In order to meet these demands, the lighting industry continuously researches and develops various remote control systems and methods, including remote control technologies based on Wi-Fi, bluetooth, zigbee and other communication protocols, and matched APP applications and cloud platform services, so as to realize remote intelligent control of the LED projector.
Voice control, which is a remote, natural and convenient interaction mode, has been widely used in the field of smart home. Parameters such as the switch, the brightness and the color of the LED projection lamp are controlled through voice instructions, so that more intelligent and convenient user experience can be provided. However, the accuracy of speech recognition has been a challenge, mainly due to factors including environmental noise and unclear user intent expression.
The noisy sound of the surrounding environment may affect the accuracy of the speech recognition system, making it difficult for the system to correctly recognize the instructions of the user. Sometimes, the voice command of the user may be unclear or ambiguous, which increases the recognition difficulty of the voice recognition system and reduces the accuracy. The need for speech recognition systems to be able to cope with multiple languages and dialects for users in different locales and cultural backgrounds also increases the complexity of recognition.
Although these challenges exist, with the continuous development of speech recognition technology, innovations such as noise suppression, contextual understanding, and personalized models, the application prospect of speech control in the smart home field is still quite broad.
In one embodiment of the present application, fig. 1 is a flowchart of a remote control method of an LED projector according to an embodiment of the present application. Fig. 2 is a schematic diagram of a system architecture of a remote control method of an LED projector according to an embodiment of the present application. As shown in fig. 1 and 2, a remote control method of an LED projector according to an embodiment of the present application includes: 110, acquiring LED floodlight effect control voice acquired by recording equipment; 120, performing noise reduction treatment on the LED spotlight effect control voice to obtain a denoised LED spotlight effect control voice; 130, performing voice recognition on the noise-reduced LED spotlight effect control voice to obtain a spotlight effect control intention voice recognition result; 140, performing word granularity embedded coding on the light effect control intention voice recognition result to obtain a sequence of light effect control intention word granularity embedded coding feature vectors; 150, performing context global semantic coding on the sequence of the embedded coding feature vectors of the lighting control intention word granularity to obtain lighting control intention global semantic coding features; 160, generating complete lighting effect control intention expression text based on the global semantic coding features of the lighting effect control intention, and generating a remote lighting effect control instruction of the LED projection lamp.
In the step 110, the LED spotlight effect control voice collected by the recording device is obtained, so that the recording device can capture clear voice signals for subsequent processing and recognition, high-quality voice collection can provide more reliable input for subsequent processing, and the accuracy of voice recognition is improved. In step 120, the noise reduction processing is performed on the LED spotlight effect control voice to obtain the noise-reduced LED spotlight effect control voice, and a suitable noise reduction algorithm and parameters are selected to effectively remove the environmental noise, meanwhile, key information of the voice signal is reserved as much as possible, and the noise reduction processing can improve the quality of the voice signal, so that the subsequent voice recognition accuracy is facilitated. In step 130, voice recognition is performed on the noise-reduced LED projector lamp effect control voice to obtain a lamp effect control intention voice recognition result, a voice recognition engine suitable for a scene is selected, accuracy and instantaneity of a voice recognition model are considered, and an accurate voice recognition result is a key for realizing intelligent household lamp effect control, so that the user intention can be ensured to be correctly understood. In the step 140, the word granularity embedded coding is performed on the light effect control intention voice recognition result to obtain a sequence of feature vectors of the light effect control intention word granularity embedded coding, a proper word embedded model is selected, the voice recognition result is converted into a continuous vector representation, semantic association among words is considered, and the word granularity embedded coding can convert the voice recognition result into a computer-processable vector representation, so that a basis is provided for subsequent semantic understanding and processing. In the step 150, the sequence of the light effect control intention word granularity embedded coding feature vector is subjected to context global semantic coding to obtain the light effect control intention global semantic coding feature, the word granularity embedded coding is converted into global semantic coding in consideration of context information, so that semantic information of the whole voice instruction is better captured, and the global semantic coding can provide richer semantic information, thereby being beneficial to accurately understanding the control intention of a user. In step 160, based on the global semantic coding feature of the lighting effect control intention, a complete lighting effect control intention expression text is generated, a remote lighting effect control instruction of the LED projector is generated, natural language expression is generated by using global semantic coding, meanwhile, the generated control instruction is ensured to be accurate and clear, and the LED projector can be ensured to be remotely controlled according to the intention of a user by generating the complete control intention expression text and the accurate control instruction.
Aiming at the technical problems, the technical concept of the application is to collect the LED spotlight effect control voice through the recording equipment, and introduce the voice recognition and intention understanding technology based on deep learning at the rear end to carry out the semantic recognition and analysis of the spotlight effect control intention voice so as to accurately understand the demand semantics of the user. Like this, can reduce the interference of environmental noise effectively, perfect the expression of user's intention to improve the precision of semantic identification, and optimize and generate more accurate lamp efficiency control command, through this kind of mode, can realize the remote control to the LED projecting lamp more accurately and intelligently, promoted user experience and lighting apparatus's intelligent level.
The deep learning voice recognition technology can better recognize and filter out the environmental noise, improves the accuracy of voice instructions of users, is beneficial to reducing the interference of the environmental noise on voice recognition, and improves the robustness of the whole system. The deep learning technology has higher accuracy and generalization capability in terms of voice recognition and intention understanding, and can more accurately understand the semantics of the user, thereby improving the accuracy of semantic recognition. Through the intention understanding technology, the voice instruction of the user can be more accurately understood, and the specific requirements and scene requirements for controlling the lighting effect are included, so that the actual requirements of the user are better met. By more accurately understanding the intention of the user, a more accurate and user-desired light effect control instruction can be generated, and the accuracy and reliability of remote control are improved. Through improving the accuracy of semantic recognition and generating accurate control instructions, a user can more easily realize remote control of the LED projection lamp, so that user experience and the intelligent level of lighting equipment are improved.
Specifically, in the technical scheme of the application, firstly, the LED spotlight effect control voice acquired by the recording equipment is acquired. It should be appreciated that in actually performing remote control of LED floodlights, the command to control the voice is often disturbed by noise from the surrounding environment, such as traffic noise, human noise, electrical noise, etc. These noise can reduce the signal-to-noise ratio of the speech signal, resulting in reduced accuracy of speech recognition. Therefore, in order to reduce the interference of environmental noise on the voice signal and improve the quality and definition of the voice signal, in the technical scheme of the application, the noise reduction processing is required to be performed on the LED spotlight effect control voice so as to obtain the LED spotlight effect control voice after noise reduction.
Then, consider that in a remote control system of an LED projector, a user controls parameters such as on-off, brightness, color, etc. of the light through voice instructions. Therefore, in order to further perform noise reduction processing, so as to improve the accuracy and stability of voice recognition, so that the remote control of the LED projector is more reliable and accurate, the voice input of the user needs to be recognized to acquire the specific control intention of the user. Specifically, firstly, voice recognition is performed on the noise-reduced LED spotlight effect control voice so as to obtain a spotlight effect control intention voice recognition result. Therefore, the voice signal can be converted into a text form for further analysis and processing, so that voice instruction semantics of a user can be understood more accurately, and further, a corresponding light effect control instruction is generated, and remote control of light is realized.
Next, considering that the control requirement and intention semantics of the user exist in the light effect control intention voice recognition result, and the minimum semantic unit is word granularity. Therefore, in order to more fully and accurately perform semantic recognition and analysis on the light effect control intention voice recognition result so as to more accurately perform light effect control, in the technical scheme of the application, a sequence of embedding the light effect control intention word granularity into the coding feature vector is needed to be obtained through a word granularity encoder based on a word embedding layer after word segmentation processing is performed on the light effect control intention voice recognition result.
In a specific embodiment of the present application, performing word granularity embedded coding on the recognition result of the light effect control intention voice to obtain a sequence of feature vectors of the light effect control intention word granularity embedded coding, including: and after word segmentation processing is carried out on the light effect control intention voice recognition result, a word granularity encoder based on a word embedding layer is used for obtaining a sequence of the light effect control intention word granularity embedded coding feature vector.
It should be understood that the word granularity encoder based on the word embedding layer can convert the word-segmented light effect control intention voice recognition result into a sequence of continuous light effect control intention word granularity embedded coding feature vectors, so that semantic similarity and relevance among words can be captured better, and word meaning in voice instructions can be understood. The word granularity encoder based on the word embedding layer can convert the high-dimensional word representation into a lower-dimensional continuous vector representation, thus facilitating subsequent calculation and processing, and reducing the complexity of data. The sequence of the light effect control intention word granularity embedded coding feature vector can better express semantic information in a voice instruction, and is favorable for accurately understanding and processing the intention of a user in subsequent steps.
Further, in order to better understand the lighting effect control intention, the relationship and the context information between the individual words in the voice recognition result of the lighting effect control intention need to be considered. The transform layer based context encoder is a powerful model that can capture global semantic information in the light effect control intent speech recognition results through a self-attention mechanism. That is, it can contextually encode each word in the input sequence such that the representation of each word can be affected by the entire sequence. Based on the above, in the technical scheme of the application, the sequence of the light effect control intention word granularity embedded coding feature vector is further processed by a context encoder based on a transform layer to obtain the light effect control intention global semantic coding feature vector. By inputting the sequence of the embedded coding feature vector of the light effect control intention word granularity into the context encoder based on the transform layer, the semantic information of the whole voice instruction can be captured, so that the control intention of a user can be understood more comprehensively and accurately, and the accuracy and the intelligent level of the light effect control are improved.
In a specific embodiment of the present application, performing context global semantic coding on the sequence of the light effect control intention word granularity embedded coding feature vector to obtain a light effect control intention global semantic coding feature, including: embedding the sequence of the light effect control intention word granularity into the coding feature vector through a context encoder based on a Transformer layer to obtain the light effect control intention global semantic coding feature vector as the light effect control intention global semantic coding feature.
Further, in a specific embodiment of the present application, embedding the sequence of the lighting control intention word granularity into the coding feature vector through a context encoder based on a transform layer to obtain a lighting control intention global semantic coding feature vector as the lighting control intention global semantic coding feature, including: the sequence of embedding the light effect control intention word granularity into the coding feature vector is subjected to one-dimensional arrangement to obtain a global light effect control intention word granularity feature vector; calculating the product between the global light effect control intention word granularity feature vector and transpose vectors of the light effect control intention word granularity embedded coding feature vector in the sequence of the light effect control intention word granularity embedded coding feature vector to obtain a plurality of self-attention association matrixes; respectively carrying out standardization processing on each self-attention correlation matrix in the plurality of self-attention correlation matrices to obtain a plurality of standardized self-attention correlation matrices; obtaining a plurality of probability values by using a Softmax classification function through each normalized self-attention correlation matrix in the normalized self-attention correlation matrices; and weighting each light effect control intention word granularity embedded coding feature vector in the sequence of the light effect control intention word granularity embedded coding feature vector by taking each probability value in the plurality of probability values as a weight so as to obtain the light effect control intention global semantic coding feature vector.
And then, the global semantic coding feature vector of the lighting effect control intention is passed through a control intention perfect expressive machine based on AIGC model to obtain perfect lighting effect control intention expression text. That is, the lighting control intent global context semantic feature information is utilized to generate more complete and accurate expression text. The expression text can more accurately describe the intention and the requirement of a user, including the specific operation of the lamplight, the setting of the brightness, the color and other parameters. And further, generating a remote light effect control instruction of the LED projector based on the complete light effect control intention expression text. Therefore, the accuracy of understanding and expressing the intention of the user can be improved, so that more intelligent and accurate lamp efficiency control is realized, the remote control of the LED projection lamp can be realized more accurately and intelligently, and the user experience and the intelligent level of the lighting equipment are improved.
In a specific embodiment of the present application, based on the global semantic coding feature of the lighting control intention, generating a complete lighting control intention expression text, and generating a remote lighting control instruction of the LED projector, including: the global semantic coding feature vector of the lighting effect control intention is processed through a control intention perfect expressive machine based on AIGC models to obtain a perfect lighting effect control intention expression text; and generating a remote lamp effect control instruction of the LED spotlight based on the complete lamp effect control intention expression text.
Further, in a specific embodiment of the present application, passing the light effect control intention global semantic coding feature vector through a AIGC model-based control intention perfect expressive machine to obtain the perfect light effect control intention expression text includes: performing feature distribution optimization on the global semantic coding feature vector of the lighting effect control intention to obtain an optimized global semantic coding feature vector of the lighting effect control intention; and the optimized lighting effect control intention global semantic coding feature vector passes through the AIGC model-based control intention perfect expressive machine to obtain the perfect lighting effect control intention expression text.
Further, in a specific embodiment of the present application, performing feature distribution optimization on the global semantic coding feature vector of the lighting effect control intention to obtain an optimized global semantic coding feature vector of the lighting effect control intention, including: and performing mapping fusion correction from each sequence of the global semantic coding feature vector of the lighting effect control intention and the embedded coding feature vector of the lighting effect control intention word granularity to a fused feature distribution domain to obtain the optimized global semantic coding feature vector of the lighting effect control intention.
In the technical scheme of the application, the sequence of the light effect control intention word granularity embedded coding feature vector expresses text semantic features embedded based on word segmentation semantic coding of the light effect control intention voice recognition result, so that after the sequence of the light effect control intention word granularity embedded coding feature vector passes through a context encoder based on a Transformer layer, global text semantic features associated based on word segmentation embedded semantic context can be enhanced, and the expression effect of the light effect control intention global semantic coding feature vector is enhanced.
But this also causes the text semantic feature representation of the light effect control intent global semantic coding feature vector to deviate from the word segmentation semantic based text semantic feature representation of the light effect control intent granularity embedded coding feature vector sequence, thereby affecting the correspondence of the text representation of the refined light effect control intent expression text of the light effect control intent global semantic coding feature vector to control instructions obtained by a control intent refined expressior based on AIGC model. Accordingly, the present application contemplates improving the textual semantic feature representation of the lighting control intent global semantic coding feature vector by further fusing the lighting control intent global semantic coding feature vector with the sequence of lighting control intent word granularity embedded coding feature vectors.
In addition, in order to promote the fusion effect, the mapping fusion correction from each of the global semantic coding feature vector of the lighting effect control intention and the sequence of the embedded coding feature vector of the lighting effect control intention word granularity to the fused feature distribution domain is carried out by taking into consideration the feature distribution information representation difference caused by the global-local text semantic feature distribution difference between the global semantic coding feature vector of the lighting effect control intention and the sequence of the embedded coding feature vector of the lighting effect control intention word granularity, specifically expressed as: performing mapping fusion correction from each sequence of the global semantic coding feature vector of the lighting effect control intention and the embedded coding feature vector of the lighting effect control intention word granularity to a fused feature distribution domain by using the following optimization formula to obtain the global semantic coding feature vector of the lighting effect control intention after optimization; wherein, the optimization formula is: ; wherein/> Is the global semantic coding feature vector of the lighting effect control intention,/>Is a cascading characteristic vector obtained by cascading the sequence of the embedded coding characteristic vector of the granularity of the lighting effect control intention word, and the characteristic vector/>And/>Having the same length,/>And/>Feature vector/>, respectivelyMean and standard deviation of corresponding feature sets,/>And/>Feature vector/>, respectivelyMean and standard deviation of corresponding feature sets,/>Representing the position-by-position evolution of the feature vector, and/>Is a logarithm based on 2,/>Representing addition by position,/>Representing multiplication by location,/>And representing the optimized lighting effect control intention global semantic coding feature vector.
Here, in order to promote the mapping effect of the sequence of the global semantic coding feature vector of the lighting effect control intention and the embedded coding feature vector of the lighting effect control intention word granularity under the feature fusion scene to the fusion feature distribution domain, on the basis that the traditional weighted fusion mode has limitation on deducing the semantic space evolution diffusion mode based on feature superposition, the fusion effect of the global semantic coding feature vector of the lighting effect control intention and the sequence of the embedded coding feature vector of the lighting effect control intention word granularity is promoted by adopting a mode of combining the low-order superposition fusion mode and the high-order superposition fusion mode of the space and simulating the evolution center and the evolution track through the statistical feature interaction relation of the global semantic coding feature vector of the lighting effect control intention word granularity under the action of different evolution diffusion speed fields so as to reconstruct the semantic space diffusion under the fusion scene based on asynchronous evolution, thereby effectively promoting the projection effect in the same high-dimensional feature space. Therefore, the text semantic feature expression effect of the lamp effect control intention global semantic coding feature vector is improved, and accordingly the correspondence of the text expression of the complete lamp effect control intention expression text obtained by the lamp effect control intention global semantic coding feature vector through the control intention complete expressive machine based on AIGC models relative to a control instruction is improved. Like this, can reduce the interference of environmental noise effectively, perfect the expression of the lamp effect control pronunciation intention of user input to improve the precision of semantic identification, and optimize and generate more accurate lamp effect control command, through this kind of mode, can realize the remote control to the LED projecting lamp more accurately and intelligently, promoted user experience and lighting apparatus's intelligent level.
In summary, the remote control method of the LED projection lamp based on the embodiment of the application is explained, which can effectively reduce the interference of environmental noise, perfect the expression of user intention, thereby improving the accuracy of semantic recognition, and optimally generating more accurate lamp effect control instructions.
