Referring to fig. 2, a first embodiment of a voice control method for a vehicle meter according to the present invention includes:
step S10, collecting voice information through a vehicle-mounted microphone, and monitoring whether the voice information contains keywords or not;
it is understood that, in the present embodiment, the implementation subject is a vehicle-mounted device with a voice recognition function, such as a car machine of an automobile, and for clarity, the car machine is used as the implementation subject for description. When a user is in a normally open state during the driving process, the microphone device of the vehicle-mounted device collects voice information sent by the user in real time, and therefore when the user tries to perform voice operation, the vehicle-mounted device can quickly respond to voice instructions. It can be understood that, in general, not every piece of voice information in the voice information generated by the user includes a voice instruction, and therefore, the car machine will screen the voice information collected by the microphone, and screen out the voice information with the keyword, for example: and when a certain treasure asks for opening the driving information, wherein the certain treasure is a keyword, and when the voice system of the vehicle machine recognizes the keyword, voice information continuous with the keyword is further extracted. The specific keywords can be freely set according to the application scene.
Step S20, if the voice message contains key words, extracting voice instructions from the voice message;
and when the car machine monitors that the voice information contains the keyword, extracting the voice instruction from the voice information.
Further, voice segments are extracted from the voice information containing the keywords, and the voice segments are recognized to generate voice instructions, wherein the voice segments contain the keywords. Specifically, when keyword triggers the car machine and carries out voice information collection and stops, trigger the car machine again and carry out the collection next time, if stop after to trigger the middle interval of collection again and exceed when predetermineeing the time, then judge that the car machine that triggers before the present moment carries out voice information collection record and gathers the voice information who gathers between the record stops and be the pronunciation fragment, if: the method includes that a user sends a piece of voice information to be 'a certain treasure please open driving information', and then continues to send voice information without keywords after a preset time interval is exceeded, a vehicle machine system recognizes the 'a treasure' keyword and starts to record the voice information and start timing, when the timing time does not reach the preset time, words 'please' are collected again, the timing time is reset to zero and is timed again, subsequent 'opening driving information' is collected in the same mode, and until the words 'the timing time is counted again after the words' are collected and the timing time exceeds the preset time, the 'a treasure please open driving information' received at the moment is taken as a voice fragment containing a voice instruction, so that the voice information without the voice instruction is separated, and it can be understood that all the voice fragments extracted from the voice information by the vehicle machine include the keywords.
Further, acquiring a first information quantity of the voice fragment and a second information quantity of the keyword; taking the ratio of the second information quantity to the first information quantity as a keyword weight value; judging whether the weight value of the keyword is larger than a preset weight threshold value or not; if the weight is larger than the preset weight threshold value, judging that the voice segment contains an effective voice instruction, and executing the step of recognizing the voice segment to generate the voice instruction.
It can be understood that, in this embodiment, the microphone is used for real-time acquisition, and besides the user realizes human-computer interaction through voice, a scene that the user communicates with other passengers may also exist, and voice information is also generated in the communication process, therefore, the microphone is used for acquiring the voice information that the user communicates with other passengers, if a keyword occurs in the communicated voice information, the car machine is used for carrying out misjudgment and extracting a voice segment from the voice information that the user communicates with other passengers, obviously, the extracted voice segment does not contain a voice instruction, and unnecessary voice feedback is sent to the user after the car machine does not find the voice instruction matched with the voice segment from the instruction library. After the voice segment is extracted, a first information amount of the voice segment is further obtained, where the first information amount of the voice segment is the number of words included in the voice segment, and similarly, a second information amount of the keyword is the number of words of the keyword, for example, the first information amount of the voice segment "a treasure opens the vehicle information" is 8, and the second information amount of the keyword "a treasure" is 2, so that a ratio of the second information amount to the first information amount is 0.25, that is, a weight value of the keyword is 0.25. It can be understood that, in an actual voice control scenario, when a user sends a voice instruction to an automobile, in a normal case, the information amount contained in the voice instruction is not too large, that is, the number of words of the voice instruction is not too large, and then the corresponding keyword weight value is not too small, so that the voice instruction with the largest information amount in the instruction library can be combined with the keyword to obtain the possible minimum keyword weight value, meanwhile, the user may add a custom phrase on the basis of the combination of the voice instruction with the largest information amount and the keyword when actually sending the instruction, so that the theoretical minimum keyword weight value is multiplied by a coefficient between 0 and 1 to obtain a preset weight threshold, which can be understood that the minimum keyword weight value and the coefficient can be obtained according to the actual instruction information amount and experience. If the preset weight threshold is 0.1, the voice segment 'a certain treasure opens the driving information' with the keyword weight value of 0.25 is judged as an effective voice segment by the car receiver, and the step of recognizing the voice segment to generate the voice instruction is continuously executed.
Further, after the step of determining whether the weight value of the keyword is greater than a preset weight threshold, if the weight value of the keyword is not greater than the preset weight threshold, it is determined that the voice segment does not contain a valid voice instruction, and the voice segment is discarded.
Specifically, based on the above example, the voice segment containing the keyword extracted from the communication information between the user and the passenger is usually large in information amount of the voice segment and small in weight value of the corresponding keyword, and by setting the keyword weight threshold, the voice segment smaller than or equal to the keyword weight threshold is regarded as an invalid voice segment and does not contain a voice instruction, and the invalid voice segment is discarded, so that unnecessary voice feedback to the user is avoided after the car machine does not find the voice instruction matching the voice segment from the instruction library.
And after the car machine extracts the voice segment, continuously recognizing the voice command from the voice segment. And matching fields in the voice fragment with basic instructions in a preset instruction library, for example, matching a driving information field in the voice fragment 'a certain treasure please open driving information' with an instruction 'driving information' in the instruction library, so that the voice instruction extracted from the voice fragment is 'driving information'.
In addition, the driving information further comprises: average fuel consumption/instantaneous fuel consumption/driving mileage/driving time/average vehicle speed/driving tire pressure, etc., so that each type of driving information also has corresponding voice instructions, such as: the voice instruction for checking the average oil consumption of the running vehicle is 'average oil consumption of the running vehicle', the instruction is matched with the 'running vehicle information required to be opened by a certain treasure' in a running vehicle field, in order to avoid instruction confusion, when the voice instruction is recognized from the voice segment, the voice instruction is recognized according to the matching degree of the voice segment and a basic instruction in a voice instruction library, and if two voice instructions 'running vehicle information' and 'average oil consumption of the running vehicle' which are also matched with the voice segment in a matching field are recognized, wherein the field of matching the 'running vehicle information' and the voice segment is the running vehicle information; the vehicle driving average oil consumption is a field vehicle driving matched with the voice fragment, and the matching field of the vehicle driving information is more than the vehicle driving average oil consumption, so that the matching degree of the vehicle driving information and the voice fragment is more than the vehicle driving average oil consumption, and when the vehicle-mounted device identifies the voice instruction in the voice fragment, the vehicle-mounted device preferentially identifies the vehicle driving information with high matching degree as the voice instruction contained in the voice fragment.
Step S30, judging whether the target object of the voice command is a vehicle combination meter;
after the car machine extracts the voice command from the voice segment, further determining a target object for executing the voice command, for example, in this embodiment, taking the target object as the vehicle combination meter as an example, the voice command is tagged with a tag corresponding to the target object, and if the target object is a related command of the vehicle combination meter, the tag includes: the driving information/driving average oil consumption/driving instantaneous oil consumption/driving endurance mileage/driving time/driving average vehicle speed/driving tire pressure and the like, wherein the instructions are marked with 1, so that when the instruction extracted by the vehicle machine is marked with 1, the target object of the instruction is judged to be the vehicle combination instrument.
And step S40, if the target object of the voice instruction is the vehicle combination instrument, sending the voice instruction to the vehicle combination instrument, and controlling the vehicle combination instrument to execute the voice instruction.
Further, the voice instruction is sent to the vehicle combination instrument through a Controller Area Network (CAN) Network of the vehicle. When the vehicle machine judges that the target object of the instruction is the vehicle combination instrument according to the extracted voice instruction, the voice instruction is sent to the vehicle combination instrument through the vehicle CAN network, the vehicle combination instrument is controlled through the voice instruction, for example, the voice instruction is driving information, and when the vehicle combination instrument receives the driving information, the driving information of the current vehicle is called to be displayed on an instrument display screen.
Further, if the voice instruction is to call driving information, the driving information fed back by the vehicle combination instrument according to the voice instruction is obtained; and displaying the running information through a vehicle display screen.
If the voice instruction is the operation of calling the running information, the vehicle combination instrument receives the instruction and then feeds the called running information of the current vehicle back to the vehicle machine besides calling the running information of the current vehicle to be displayed on the instrument display screen, and the vehicle machine receives the instruction and then displays the called running information through the vehicle machine display screen.
Further, judging whether the car machine is in an information voice broadcasting mode or not; and if the information voice broadcasting mode is opened, the driving information is subjected to voice broadcasting.
The car machine judges whether the car machine is in an information voice broadcasting mode or not, if the information voice broadcasting mode is opened (the car machine is opened under the default condition), the car machine carries out voice broadcasting on the received driving information, and the driving user is prevented from checking the corresponding display screen by distraction.
In this embodiment, the car-mounted system extracts the voice information of the user through the vehicle-mounted microphone, extracts the voice instruction, and determines whether a target object of the voice instruction is the car combination instrument, if so, the voice instruction is sent to the car combination instrument through the CAN network of the car, and after the car combination instrument receives the instruction, the voice instruction is executed. The data interaction between the vehicle machine and the vehicle combination instrument is realized through the CAN network, the effect of controlling the vehicle combination instrument through voice is achieved, and the problem that a user needs to operate the vehicle combination instrument manually if the user needs to operate the vehicle combination instrument during driving is solved. Thereby reducing the safety risk during driving. In addition, when the car machine extracts the voice instruction from the voice information, firstly, the keyword weight value of the extracted voice fragment is obtained, whether the voice fragment contains the effective voice instruction is judged, and after the voice fragment is determined, the voice instruction in the voice fragment is further identified according to the matching degree of the instruction field in the instruction library and the field in the fragment, so that the accuracy of car machine voice identification is improved.
