detailed description

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

A smart home appliance control method and apparatus according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

The present invention provides a method for controlling a smart home appliance, which includes: acquiring voice information input by a user; and identifying voice information based on the voice recognition model to obtain voice information corresponding thereto. The matching score between the wake-up words; determining the wake-up mode of waking up the smart home appliance according to the matching score to wake up the smart home appliance.

1 is a flow chart of a smart home appliance control method in accordance with one embodiment of the present invention.

As shown in FIG. 1, the smart home appliance control method includes:

S101. Acquire voice information input by a user.

In this embodiment, a user wants to control a smart home appliance by voice, and can voice the voice message to the smart home appliance to wake up the smart home appliance. For example, the user feels that the indoor temperature is a little low, and wants to adjust the temperature. At this time, the user can speak voice information such as “power on” to the smart air conditioner, so that the smart air conditioner receives the voice information.

S102. Identify voice information based on a voice recognition model to obtain a matching score between the voice information and its corresponding wake-up word.

After acquiring the voice information input by the user, the acoustic features of the voice information may be extracted, and the acoustic features are input into the voice recognition model, and the voice information input by the user is recognized by the voice recognition model, thereby calculating the recognition result corresponding to the recognized voice information. A match score with a pre-set wake-up word. Wherein, the range of the matching score can be set from 0 to 100 points, wherein 0 points indicates that the input voice information does not match the wake-up word completely, and 100 points indicates that the input voice information completely matches the wake-up word, that is, the matching score The higher the match, the better. Of course, the matching score range can also be set from 0 to 50 points, 0 points to 200 points, etc., and the matching score range can be set according to actual needs.

S103. Determine, according to the matching score, an awake mode for waking up the smart home appliance to wake up the smart home appliance.

Specifically, after the matching score is obtained, the awake mode of the smart home appliance corresponding to the matching score may be determined according to the matching score, and the smart home appliance is woken up. When the matching score is greater than or equal to the first preset threshold, the smart home appliance is woken up in the first wake mode. The first awake mode may be that the smart home appliance turns on the light indication and simultaneously plays the voice wakeup information. That is to say, when the matching score is greater than or equal to the first preset threshold, the smart home appliance turns on the light indication and simultaneously plays the voice wakeup information, and the double reminder notifies the user that the smart home appliance is woken up. When the matching score is less than the first preset threshold and greater than or equal to the second preset threshold, the smart home appliance is woken up in the second wake mode, such as turning on the light indication. The second preset threshold is smaller than the first preset threshold. That is to say, when the matching score is less than the first preset threshold and greater than or equal to the second preset threshold, the smart home appliance is still awakened, but the voice wakeup information is not played, and only the light indication is used to remind the user that the smart home appliance has entered the awake state, avoiding Playing the voice wakeup message disturbs the user. Among them, the light indication can be static, that is, the light remains in a constant state. It can also be dynamic, such as the light can be in a state of slow flashing, fast flashing, and the like.

The reason for setting two preset thresholds here is that if the smart home appliance is mistakenly awakened, its matching score is generally relatively low. When users really need to wake up smart appliances, the matching scores obtained are often relatively high. Therefore, in the embodiment, the first preset threshold and the second preset threshold are set to ensure that the smart home appliance does not emit a voice reminder in a state of being awake by mistake, thereby avoiding bothering the user.

A specific example is as follows: As shown in FIG. 2, assuming that the matching score range is set to 0 to 100 points, the first preset threshold may be set to 80 points in advance, and the second preset threshold is set to 60 points. When the user needs to wake up the smart home appliance, voice information can be input. The voice recognition device in the smart home appliance can identify and match the voice information. When the matching score between the voice information and the wake-up word is less than 60 points, it means that the two do not match, so the smart home appliance is not woken up. When the matching score is greater than or equal to 60 points and less than 80 points, it indicates that the voice information matches the wake-up word, and the smart home appliance can be woken up. However, since the matching degree between the two is not high, the smart home appliance has been awakened only by turning on the light indication. When the matching score is greater than or equal to 80 points, it indicates that the matching degree of the two is relatively high. The user can be prompted to wake up by turning on the light indication and simultaneously playing the voice wake-up information.

The intelligent home appliance control method proposed by the present invention will be described in detail below by taking a smart air conditioner as an example.

3 is a flow chart of a smart air conditioning control method in accordance with one embodiment of the present invention.

As shown in FIG. 3, the steps of the smart air conditioner control method are:

S301. Acquire a voice information "Ice and Snow Kingdom".

At some point, the smart air conditioner in a user's home received the voice information "Ice Snow Kingdom." It can be understood that the voice information may be voice information input by the user to wake up the smart air conditioner, or may be voice information played on the television or the broadcast.

S302, the matching score between the acquired voice information and the wake-up word "Ice and Snow Kingdom" of the smart air conditioner is 70 points.

Assume that the matching score ranges from 0 to 100, where 0 indicates that the acquired voice information does not match the wake-up word of the smart air conditioner completely, and 100 indicates that the acquired voice information completely matches the wake-up word of the smart air conditioner, and the A preset threshold is set to 80 minutes, and a second preset threshold is set to 60 minutes.

After acquiring the voice information "Ice and Snow Kingdom", the voice recognition model is used to identify the voice information, thereby calculating a matching score between the recognition result corresponding to the recognized voice information and the wake word "Ice Snow Kingdom", and the matching score is calculated to be 70 points.

S303, turning on the light indication.

Since the matching score between the voice information and the wake-up word is 70 points between 60 points and 80 points, that is, the voice information matches the wake-up word, but the degree of matching is not high. Therefore, the smart air conditioner only turns on the light indication to remind the user that the smart air conditioner is woken up, and does not perform the voice play wake-up information, so as not to disturb the user.

The smart home appliance control device according to the embodiment of the present invention will be described below with reference to FIG. 4 is a schematic structural diagram of a smart home appliance control apparatus according to an embodiment of the present invention.

As shown in FIG. 4, the smart home appliance control apparatus may include: an acquisition module 410, an identification module 420, and a wakeup module 430.

The obtaining module 410 is configured to obtain voice information input by the user.

In this embodiment, a user wants to control a smart home appliance by voice, and can voice the voice message to the smart home appliance to wake up the smart home appliance. For example, the user feels that the indoor temperature is a little low, and wants to adjust the temperature. At this time, the user can speak voice information such as “power on” to the smart air conditioner, so that the acquisition module 410 acquires the voice information.

The identification module 420 is configured to recognize the voice information based on the voice recognition model to obtain a matching score between the voice information and its corresponding wake-up word.

The wake-up module 430 is configured to determine, according to the matching score, the wake-up mode of the wake-up smart home appliance to wake up the smart home appliance.

The wake-up module 430 is configured to wake up the smart home appliance in the first wake-up mode when the match score is greater than or equal to the first preset threshold; or to wake up in the second wake-up when the match score is less than the first preset threshold, and is greater than or equal to the second preset threshold The mode wakes up the smart home appliance, wherein the second preset threshold is less than the first preset threshold.

The wake-up module 430 is used to turn on the light indication and play the voice wake-up information.

The wake-up module 430 is used to turn on the light indication.

Among them, the light indication can include static and dynamic.

Specifically, after the matching score is obtained, the awake mode of the smart home appliance corresponding to the matching score may be determined according to the matching score, and the smart home appliance is woken up. When the matching score is greater than or equal to the first preset threshold, the wake-up module 430 wakes up the smart home appliance in the first wake-up mode. The first awake mode may be that the smart home appliance turns on the light indication and simultaneously plays the voice wakeup information. That is to say, when the matching score is greater than or equal to the first preset threshold, the smart home appliance turns on the light indication and simultaneously plays the voice wakeup information, and the double reminder notifies the user that the smart home appliance is woken up. When the matching score is less than the first preset threshold and greater than or equal to the second preset threshold, the waking module 430 wakes up the smart appliance in the second awake mode, such as turning on the light indication. The second preset threshold is smaller than the first preset threshold. That is to say, when the matching score is less than the first preset threshold and greater than or equal to the second preset threshold, the smart home appliance is still awakened, but the voice wakeup information is not played, and only the light indication is used to remind the user that the smart home appliance has entered the awake state, avoiding Playing the voice wakeup message disturbs the user. Among them, the light indication can be static, that is, the light remains in a constant state. It can also be dynamic, such as the light can be in a state of slow flashing, fast flashing, and the like.

In summary, the smart home appliance control apparatus according to the embodiment of the present invention identifies the voice information based on the voice recognition model, and obtains a matching score between the voice information and the corresponding wake-up word, and determines the corresponding wake-up smart home appliance according to different matching scores. The wake-up mode can effectively reduce the impact of false wake-up on the user.
