The present application relates to the technical field of household appliances, and in particular, to a voice control method, a voice recognition module, a home appliance, a system, and a computer-readable storage medium.

Background technique

Home appliances such as air conditioners, electric fans, kitchenware, and refrigerators have become essential products for people. With the rapid development of artificial intelligence technology, home appliances with voice recognition have also emerged endlessly, greatly improving users. Experience.

In related technologies, the above-mentioned home appliances are usually provided with a voice recognition module and a control chip (such as MCU, CPU, DSP, single-chip microcomputer, and embedded devices), and the voice recognition module and the control chip are communicated through a communication interface (such as UART (Universal Asynchronous Receiver) / transmitter (asynchronous transceiver), SPI (Serial Peripheral Interface), Wi-Fi interface, Zigbee interface, mobile cellular interface, etc.) for control instruction interaction, the voice recognition module can control the executed control Instructions to broadcast, but the above voice control scheme at least the following

In addition, the voice recognition module may misidentify the same control instruction as multiple control instructions under noise interference, and After the instructions are executed, multiple repeated control instructions are broadcast to the user, which leads the user to mistakenly believe that the home appliance has malfunctioned, which seriously affects the user's experience.

Application content

This application is intended to solve at least one of the technical problems existing in the prior art or related technologies.

Therefore, an object of the present application is to provide a voice control method.

Another object of the present application is to provide a speech recognition module.

Another object of the present application is to provide a home appliance.

Another object of the present application is to provide a system.

Another object of the present application is to provide a computer-readable storage medium.

In order to achieve the above object, according to an embodiment of the first aspect of the present application, a voice control method is provided, including: broadcasting an executed first control instruction, and storing the first control instruction as a comparison instruction; in response to a user's Voice input information to generate a second control instruction to be broadcast; detect the time difference between the timestamp of the second control instruction and the timestamp of the comparison instruction; determine whether the second control instruction is required based on the magnitude relationship between the time difference and the preset time difference The control instruction and the comparison instruction perform data bit comparison to determine whether the second control instruction is broadcast.

In this technical solution, the executed first control instruction is broadcasted, and the first control instruction is stored as a comparison instruction. Since the misidentified repeated control instruction is usually generated in a short time, the time stamp of the control instruction is relatively If it is close, then when generating the second control instruction to be broadcast, first, by comparing the timestamp between the second control instruction and the comparison instruction, it is determined whether the second control instruction is a misidentified repeated control instruction. The timestamps between the second control instruction and the comparison instruction are very close, then it is necessary to further compare whether the data bits are the same, and then more accurately determine whether the second control instruction is a misidentified duplicate control instruction.

Wherein, the above-mentioned voice control method is implemented in a voice recognition module, and in order to reduce the power consumption of the voice recognition module, the voice recognition module usually belongs to a sleep mode, and converts the voice input information issued by the user into an instruction and determines that it includes a preset The voice recognition module only enters the wake-up mode when the control instruction is received, and forwards the control instruction to the hardware drive module (or control chip) of the home appliance. Each duration in the wake-up mode is greater than or equal to a preset time difference, preferably The preset time difference is set to 1 second to 5 seconds.

Preferably, a first storage area and a second storage area are respectively provided for storing a second control instruction and a comparison instruction to be broadcast, wherein the first storage area and the second storage area are preferably first-in-first-out storage space, The pointer moves gradually from the head to the tail of the queue. The control instruction pointed by the pointer is the object to be compared. After the comparison, the control instruction is cleared to release the buffer space.

Those skilled in the art can understand that when judging whether the second control instruction (first in the queue of the first storage area) is repeated, the comparison instruction is in the first queue of the second storage area, and so on, according to the second storage area The internal comparison instruction sequentially judges the second control instruction to be broadcast in the first storage area.

In addition, the preset time difference is an empirical value determined through a large amount of experimental data, that is, a misrecognition control instruction generated by the voice recognition module may only be generated within the above preset time difference. Therefore, when it is detected that the time difference exceeds the preset time difference, then It can be determined that the second control instruction is not a control instruction generated by misidentification.

It is worth pointing out that the cycle of each pointer movement in the second storage area is greater than or equal to the preset time difference, that is, the time that the pointer points to the first control instruction in the queue of the second storage area is greater than or equal to the preset time difference. In addition, When the second storage area is empty, it means that there is no comparison instruction that has been broadcast within the preset time difference. Waiting for the second control instruction at the top of the queue in the first storage area to finish executing, you can directly broadcast it.

In any of the above technical solutions, preferably, according to the magnitude relationship between the time difference and the preset time difference, it is determined whether a data bit comparison between the second control instruction and the comparison instruction is required, and then whether the second control instruction is broadcast, specifically Including: when detecting that the time difference is less than or equal to the preset time difference, comparing whether the data length bit of the second control instruction is the same as the data length bit of the comparison instruction; determining whether the data length bit of the second control instruction is the same as the data length of the comparison instruction When the bits are the same, compare whether the data indication bit carried by the second control instruction is the same as the data indication bit of the comparison instruction; when it is determined that the data indication bit carried by the second control instruction is the same as the data indication bit of the comparison instruction, it is determined not to broadcast the second control instruction.

In this technical solution, by detecting that the time difference is less than or equal to a preset time difference, if it can be further determined that the data length bit of the second control instruction is the same as the data length bit of the comparison instruction, and the data indication carried by the second control instruction is determined If the bit is the same as the data indication bit of the comparison instruction, it can be determined that the second control instruction is generated due to misrecognition by the voice recognition module or the user repeatedly inputs voice information. Therefore, as a misidentified repetitive instruction, it does not need to be executed or required. Voiced again.

The data length bit of the control instruction refers to the length of the data packet. In order to improve the detection efficiency and accuracy, it is preferred to first determine whether the data length bit of the comparison instruction is the same as the data length bit of the second control instruction. If the bits are different, it can be determined that the comparison command and the second control command are different voice input information. At this time, the second control command needs to be executed and the voice is broadcasted. If the data length is the same, then the two controls are further judged. Whether the data indication bits of the instructions are the same, to further improve the accuracy and reliability of the voice control scheme defined in the present application.

In any of the above technical solutions, preferably, according to the magnitude relationship between the time difference and the preset time difference, it is determined whether a data bit comparison between the second control instruction and the comparison instruction is required, and then whether the second control instruction is broadcast, specifically It also includes: when detecting that the time difference is less than or equal to a preset time difference, sequentially comparing whether each data bit of the second control instruction and the comparison instruction is the same according to the coding order of the control instruction; When each data bit is the same, it is determined not to broadcast the second control instruction.

In this technical solution, since the algorithm of generating the user's voice input information for the control instruction is the same, that is, the encoding structure of the comparison instruction and the second control instruction is the same, therefore, when the detected time difference is less than or equal to the preset time difference In this case, comparing each data bit of the second control instruction and the comparison instruction in sequence according to the encoding order of the control instruction can improve the accuracy and reliability of the comparison between the second control instruction and the comparison instruction to the greatest extent.

In addition, if the language broadcasting function can be turned on or off at any time as an independent process, and it does not interfere with the speech recognition function, then after the control instruction is executed, it is necessary to check whether the speech broadcasting function is turned on. Then determine whether to broadcast the second control instruction. After waiting for the second control instruction to finish broadcasting, copy it as a new comparison instruction to the second storage area. If the voice broadcast function is not enabled, the second control instruction is not broadcasted. It is not copied to the second storage area.

In any of the above technical solutions, preferably, determining whether to compare the second control instruction and the comparison instruction according to a magnitude relationship between the time difference and the preset time difference, and specifically includes: detecting that the time difference is less than or equal to the preset time difference. When determining whether the designated data bit of the second control instruction is the same as the designated data bit of the comparison instruction; when it is determined that the designated data bit of the second control instruction is not the same as the designated data bit of the comparison instruction, according to the execution of the second control instruction The result determines whether to broadcast.

In this technical solution, when generating the second control instruction to be broadcast according to the voice input information, in order to reduce data interaction conflicts, the data bits in the second control instruction include multiple redundant data bits and information data bits. Among them, the redundant data bits are used to indicate the communication rules, and the information data bits are used to indicate the data content of the control information. Even if the second control instruction is different from the comparison instruction, the redundant data bits may be the same. Therefore, By detecting whether the specified data bit of the second control instruction is the same as the specified data bit of the comparison instruction when it is detected that the time difference is less than or equal to the preset time difference, preferably, the specified data bit is the above-mentioned information data bit, and no redundancy is required. The comparison of the data bits can effectively improve the accuracy and reliability of judging whether the second control instruction is broadcast.

In any of the above technical solutions, preferably, when it is determined that the designated data bit of the second control instruction is different from the designated data bit of the comparison instruction, determining whether to broadcast according to the execution result of the second control instruction specifically includes: When the designated data bit of the second control instruction is different from the designated data bit of the comparison instruction, it is determined that the second control instruction is an instruction that needs to be broadcasted; when receiving feedback information that the second control instruction has been executed, at a preset time interval The second control instruction is broadcasted within.

In this technical solution, when it is determined that the designated data bit of the second control instruction is different from the designated data bit of the comparison instruction, it is not necessary to compare the redundant data bits, and the second control instruction can be determined to be an instruction that needs to be broadcast. At the same time, when receiving feedback information that the second control instruction has been executed, broadcasting the second control instruction within a preset time interval is beneficial to improving the reliability and accuracy of the voice broadcast.
