability, significantly reduced faulty operation, improved accuracy of identification.
A kind of sound control method that carries out that the present invention proposes to car electrics, this method may further comprise the steps:
1) generates a voice vocabulary that is used for vehicle electrical apparatus sound control;
2) generate the noise vocabulary that a sound that is used for the meaningless talk of internal car noise signal and chaufeur carries out filtering, be used to reduce false recognition rate and improve the system identification success ratio;
3) sound of speaking of speech recognition engine (speech recognition engine adopts normal speech recognition engine product) record chaufeur;
4) described voice vocabulary and noise vocabulary are merged; Be loaded into after the merging in the speech recognition engine, select the most close word of sound of speaking of pronunciation and chaufeur from described voice vocabulary;
5) according to the word of speech recognition engine output, the intention of speaking of chaufeur is discerned the electrical equipment control order of the result of identification for determining;
6) the electrical equipment control command conversion that step 5) is obtained becomes the CAN bus control signal, outputs on the CAN bus, in order to electrical equipment is controlled.
Characteristics of the present invention and beneficial effect:
This method mainly is on the common vehicle-mounted microcomputer of a band microphone, add method proposed by the invention, and utilize common speech recognition engine, and load the voice command control vocabulary that the present invention proposes, by a kind of the driver-commanded method identification of driver that mates is intended to.When loading the voice command vocabulary, load the noise vocabulary, reduce the false judgment probability, improve success ratio to driver intention identification.
Compare with existing phonetic controller, the characteristics of this method are at vehicle mounted electrical apparatus design-calculated voice control command vocabulary, this vocabulary has adopted the phrase composing method of operational motion+electrical equipment noun, comprised the cooresponding operational order of nearly all vehicle mounted electrical apparatus and electrical equipment, adopt the method for noise vocabulary by the normal speech recognition engine operational order vocabulary that identifies to be identified as the driver's operation intention by the mode of mating then, this intention can send in the mode of CAN bus code on vehicle-mounted CAN/LIN bus, to reach the purpose of control.
The advantage of this method is under the vehicle drive environment, can overcome the interference that various noises bring, and having has high recognition and less false recognition rate to driver intention,
Description of drawings
Fig. 1 is the FB(flow block) of this method
The specific embodiment
The vehicle electrical apparatus sound control method that the present invention proposes is described with reference to the accompanying drawings as follows:
The inventive method as shown in Figure 1, may further comprise the steps:
1) generates a voice vocabulary that is used for vehicle electrical apparatus sound control;
2) generate the noise vocabulary that a sound that is used for the meaningless talk of internal car noise signal and chaufeur carries out filtering, be used to reduce false recognition rate and improve the system identification success ratio;
3) sound of speaking of speech recognition engine (speech recognition engine adopts normal speech recognition engine product) record chaufeur;
4) described voice vocabulary and noise vocabulary are merged; Be loaded into after the merging in the speech recognition engine, select the most close word of sound of speaking of pronunciation and chaufeur from described voice vocabulary;
5) according to the word of speech recognition engine output, the intention of speaking of chaufeur is discerned the electrical equipment control order of the result of identification for determining;
6) the electrical equipment control command conversion that step 5) is obtained becomes the CAN bus control signal, outputs on the CAN bus, in order to electrical equipment is controlled;
Generating the voice vocabulary in the described step 1) is that various operation verb and the vehicle mounted electrical apparatus nouns to vehicle mounted electrical apparatus that will collect constitute the voice vocabulary that verb adds noun, comprises also in this vocabulary that the synonym by the synonym of operating verb and electrical equipment noun carries out the voice vocabulary of combined crosswise;
