[0048] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0049] With the rapid development of natural language processing technology, voice interaction technology is becoming increasingly mature. Voice assistants are now widely used in various IoT devices such as mobile phones, TVs, and computers, covering various fields including movies, weather inquiries, device control, shopping, and consumption. However, the areas involved in voice interaction are diverse. For example, in smart refrigerators, voice commands can be used to intelligently control the refrigerator. Smart refrigerators are frequently used in daily life to store food. However, due to individual preferences and different tastes, sometimes smart refrigerators may store foods that users do not like. Current smart refrigerator technology does not provide a function to prompt for food replacement. This results in the storage of unwanted food in the smart refrigerator, affecting user experience.

[0050] To address the problems of existing technologies, this embodiment provides a food replacement prompt method based on voice commands. Specifically, this embodiment first acquires food replacement request information generated based on voice commands, indicating that the user needs to replace one type of food with another. Once the desired replacement food is identified, the invention can determine the corresponding food replacement operation instruction based on the food replacement request information. Finally, according to the food replacement operation instruction, the operation corresponding to the instruction is executed, and a food replacement prompt is output. This invention can prompt for food replacement based on food replacement request information generated based on user voice commands, facilitating timely food replacement for users and providing a user-friendly service.

[0051] For example, when the voice command-based food replacement prompt method in this embodiment is applied to a smart refrigerator, when a user wants to replace the pork in the refrigerator, they will issue a voice command, such as "replace the pork in the refrigerator with lamb." The smart refrigerator can acquire the user's voice command and then generate food replacement request information based on it. This request information indicates that the user wants to replace the pork with lamb. Therefore, the smart refrigerator can determine the corresponding food replacement operation command based on the request information, execute the corresponding operation, and output food replacement prompt information to facilitate the user's food replacement.

[0052] Exemplary methods

[0053] The voice-command-based food replacement prompt method of this embodiment can be applied to terminal devices, such as smart refrigerators. In specific implementation, for example... Figure 1 As shown, the food replacement prompt method based on voice commands in this embodiment includes the following steps:

[0054] Step S100: Obtain food replacement request information generated based on voice commands.

[0055] In this embodiment, when the voice command-based food replacement prompt method is applied to a terminal device, such as a smart refrigerator, when a user wants to replace food, they will issue a voice command to the smart terminal. This voice command is the user's spoken voice information. After receiving the voice command, the smart terminal will generate a food replacement request information based on the voice command. This food replacement request information reflects what food the user wants to replace and what the target food is. For example, if a user doesn't like pork, they will issue a voice command to the smart refrigerator to "replace the pork in the refrigerator." After receiving the voice command "replace the pork in the refrigerator," the smart refrigerator will generate the food replacement request information that the user wants to replace.

[0056] In one implementation, such as Figure 2 As shown, step S100 specifically includes the following steps:

[0057] Step S101: Real-time acquisition of the voice commands within a preset range;

[0058] Step S102: Obtain the sound characteristics in the voice command, the sound characteristics including: voiceprint features, loudness identifier, timbre identifier and pitch identifier;

[0059] Step S103: Determine the food replacement request information based on the sound characteristics.

[0060] In specific implementation, this embodiment collects voice commands within a preset range in real time. These voice commands are voice information issued by the user. For example, the smart refrigerator can collect voice commands within a 5-meter range. After collecting the voice command, this embodiment can begin to acquire the sound characteristics of the voice command. These sound characteristics are used to reflect the voiceprint features, loudness indicators, and timbre indicators in the voice command. These sound characteristics are used to analyze the voice command and determine whether the voice command was issued by a preset user. To facilitate user use, this embodiment first sets a corresponding preset user for each terminal device. This preset user is used to trigger the corresponding terminal device. For example, if the preset user corresponding to the smart refrigerator is A, then only voice commands issued by user A can be recognized and responded to by the smart refrigerator. That is, only user A can control the smart refrigerator through voice commands. Therefore, this embodiment can analyze the voiceprint features, loudness indicators, and timbre indicators in the voice command after collecting it. In this embodiment, the voiceprint feature is used to analyze the matching degree between the voiceprint in the received voice command and the voiceprint of a preset user. If the matching degree is higher than 80%, it indicates that the received voice command is indeed issued by the preset user. Similarly, the loudness identifier is used to analyze whether the loudness of the received voice command matches the loudness of the voice issued by the preset user. If they match, it indicates that the loudness of the received voice command is the same as that of the voice command issued by the preset user. Likewise, the timbre identifier and pitch identifier in this embodiment are used to analyze the matching degree between the timbre and pitch of the received voice command and the timbre and pitch of the preset user. If the matching degree is higher than 80%, it indicates that the received voice command is indeed issued by the preset user. After analyzing the voice command using these sound characteristics, it can be determined whether the received sound characteristics are those of a voice command issued by the preset user. If so, the food replacement operation request information generated based on the voice command can be obtained. For example, when a user tells the refrigerator to "replace the pork in the refrigerator," the smart refrigerator will obtain the voice characteristics of the user's voice command and then match those voice characteristics with a preset user. If the match is successful, it can be determined that the voice command "replace the pork in the refrigerator" was issued by the preset user. Therefore, it can generate a food replacement request based on the voice command "replace the pork in the refrigerator" and request the smart refrigerator to replace the food.

[0061] Step S200: Based on the food replacement request information, determine the food replacement operation instruction corresponding to the food replacement request information.

[0062] In specific implementation, after receiving the food replacement request information, this embodiment analyzes the food replacement request information to determine the food replacement operation instruction corresponding to the food replacement request information. For example, the smart terminal in this embodiment can also be equipped with a recording function. When the user outputs the voice information "replace the pork in the refrigerator," the smart terminal can use the recording function to receive the voice information "replace the pork in the refrigerator," which is the voice instruction. After receiving the voice instruction "replace the pork in the refrigerator," the smart terminal can generate the corresponding food replacement request information, which includes the voice instruction "replace the pork in the refrigerator." Therefore, when determining the voice information based on the food replacement request information, the smart terminal in this embodiment only needs to parse the food replacement request information to obtain the food replacement operation instruction corresponding to the food replacement request information as "replace the pork in the refrigerator."

[0063] In one implementation, such as Figure 3 As shown, step S200 specifically includes the following steps:

[0064] Step S201: Parse the food replacement request information to obtain the food replacement voice information corresponding to the voice command in the food replacement request information;

[0065] Step S202: Convert the food replacement voice information into text information, and determine the food replacement operation instruction corresponding to the food replacement request information based on the text information.

[0066] To determine the food replacement operation instruction corresponding to the food replacement request information in this embodiment, this embodiment can parse the food replacement request information after obtaining it to obtain the voice information corresponding to the voice instruction; convert the voice information into text information, and determine the food replacement operation instruction corresponding to the voice operation request instruction based on the text information. In one implementation, this embodiment can convert voice information into text information using speech recognition or speech translation. After obtaining the text information, this embodiment can parse the text information and then determine the field information, which consists of words or phrases in the text information. Since the text information is a sentence or some words recognized through voice information, and some words are meaningless, for example, when the recognized text information is "replace the pork in the refrigerator," only the fields "replace" and "pork" are relevant to the execution of the voice instruction. Because as long as these two fields are obtained, the smart terminal can determine the user's intent. The words "please" and "in the refrigerator" are meaningless in the execution of the voice instruction. As can be seen, in this embodiment, when determining field information based on text information, it is necessary to filter out some useless or meaningless fields in the text information in order to more accurately determine the user's intent.

[0067] Once the field information is determined, this embodiment can determine the food replacement operation instruction corresponding to the field information. In this embodiment, the field information is obtained from the text information, which in turn is obtained from the voice information corresponding to the voice instruction. Therefore, the field information can reflect the user's intent. For example, if the field information determined in the above example is "replace" and "pork," then the corresponding user intent is that the pork in the smart refrigerator needs to be replaced. The user intent reflects the type of operation event. In one implementation, this embodiment can pre-set a mapping file, which sets the correspondence between field information and food replacement operation instructions. Therefore, once the field information is obtained, it can be matched with the mapping file to match the corresponding food replacement operation instruction. For example, as in the example above, the determined field information is "replace" and "pork". In this embodiment, based on the field information "replace", the food replacement operation instruction matching "replace" can be determined as "food replacement prompt event". Furthermore, based on the field information "pork", it can be determined that "pork" matches "meat food". Then, by combining the determined food replacement prompt event with meat food, the final food replacement operation instruction can be determined as: prompt to replace the pork in the refrigerator.

[0068] Furthermore, to meet more application scenarios, this embodiment can also rewrite the field information, that is, customize the field information, thus allowing for the customization of food replacement operation instructions. In specific implementation, when rewriting the field information, this embodiment can rewrite the field information obtained from the voice information into specified field information, i.e., the intent information desired by the user. For example, in the example above, the field information obtained from the voice information is "dislike" and "onion." This embodiment can perform forced rewriting based on the determined field information. Forced rewriting means directly changing the field information to a specified field, then determining the specified operation instruction based on the specified field information, and using this specified operation instruction as the food replacement operation instruction. For example, this embodiment can rewrite the field information "dislike" and "onion" obtained from the voice information into the specified field information - "replace" and "onion." This allows for the direct generation of the corresponding specified operation instruction based on the specified field information, which is the food replacement operation instruction, i.e., replacing the onion in the refrigerator.

[0069] Step S300: According to the food replacement operation instruction, perform the operation corresponding to the food replacement operation instruction and output the food replacement prompt information.

[0070] Once the food replacement instruction is determined, this embodiment can execute the operation corresponding to the instruction. Furthermore, this embodiment also outputs a food replacement prompt to remind the user to replace the food promptly. The food replacement prompt in this embodiment can be delivered to the user via voice announcement or text display.

[0071] In one implementation, such as Figure 4 As shown, step S300 specifically includes the following steps:

[0072] Step S301: Obtain image information of the food storage space according to the food replacement operation instruction;

[0073] Step S302: Based on the image information, determine the food already stored in the food storage space;

[0074] Step S303: Based on the stored food, determine the food to be replaced and output a food replacement prompt message.

[0075] In specific implementation, after determining the food replacement operation command, this embodiment starts the camera installed on the terminal device to collect image information from the storage space. For example, when the terminal device is a smart refrigerator, the smart refrigerator is equipped with multiple hemispherical cameras, which collect image information from all directions of the storage space inside the smart refrigerator. During image collection, this embodiment takes pictures of all the food in the smart refrigerator from all angles. After obtaining the image information, this embodiment compares the image information with the image information of each food stored in the cloud to determine which foods are in the image information of the storage space inside the smart refrigerator, thereby determining which foods are already stored in the smart refrigerator. In one implementation, this embodiment can use multiple comparisons to compare the image information with the image information of each food stored in the cloud, performing the comparisons step by step to accurately determine which foods are already stored in the storage space of the smart refrigerator. For example, this embodiment can use a two-stage comparison method, where each comparison filters out image information with a similarity greater than 80%, and then the stored foods are determined from the last filtered image information.

[0076] Once the stored food is identified, this embodiment compares it with the food to be replaced in the food replacement operation command to determine whether the food to be replaced exists in the storage space of the smart refrigerator, thus confirming the food to be replaced. Next, this embodiment acquires user habit data. Since the user habit data includes the user's favorite foods, and the foods in the user habit data are sorted based on the user's preference, the target food—the user's favorite food—can be determined based on the user habit data. Therefore, this embodiment can output a food replacement prompt message to replace the food to be replaced in the food replacement command with the target food. This food replacement prompt message is delivered to the user via voice broadcast or text display, thereby facilitating timely food replacement and meeting the user's needs.

[0077] In summary, this embodiment first obtains food replacement request information generated based on voice commands. This request information indicates that the user needs to replace one type of food with another. Once the desired replacement food is identified, this embodiment determines the corresponding food replacement operation instruction based on the request information. Finally, based on the operation instruction, the corresponding operation is executed, and a food replacement prompt is output. This embodiment can provide food replacement prompts based on food replacement request information generated from the user's voice commands, facilitating timely food replacement for the user and providing a user-friendly service.
