Referring to fig. 3, fig. 3 is a flowchart illustrating a screen rotation control method of a tablet computer according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
step S301: and determining a first judgment result according to the screen control instruction.
It can be understood that, when the screen control instruction is a screen rotation instruction, the first judgment result may be a judgment pass; when the screen control instruction is a screen lock instruction, the first judgment result may be that the judgment is failed.
Step S302: and acquiring an audio signal at the current time, and acquiring keyword information in the audio signal.
It should be understood that, in this embodiment, whether the screen of the tablet computer to be controlled needs to be rotated may be further determined by combining the audio signal output by the user.
It is understood that the audio signal refers to an audio signal collected by the tablet computer to be controlled at the current time, and may include an audio signal sent by a user using the tablet computer to be controlled, and the keyword information refers to keywords in the audio signal, for example, keywords such as left and right keywords.
In a specific implementation, the manner of acquiring the keyword information in the audio signal may be to perform voice recognition on the audio signal through a voice recognition model to obtain text information corresponding to the audio signal, where the voice recognition model may be a deep-separation convolution recursive short-time memory network model (DFSMN), a hidden markov model, etc., then the keyword information is extracted from the text information, specifically, which keywords may be included may be preset, and then the keyword information identical to the preset keyword may be extracted from the text information.
Further, in order to obtain the keyword information effectively, in this embodiment, the step S302 includes: acquiring an audio signal at the current time, and denoising the audio signal to obtain a target audio signal; performing vector conversion on the target audio signal to obtain an audio feature vector; obtaining a keyword feature vector corresponding to a preset keyword; and determining the vector similarity between the audio feature vector and the keyword feature vector, and determining the keyword information in the target audio signal according to the vector similarity.
It can be understood that the denoising processing refers to removing noise in an audio signal, specifically, environmental noise in the audio signal can be removed first, a usage scenario of a tablet computer to be controlled, such as an indoor quiet environment, an indoor noisy environment, an outdoor quiet environment, an outdoor noisy environment, an environment with a large traffic flow, etc., can be obtained first, then all environmental noise types under the usage scenario, such as industrial noise, building noise, traffic noise, social life noise, etc., are determined, and then environmental noise corresponding to the environmental noise types is determined, so that the environmental noise in the audio signal can be removed. Then, the audio signal subjected to the environmental noise rejection can be further subjected to denoising processing through a denoising algorithm, wherein the denoising algorithm comprises wavelet transform denoising, adaptive filtering denoising, spectral subtraction denoising and the like, so that a target audio signal is obtained.
It should be understood that the target audio signal may be subjected to vector conversion to obtain an audio feature vector, and in particular, the target audio signal may be subjected to vector conversion by a preset speech feature extraction network, where the preset speech feature extraction network is a preset deep learning network for extracting feature vectors of speech, for example, a linear prediction coding network, a convolutional neural network, and the like, where the feature vectors can reflect speech information of speaking.
In a specific implementation, the keyword feature vector refers to a feature vector corresponding to a preset keyword, and the preset keyword may be a keyword related to screen rotation, for example, left, right, and the like. The vector similarity refers to the similarity between the audio feature vector and the keyword feature vector, and the formula for calculating the vector similarity can refer to the prior art, which is not repeated in this embodiment. Specifically, the audio feature vectors can be segmented, then the similarity between each segment of audio feature vectors and each keyword feature vector is calculated, when the similarity is larger than a preset threshold value, the fact that keywords exist in the segment of audio feature vectors is indicated, and since the keyword feature vectors corresponding to the keywords are known in advance, keywords corresponding to the keyword feature vectors which are similar to the segment of audio feature vectors can be used as keyword information.
Step S303: and determining a second judging result according to the screen change information and the keyword information.
It should be understood that the second determination result may include determining that the pass and the fail are determined according to the screen change information and the keyword information together, and specifically, whether the screen change information and the keyword information are matched or not may be determined, for example, the screen change information is that the screen rotation direction is left, and the keyword information is that the screen change information is right, and when the screen change information and the keyword information are not matched, the second determination result is that the fail is determined.
Further, in order to effectively obtain the second determination result, in this embodiment, the step S303 includes: determining a change track of the tablet computer to be controlled according to the screen moving direction and the screen rotating direction in the screen change information; determining distance change information between the tablet personal computer to be controlled and a user according to the change track; and when the keyword information is matched with the change track and the distance change information meets the preset distance change condition, determining that the second judgment result is passing judgment.
It can be understood that the change track refers to a movement track of the tablet computer to be controlled within a preset period of time, and specifically can be determined according to a screen movement direction and a screen rotation direction, for example, the screen movement direction is downward, the screen rotation direction is counterclockwise, and the change track is counterclockwise and downward.
It should be understood that the distance change information refers to a change condition of a distance between a user and a tablet computer to be controlled, and specifically can be determined according to a proximity sensor installed in the tablet computer to be controlled, wherein the proximity sensor can acquire the distance between the tablet computer to be controlled and other objects, and also includes the distance between the tablet computer to be controlled and the user, and the distance change information is obtained according to the change condition of the distance.
