and b, comparing the extracted keywords with the keywords of each cooking mode in the cooker to determine the cooking mode matched with the keywords of the text information.
Step S30, acquiring attribute values of cooking parameters according to the voiceprint characteristics in the cooking mode;
after determining the cooking mode of the cooker according to the voice instruction, acquiring an attribute value of the cooking parameter according to the voiceprint feature in the determined cooking mode, specifically, referring to fig. 3, the step S30 includes:
step S31, comparing the voiceprint features with prestored voiceprint features of the cooking mode to judge whether prestored voiceprint features matched with the voiceprint features exist or not;
and step S32, if the pre-stored voiceprint characteristics matched with the voiceprint characteristics exist, acquiring the attribute values of the cooking parameters corresponding to the pre-stored voiceprint characteristics according to the mapping relation between the pre-stored voiceprint characteristics and the attribute values of the cooking parameters.

After the pre-stored voiceprint features are obtained in the cooking mode, the extracted voiceprint features are compared with the pre-stored voiceprint features to judge whether the pre-stored voiceprint features matched with the extracted voiceprint features exist in the cooker or not, if yes, the cooker records the pre-stored voiceprint features in the cooking mode in advance, and at the moment, the attribute values of the cooking parameters corresponding to the pre-stored voiceprint features can be directly obtained.
In this embodiment, in the determined cooking mode, the selectable pre-stored voiceprint characteristics have a one-to-one mapping relationship with the attribute values of the cooking parameters, for example, in the steak-baking cooking mode of the oven, the cooking parameters of the a pre-stored voiceprint characteristics are cooking temperature and cooking time of 3 minutes of cooking, and the cooking parameters of the B pre-stored voiceprint characteristics are cooking temperature and cooking time of 7 minutes of cooking.

According to the voice control method for the cooker, when voice information is received, a voice instruction and voiceprint features are extracted from the voice information, then a cooking mode of the cooker is determined according to the voice instruction, then under the determined cooking mode, attribute values of cooking parameters are obtained according to the voiceprint features, and finally the cooker is controlled to operate according to the attribute values of the cooking parameters. After the voice information is received, the attribute value of the cooking parameter in the cooking mode can be determined according to the voiceprint feature of the voice information as long as the cooking mode of the cooker is determined, the cooker is subsequently controlled to operate according to the attribute value, even if the voice information is a fuzzy password, the cooker can be accurately controlled according to the voiceprint feature of the voice information, and the flexibility of controlling the cooker is improved.
Further, a second embodiment of the sound control method of the cooker of the present invention is proposed based on the first embodiment.

and step S33, if the pre-stored voiceprint characteristics matched with the voiceprint characteristics do not exist, acquiring the recommended attribute value of the cooking parameters in the cooking mode so as to control the cooker to operate according to the recommended attribute value in the following process.
In this embodiment, after comparing the extracted voiceprint feature with the pre-stored voiceprint feature to determine whether the pre-stored voiceprint feature matching the extracted voiceprint feature exists in the cooking device, if the pre-stored voiceprint feature matching the voiceprint feature does not exist, it is indicated that the cooking device does not record the pre-stored voiceprint feature in the cooking mode in advance, at this time, a preset recommended attribute value of the cooking parameter may be obtained in the cooking mode, and the cooking device is controlled through the preset recommended attribute value of the cooking parameter. It can be understood that, in the embodiment, even if the voiceprint feature is not recorded in advance in the cooking mode, the control of the cooker can be realized according to the preset recommended attribute value of the cooking parameter, so that the flexibility of the control of the cooker is improved.
In this embodiment, the step of "obtaining the recommended attribute value of the cooking parameter in the cooking mode" includes:
step c, judging whether the attribute value of the historical cooking parameter is recorded in the cooking mode;
step d, if the attribute values of the historical cooking parameters are recorded in the cooking mode, acquiring the attribute values of the historical cooking parameters of each time;
step e, calculating the ratio of the attribute values of the historical cooking parameters in the total times;
step f, calculating a recommended attribute value of the cooking parameter according to the ratio of the attribute values of the historical cooking parameters and the attribute values of the historical cooking parameters;
and g, acquiring the calculated recommended attribute value.
That is, if the cooker does not have a pre-stored voiceprint feature matching the voiceprint feature, it is further determined whether an attribute value of a historical cooking parameter is recorded in the cooking mode, and if the attribute value of the historical cooking parameter is recorded in the cooking mode, it indicates that the cooker has been previously operated according to the attribute value of the historical cooking parameter in the cooking mode, and the cooker records the attribute value of the historical cooking parameter, then the cooker may acquire the attribute value of the historical cooking parameter for each time to calculate the recommended attribute value of the cooking parameter when the cooker records the attribute value of the historical cooking parameter in the cooking mode. Namely, the attribute value of each historical cooking parameter is obtained, and then the ratio of the attribute value of each historical cooking parameter in the total times is calculated, specifically, according to the following calculation formula: and Pn is the ratio of the attribute value of each historical cooking parameter to the total times, wherein m represents the total times of the cooker in the cooking mode, n represents the historical cooking parameter of the nth time, and the maximum value of n is m. After the ratio of the attribute value of each historical cooking parameter in the total times is calculated through the calculation formula, the recommended attribute value of the cooking parameter is calculated by combining the attribute values of each historical cooking parameter.
It should be understood that the cooking mode of the cooker exemplified above is a steak-baking cooking mode of an oven, and the cooking parameters in the cooking mode include cooking time and cooking temperature, and therefore, if x and y are used to represent the cooking parameters, the recommended attribute values of the cooking parameters can be calculated according to the following calculation formula D ═ x1 × p1+ x2 × p2+ … … + xn × pn, y1 × p1+ y2 × p2+ … … + yn × pn, where x1 and y1 represent the attribute values of the first-time historical cooking parameters, x2 and y2 represent the attribute values of the second-time historical cooking parameters, and xn and yn represent the attribute values of the nth-time historical cooking parameters. And calculating the recommended attribute values of the cooking parameters x and y through the calculation formula, and finally obtaining the calculated recommended attribute values so as to control the cooker to operate according to the recommended attribute values in the following process.
Further, in order to improve accuracy of controlling the cooker, the step g includes:
and rounding the calculated recommended attribute value by adopting a rounding function to obtain a rounded recommended attribute value, and obtaining the rounded recommended attribute value.
In this embodiment, a down-rounding function may be optionally used to round the calculated recommended attribute value, that is, D ═ { INT (x1 × p1+ x2 × p2+ … … + xn × pn), INT (y1 × p1+ y2 p2+ … … + yn × pn) }, to obtain a rounded recommended attribute value, and finally obtain the rounded recommended attribute value, so that the cooker is controlled to operate according to the rounded recommended attribute value in the following process.
In this embodiment, when the cooking device does not have the pre-stored voiceprint feature matched with the voiceprint feature, the recommended attribute value of the cooking parameter is obtained according to the attribute value of the historical cooking parameter in the cooking mode, so that the cooking device is controlled to operate according to the recommended attribute value of the cooking parameter, and the flexibility and the intelligence of the operation of the cooking device are improved. In addition, after the recommended attribute value of the cooking parameter is acquired, the calculated result may contain a decimal point, so that the calculated recommended attribute value is rounded through a rounding function, so that the cooker is controlled to operate according to the acquired recommended attribute value, and the flexibility of controlling the cooker is improved.
Further, a third embodiment of the sound control method of the cooker of the invention is proposed based on the second embodiment.
In this embodiment, after the step c, the method further includes:
and h, if the attribute value of the historical cooking parameter is not recorded in the cooking mode, acquiring a preset attribute value as a recommended attribute value of the cooking parameter.
In this embodiment, after determining whether the cooker records the attribute value of the historical cooking parameter in the determined cooking mode, if it is found that the attribute value of the historical cooking parameter is not recorded in the cooking mode determined by the cooker, it indicates that the cooker is operated in the cooking mode for the first time, and has not been operated in the cooking mode before, for example, the oven is in the first-time use beefsteak roasting mode, and has not been used before, so the cooker does not record the attribute value of the cooking parameter in the beefsteak roasting mode. At this time, in order to ensure the normal operation of the cooking device, a preset attribute value may be obtained, where the preset attribute value may be an attribute value set by a user in advance, for example, a specific numerical value of cooking time and cooking temperature is set by the user in advance in a steak-baking cooking mode, and then, after the preset attribute value is obtained, the obtained attribute value may be used as a recommended attribute value of a cooking parameter in the cooking mode.
In this embodiment, when the cooker does not record the attribute value of the historical cooking parameter in the determined cooking mode, in order to ensure the normal operation of the cooker, the preset attribute value may be obtained, and the obtained attribute value is used as the recommended attribute value of the cooking parameter in the cooking mode, so that the cooker is controlled to operate according to the recommended attribute value in the subsequent step, and the flexibility of controlling the cooker is improved.
Further, a fourth embodiment of the sound control method of the cooker of the present invention is proposed based on the first to third embodiments. In this embodiment, referring to fig. 5, the step S40 includes:
step S41, outputting the acquired attribute value of the cooking parameter in the display interface of the cooker for the user to confirm;
and step S42, when receiving the confirmation instruction, controlling the cooker to operate according to the attribute value of the cooking parameter.
In this embodiment, after the cooker acquires the attribute value of the cooking parameter according to the voiceprint feature in the determined cooking mode, the acquired attribute value of the cooking parameter is output in a display interface of the cooker for a user to confirm, and after the user confirms, the cooker can operate according to the attribute value of the cooking parameter.
In the embodiment, before the operation of the cooker is controlled, the cooker outputs the prompt information to enable the user to confirm, and then the cooker is controlled to operate after the user confirms, so that the attribute value of the cooking parameter for controlling the operation of the cooker is prevented from being different from the actual requirement of the user, and the accuracy of controlling the cooker is improved.
