Fig. 2 is a method for controlling a washing machine by voice according to an embodiment of the present invention, where the method of the present embodiment may be executed by a processing unit in a main control board 2, and as shown in fig. 2, the method of the present embodiment may include the following steps.
S101, voice data input by a user are received.
The washing machine is provided with a voice acquisition device which can be a microphone, and when the washing machine is in a standby state or an operating state, the microphone acquires voice data.
S102, whether the voice data contain preset keywords or not is recognized.
The voice module of the washing machine generally needs a voice wake-up word to wake up, and the wake-up word is, for example, small, high, and the like. The voice recognition module recognizes the voice data to obtain text content corresponding to the voice data, if the text content corresponding to the voice data contains preset keywords, step S103 is executed, and if the text content corresponding to the voice data does not contain the preset keywords, step S106 is executed.
The preset keywords include any one or more of the following words: starting, suspending, opening a door, starting or shutting down.
The key words can be flexibly set by a user according to needs, the intelligent washing machine can be connected with the control device, the washing machine is set through app on the control device, and the control device can be a mobile phone, a tablet computer, a desktop computer and the like.
The method comprises the steps that a user sets keywords through app on control equipment, the control equipment sends setting information to the intelligent washing machine according to the setting of the user, the setting information comprises preset keywords, and the intelligent washing machine sets the preset keywords according to the setting information.
And S103, determining the age of the sound-producing user corresponding to the voice data through voiceprint recognition.
The voiceprint refers to the sound wave frequency carrying language information displayed by an electroacoustic instrument, belongs to biological authentication as fingerprints, palm prints, facial images, irises and handwriting, and can identify different people, people of different ages and people of different sexes through voiceprint identification.
The age and gender difference of the human can be reflected on the whole pronunciation system, particularly the shape of the vocal tract, so that the vocal print parameters are changed, and the corresponding difference can be extracted from various vocal print parameters. The human vocal organs include: lung, trachea, larynx, pharynx, nose, mouth. The part of the larynx is the glottis and the passage from the glottis to the lips is the vocal tract. The shape of the vocal tract is mainly determined by the position of the lips, jaws, and tongue. The varying shape of the vocal tract results in the emission of different sounds.
In one implementation mode, voiceprint parameters are extracted from voice data, the extracted voiceprint parameters are matched with voiceprint parameters of a plurality of age stages, and if the extracted voiceprint parameters are successfully matched with the voiceprint parameters of a first age stage of the voiceprint parameters of the age stages, the maximum value of the first age stage is determined to be the age of a speaking user.
Optionally, the voiceprint parameters include one or more of the following parameters: gene period, short-term frequency, short-term energy, short-term zero-crossing rate, cepstrum, Linear Prediction Coefficient (LPC) parameter, Mel-scale frequency Cepstral Coefficients (MFCC) parameter.
The voiceprint parameters of people in different age stages are different, the voiceprint parameters in different age stages can be obtained through a large amount of voice data, and if the voiceprint parameters comprise gene periods, short-time frequency and short-time energy, 3 age stages, namely 3-8 years old, 9-15 years old and more than 15 years old are provided, the voiceprint parameters in the three age stages are different in value. Exemplary values for the gene cycle from 3 to 8 years old are a1-a2, short-term frequency b1-b2, short-term energy c1-c 2; the gene cycle of 9-15 years old is a3-a4, the short-term frequency is b3-b4, and the short-term energy is c3-c 4; the gene cycle above 15 years old is a5-a6, the short-term frequency is b3-b4, and the short-term energy is c3-c 4.
And during matching, comparing the gene cycle of the extracted voice data with the gene cycles of the three age groups, comparing the short-time frequency of the extracted voice data with the short-time frequencies of the three age groups, and comparing the short-time energy of the extracted voice data with the short-time energy of the three age groups. And if the gene cycle, the short-term frequency and the short-term energy of the extracted voice data all belong to the value ranges of the gene cycle, the short-term frequency and the short-term energy corresponding to the age range of 9-15 years, determining that the voiceprint parameters of the extracted voice data are matched with the voiceprint parameters corresponding to the age range of 9-15 years, and taking the maximum age value 15 in the age range of 9-15 years as the age of the voice-producing user.
In another possible implementation manner, similarity between the extracted voiceprint parameters and the voiceprint parameters corresponding to each age stage is calculated, and when the similarity between the extracted voiceprint parameters and the voiceprint parameters of the first age stage is greater than a similarity threshold, it is determined that the extracted voiceprint parameters are successfully matched with the voiceprint parameters of the first age stage. And when the similarity between the extracted voiceprint parameters and the voiceprint parameters in the first age stage is less than or equal to the similarity threshold, determining that the extracted voiceprint parameters are not matched with the voiceprint parameters in the first age stage or the matching fails.
In another implementation, a voiceprint recognition model can be obtained by training a large number of voice data samples, and after voice data is input into the voiceprint recognition model, the age of a voice user corresponding to the voice data can be obtained. The voiceprint recognition model can be obtained by adopting deep neural network model training.
And S104, judging whether the age of the sounding user is smaller than a preset age.
The preset age is the corresponding age of the child, for example, 12 years, 15 years, etc., when the age of the speaking user is smaller than the preset age, step 105 is executed, and when the age of the speaking user is not smaller than (i.e., greater than or equal to) the preset age, step 106 is executed.
S105, prohibiting the operation corresponding to the voice data.
When the age of the sounding user is smaller than the preset age, the sounding user is indicated as a child, and the action corresponding to the voice data is forbidden to be executed in order to avoid potential safety hazards possibly brought by child operation.
After the operation corresponding to the voice data is prohibited, the operation corresponding to the voice data is not executed, and the washing machine continues to operate.
If the washing machine has the child lock function, the action corresponding to the execution of the voice data is specifically prohibited as follows: when the child lock function is started, any other operation key can lose the control function temporarily, so that the danger caused by curious misoperation of children is avoided.
After the child lock function is turned on, the washing machine can respond to other external operations of the user only if the child lock function is released. If the user does not release the child lock function, the washing machine operates according to the set operation mode and does not respond to other external operations of the user during the operation, and after the set operation mode is finished, the washing machine releases the child lock function. For example, if the user sets a quick-wash mode, the washing machine operates in the quick-wash mode after the child lock function is activated, and no other operation is responded to in the process.
Optionally, on the premise that the washing machine has the child lock function, when the action corresponding to the voice data is prohibited, the child lock function may not be turned on, and only the action corresponding to the voice data is prohibited.
If the washing machine is connected with the control equipment, when the age of the sounding user is determined to be smaller than the preset age, notification information can be sent to the control equipment connected with the washing machine, the notification information is used for notifying children to operate the washing machine, and parents can know the situation according to the notification information and take corresponding measures.
Or when the age of the sounding user is determined to be smaller than the preset age, sending a notification message to a preset mobile phone number, namely sending the notification message in a short message mode.
When the age of the sounding user is determined to be smaller than the preset age, optionally, the user can be prompted by voice that the action corresponding to the voice data cannot be executed.
And S106, executing the action corresponding to the voice data.
When the age of the voice user is larger than or equal to the preset age, the voice data are not sent by children and are normal voice control instructions of the user to the washing machine, and the action corresponding to the voice data is determined according to the recognized characters corresponding to the voice data.
For example, when the action corresponding to the voice data is pause, the washing machine is controlled to pause, and when the action corresponding to the voice data is shutdown, the washing machine is controlled to shut down.
In the embodiment, voice data input by a user is received, whether the voice data contains preset keywords or not is identified, if the voice data contains the preset keywords, the age of a sound-producing user corresponding to the voice data is determined through voiceprint identification, and when the age of the sound-producing user is smaller than the preset age, the action corresponding to the voice data is forbidden to be executed; and when the age of the sounding user is not less than the preset age, executing the action corresponding to the voice data. Through the age of the sound-producing user corresponding to the recognized voice data, when the sound-producing user is determined to be a child, the action corresponding to the voice data is forbidden to be executed, the potential safety hazard of the child caused by curious misoperation is reduced, and the use safety of the washing machine is improved.
