Users can easily control various electronic devices in their homes with just a simple voice command, and this unprecedented convenience undoubtedly brings great comfort and enjoyment to our lives.
[0003] However, with the increasing variety of smart home products, the number of command words users need to remember and use is also rising sharply. This is not just a simple matter of numerical growth, but a significant challenge concerning user experience and efficiency. In emergency or specific situations, such as needing to leave the house quickly but not being able to find the command words to control the door lock with their phone, or needing to adjust the bedroom lights at night but forgetting the corresponding voice commands, users often feel frustrated because they cannot remember or confuse the command words of different products. This frustration not only reduces the user experience of smart home products, but may also weaken users' trust and reliance on smart home technology to some extent.

[0052] This application provides a voice control method to efficiently and accurately provide command prompts when a user issues an incorrect command, thereby improving the efficiency of completing the target command corresponding to the user's actual needs and enhancing the user experience. The method provided in this application involves acquiring first voice data from the target user while the voice control program is in an active state, determining a first target command from the first voice data, and, if the first target command is an incorrect command, providing command prompts based on a preset command set and a commonly used command set. It also involves acquiring second voice data from the target user, determining a second target command from the second voice data, and executing the second target command to complete the voice control. This achieves efficient and accurate command prompts even when the user issues an incorrect command, improving the efficiency of completing the target command corresponding to the user's actual needs and enhancing the user experience.
[0053] The voice control method provided in this application can be applied to terminal devices for home control, such as mobile phones, tablets, wearable devices, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), and other computer devices. This application does not impose any restrictions on the specific type of terminal device.
[0054] like Figure 1 As shown, a first aspect of this application provides a voice control method, including:
[0055] Step S10: With the voice control program in a wake-up state, acquire the first voice data of the target user.
[0056] In the application, the voice control program is in sleep mode by default to maintain low power consumption and save battery and computing resources. After the user triggers a preset wake-up condition, the voice control program switches from sleep to wake-up mode. In wake-up mode, it can access various components, acquire and process the user's voice data. The preset wake-up condition can be detecting a preset wake-up word at a preset frequency or detecting a wake-up signal, such as detecting two wake-up words within two seconds, or detecting a wake-up signal generated by a physical hardware button being triggered (e.g., electrical signal, Bluetooth signal, infrared signal, etc.). Understandably, to reduce the chance of false wake-ups, the wake-up word can be set to a word that appears less frequently in daily life.
[0057] In the application, the user will wake up the voice control program when they need to perform voice control. Therefore, while the voice control program is in an awakened state, the microphone is continuously used to acquire the user's initial voice data, which contains the user's request to wake up the voice control program.
[0058] Step S20: Determine the first target command from the first voice data.
[0059] In the application, the first speech data acquired through microphone data undergoes preprocessing operations such as noise reduction, echo cancellation, and background noise removal. Then, speech recognition is performed on the preprocessed speech data to obtain the first target text data. Finally, word segmentation and syntactic analysis are performed on the first target text data to extract the first target command conforming to a preset command format.
[0060] Step S30: If the first target command is an incorrect command, provide command prompts based on a preset command set and a commonly used command set.
[0061] In the application, the system searches for a first target command within a preset command set. It then determines if the same preset command exists in the set, or if a preset command with a similarity greater than a preset similarity threshold exists. If none exists, the first target command is considered an incorrect command. If the first target command is an incorrect command, command prompts are provided based on the preset command set and commonly used command set, either played through the speaker or displayed on the screen.
[0062] In applications, the primary target command can be expanded using methods such as synonyms, abbreviations, or expanded terms to increase the tolerance for user commands.
[0063] Step S40: Obtain the second voice data of the target user.
[0064] In applications, taking command prompts played through a speaker as an example, the user's second voice data can be acquired after the command prompt ends. This avoids interference from the speaker's sound on the acquisition of second voice data from multiple users, ensuring the accuracy and reliability of the second voice data acquisition. However, since user behavior is uncontrollable—for example, the user might attempt to perform voice control again before the command prompt ends—the command prompt can be paused, and the user's third voice data can be received. If the third voice data is a preset command, it is executed; if the third voice data is an incorrect command, then, depending on the user's choice, command prompts can continue based on the first voice data or a new command prompt can be generated by combining the first voice data.
[0065] Step S50: Determine the second target command from the second voice data and execute the second target command to complete voice control.
[0066] In the application, after the command prompt ends, the second voice data issued by the user based on the command prompt is obtained, and the second target command is determined from the second voice data. Under the command prompt, the second target command is a preset command in the preset command set. The voice control is completed by executing the second target command to meet the user's voice control needs.
[0067] like Figure 2 As shown, in one embodiment, the command prompting based on a preset command set and a commonly used command set includes:
[0068] Step S301: Determine the number of preset commands in the preset command set.
[0069] In applications, the number of preset command sets varies considerably due to limitations in the hardware performance and intended use of the terminal devices.
[0070] Step S302: If the number of preset commands is less than the first preset threshold, then obtain the commonly used commands from the commonly used command set.
[0071] In application, the first preset threshold can be set according to the actual situation, for example, it can be set to 17. If the number of preset commands is less than the first preset threshold, it means that the number of commands in the preset command set is small and the distribution of commonly used commands is relatively concentrated. Command prompts can be given based on the commonly used command set.
[0072] In the application, the number of times each preset command is executed is counted, and commands that are executed in the top preset percentage within a preset time period are marked as frequently used commands. For example, preset commands that are executed in the top preset 50% of the time over a month or a quarter are marked as frequently used commands.
[0073] Step S303: Provide command prompts based on the usage frequency of each commonly used command.
[0074] In the application, command prompts can be given based on the frequency of use of frequently used commands. For example, the top five most frequently used commands can be announced, or all frequently used commands in the frequently used command set can be announced in descending order of frequency.
[0075] like Figure 2 As shown, in one embodiment, the command prompting based on a preset command set and a commonly used command set further includes:
[0076] Step S304: If the number of preset commands is not less than the first preset threshold, then extract the command keywords from the first voice data.
[0077] In applications, if the number of preset commands is not less than a first preset threshold, it means that there are many preset commands in the preset naming set, and the proportion of frequently used commands is relatively low. Using only frequently used commands for command prompts is inefficient and ineffective. In this case, by extracting keywords from the first voice data and matching corresponding commands in the preset command set based on these keywords, the efficiency and accuracy of command prompts can be improved.
[0078] Step S305: Based on the command keyword, match it in the preset command set to obtain the keyword command.
[0079] In application, keyword commands can be obtained by directly matching within a preset command set based on command keywords; alternatively, command keywords can be expanded, and keyword commands can be obtained by matching within the preset command set based on the expanded command keywords.
[0080] Step S306: Provide command prompts based on the keyword commands.
[0081] In applications, the keyword commands obtained based on command keywords may be one or more, such as several or even a dozen. When the number of keyword commands is large and exceeds the preset keyword threshold, only the top five most frequently used keyword commands or the top 30% of keyword commands can be broadcast.
[0082] In one embodiment, step S10, before acquiring the first voice data of the target user while the voice control program is in a wake-up state, further includes:
[0083] Step S11: When the voice control program is in the wake-up state, if the voices of multiple users are detected, the user with the highest priority is identified as the target user.
[0084] In applications, after the voice program is activated, there may be scenarios where multiple users simultaneously speak. For example, a parent might want to turn off the TV via voice control, while a child simultaneously speaks, wanting to switch TV channels via voice control; or a homeowner might want to control the living room air conditioner via voice control, while guests are conversing in the living room. To ensure the accuracy of voice control in these situations, it's necessary to determine the user with the highest priority among the multiple users as the target user. Specifically, when multiple users are detected speaking, their identities can be identified through their voice timbre, tone, etc. Different user identities have different priorities; for example, the homeowner has a higher priority than guests, and adults have a higher priority than children. Based on the user's voice, their identity is determined, and according to the priority corresponding to that identity, the user with the highest priority is selected as the target user.
[0085] In one embodiment, step S50, determining a second target command from the second voice data and executing the second target command to complete voice control, includes:
[0086] Step S501: Determine the level restriction of the second target command. If the level restriction of the second target command is not higher than the priority of the target user, then execute the second target command to complete voice control.
[0087] In home applications, some appliances may pose a danger, such as heating devices. These devices could tip over or cause injury if operated at close range for extended periods, and therefore should be kept away from children. Therefore, by setting priority levels for preset commands, the system determines whether the user's priority is higher than the priority level of the target command before execution. The target command is only executed if the user's priority is higher than the priority level, thus improving the safety of voice control.
[0088] Step S502: If the level of the second target command is higher than the priority of the target user, then the execution of the second target command is refused and a level alarm is issued.
[0089] In the application, if the level of the second target command is higher than the priority of the target user, the second target command will be refused to be executed, and a level alarm will be issued to provide a certain reminder.
[0090] In the application, after an alarm is triggered, the user can remove the restriction on one command execution by issuing an unlock command. If the user-issued unlock command is detected after the alarm is triggered, the second target command is executed directly, ignoring the level restriction of the second target command.
[0091] In one embodiment, the method further includes:
[0092] Step S31: With the voice control program in the wake-up state, obtain the connection status and scene data of home devices.
[0093] In the application, the connection status of home devices includes online and offline. "Connected" indicates that the home device is normally connected, while "offline" indicates that the home device cannot connect, such as due to a power outage. Scene data includes information such as time, temperature, and humidity.
[0094] Step S32: Provide command prompts based on the connection status of the home devices, the scene data, the preset command set, and the commonly used command set.
[0095] Based on the connectivity status of home devices, for offline devices, command prompts for preset commands can be canceled, and an offline notification can be provided. For online devices, command prompts are provided based on scene data, preset command sets, and frequently used command sets. Specifically, the current scene is determined based on scene data, and commands relevant to the current scene are selected from the preset command set or frequently used command set and assigned greater scene weight. Command prompts are then based on the scene weight of each command. For example, commands related to turning on lights are given a higher scene weight within half an hour before and after sunset; commands related to turning off lights are given a higher scene weight between 10 and 11 pm, allowing for biased selection of different commands from the preset command set and frequently used command set for different scenes.
[0096] In one embodiment, the method further includes:
[0097] Step S33: If the first voice data includes prompt trigger data, determine that the user has forgotten the preset command; the prompt trigger data is the voice data in the first voice data that is repeated a first preset number of times within a first preset time period.
[0098] Step S34: If the user forgets the preset command, then provide command prompts based on the preset command set and the commonly used command set.
[0099] In applications, in addition to the home control terminal device providing command prompts after the user issues an incorrect command, the user can also directly trigger command prompts when they confirm that they have forgotten the target command, so as to trigger command prompts as quickly as possible and save time.
[0100] In the application, the prompt trigger data can be a wake word or a word other than a wake word, which can be configured by the user. Taking a wake word as an example, if it is detected that the user repeats the wake word a first preset number of times within a first preset time, such as saying the wake word three times in a row within two seconds, it is confirmed that the user has forgotten the preset command. Based on the preset command set and the frequently used command set, command prompts are given, directly broadcasting frequently used commands from the frequently used command set or preset commands from the preset command set that meet a certain frequency.
[0101] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
[0102] This application also provides a voice control system for executing the steps described in the voice control method embodiments above. The voice control system can be a virtual appliance in a terminal device, run by the terminal device's processor, or it can be the terminal device itself.

[0109] Determine the number of preset commands in the preset command set;
[0110] If the number of preset commands is less than the first preset threshold, then obtain the commonly used commands from the commonly used command set;
[0111] Command prompts are provided based on the frequency of use of each of the commonly used commands.
[0112] In one embodiment, the command prompt module 303 is used for:
[0113] If the number of preset commands is not less than the first preset threshold, then extract the command keywords from the first voice data;
[0114] Based on the command keywords, a matching process is performed in the preset command set to obtain the keyword commands;
[0115] Command prompts will be provided based on the aforementioned keyword commands.
[0116] In one embodiment, the voice control system 3 further includes:
[0117] The target user selection module 305 is used to identify the user with the highest priority as the target user if multiple users' voices are detected when the voice control program is in the wake-up state.
[0118] In one embodiment, the second command confirmation module 304 is used for:
[0119] Determine the level limit of the second target command. If the level limit of the second target command is not higher than the priority of the target user, then execute the second target command to complete the voice control.
[0120] If the priority of the second target command is higher than that of the target user, the second target command will be refused to be executed and a level warning will be issued.
[0121] In one embodiment, the command prompt module 303 is further configured to:
[0122] If the first voice data includes prompt trigger data, it is determined that the user has forgotten the preset command; the prompt trigger data is the voice data in the first voice data that is repeated a first preset number of times within a first preset time period;
