Smart home voice control system combined with video channel and control method thereof

The invention discloses a smart home voice control system combined with a video channel and a control method thereof. The system comprises a gesture detection module, a human face detection module, a recognition system module, a command judgment module and a command display and confirmation module which are sequentially connected. The recognition system module comprises a lip language part and a voice part, wherein the lip language part comprises a human face tracking and positioning module, a lip language video input module and a lip language recognition module which are sequentially connected; and the voice part comprises a voice input module and a voice recognition module which are sequentially connected. By detecting control gestures and recognizing human faces and lip language information to supplement the recognized voice information, the accuracy of control commands is improved and the feasibility of using voices to control a smart home is increased. The smart home voice control system combined with the video channel has very strong interference resistance, can be widely used for various complex environment modes and is particularly suitable for the situation of high noise because of a great number of people in home environments.

Identification verifying system for living human body for electronic payment

The invention provides an identification verifying system for a living human body for electronic payment, so as to overcome defects existing in the prior art. Through various voice-shape-image biometric feature recognition of face recognition, voice recognition, voiceprint recognition and lip language recognition, whether a user is an operator or not and whether the user is an intelligent living body or not are verified, through a client of the electronic payment and the interactive communication of a server, the feature information of a face, a voice, a voiceprint and a lip language is extracted out from a video and an audio obtained by the client of the electronic payment through the client of the electronic payment, and less data flow is used and transmitted into a server terminal through the Internet so as to perform the feature information of the face, the voice, the voiceprint and the lip language. Direct contact between the identification verifying system and the operator is not needed, whether the user is the operator or not and whether the user is the intelligent living body or not are verified, the identification verifying system is convenient to use, easy to accept by the operator and good in customer experience, and besides, an additional hardware is not needed.

Intelligent customer service response method and system

The invention discloses an intelligent customer service response method and system, relates to the technical field of intelligent customer service, and can solve the problems of low response efficiency and poor user experience caused by relying on manual customer service in the prior art. The method comprises the steps of preprocessing the customer service historical chat statements to export customer service corpora, and conducting the word segmentation training on the customer service corpora to obtain a language recognition model; carrying out intention identification on corpora asked by auser to match a corresponding service module, carrying out retrieval analysis in an elasticsearch database corresponding to the service module by utilizing an intention identification result, and summarizing output associated keyword answers to form a pre-selected data set; taking a text formed after word segmentation of the question corpus of the user as an input, and carrying out Elasticsearch retrieval in a pre-selected data set to output candidate keyword answers; converting the segmented keywords and the candidate keyword answers into word vectors respectively, calculating the similaritybetween the segmented keywords and the candidate keyword answers in pairs by using a WMD algorithm, and selecting the keyword answers based on the similarity values to respond to the user.

Retrieving matching documents by queries in any national language

Search time is reduced with a search engine that includes a bi-directional inverted index facility which can be accessed with a keyword search in one of a number of languages and provide a listing of documents contained in all of those languages. The keywords in all supported languages are preferably stored in an inverted index lookup table cross referenced to documents in those language containing the keywords. Keywords with the same meaning in different languages are accessible together when that keyword in one of the languages is queried. The search engine containing the table can identify pertinent documents either in a selected language, a second language or in all supported languages, as determined by the user. Information about each document can include not only the identity of the document but also information used in ranking the documents such as the number of times that a keyword appears in that document, and the keywords proximity to other keywords. The use of the inverted index table therefore reduces search time by eliminating the need for translation of keywords, their identification in documents and accumulating of ranking information at search runtime and avoids inaccuracies which may result from full text translations of documents.

Method and device for operating and controlling virtual center console of Blind-operation-supported automobile by gestures

The invention discloses a method and a device for operating and controlling a virtual center console of a blind-operation-supported automobile by gestures. By the method and the device, a user can conveniently use gestures to perform corresponding operation and control on a center console touch screen during driving without transferring road driving sight line, and by an automobile blind operation function, the shortcoming of searching complex and various mechanical buttons in the conventional driving room to control the conventional automobile is well overcome; and meanwhile, the virtual center console integrates a gesture language library module, a gesture analysis and processing module, a gesture language recognition module, a gesture language library management module, a gesture operation and control execution module and a gesture operation and control security mechanism management module, and because of cooperative work of the modules, gesture language operation and control has the characteristics that the gesture language operation and control is easy and convenient to use, gesture operation and control windows are independent, gesture language meaning is unique, a gesture language can be modified, an operation and control mechanism is safe and the like, and convenient, rapid, friendly and safe operation and control experiences of the automobile center console can be brought to the user according to specific requirements.

Lip language recognition method and device, computer equipment and storage medium

The invention discloses a lip language recognition method and device, computer equipment and a storage medium. The lip language recognition method comprises the following steps: carrying out standardization processing on a frame rate of an obtained original video, and separating the obtained standard video to obtain an effective audio stream and an effective video stream; tracking a human face in the effective video stream by using a human face recognition algorithm, extracting a mouth area in the human face, and obtaining a frame lip action video so as to obtain a lip image sequence; segmenting the lip image sequence by adopting a sequence segmentation rule to obtain a segmented image sequence; sequentially inputting the segmented image sequences corresponding to the lip image sequences into a lip image recognition model for recognition, and obtaining a lip image recognition result; inputting the effective audio stream into a speech recognition model to obtain a speech recognition result; and when the similarity between the lip image recognition result and the original video reaches a preset value, taking the lip image recognition result as a lip language recognition result of the original video so as to ensure the accuracy of the lip image recognition result.
