It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1 to 3, an interactive listening and speaking practice system for foreign language teaching according to the present application includes: a plurality of user terminals and an application server.
Specifically, the user terminal is used for the user to operate for listening and speaking exercises. As a specific scheme, the user terminal includes: speaker, microphone, camera, treater and first type communication module.
The loudspeaker is used for outputting voice information; the microphone is used for collecting voice information; the processor is used for processing the voice information collected by the microphone and outputting the voice information through the loudspeaker. The camera is used for collecting face images of the user.
As a specific implementation scheme, the user terminal of the present application may be a smart phone, a smart tablet, or a PC. Of course, the user terminal of the present application may also be configured as a dedicated learning device.
As another part of the technical scheme of the application, the application server is used for constituting data interaction with the user terminal so as to provide the user terminal with data required by listening and speaking exercises. The application server has general server data operation and storage capacity, and specifically, the application server comprises: the system comprises a field analysis module, a semantic analysis module, a statement analysis module, a voice generation module and a second-class communication module.
The field analysis module is used for analyzing the voice information and obtaining statement fields; the semantic analysis module is used for outputting a feedback field corresponding to the statement field according to a semantic analysis result; the sentence combination module is used for generating a corresponding feedback sentence according to the feedback field and the grammatical relation; the voice generating module is used for generating feedback voice according to the feedback statement; and the second communication module is used for sending the feedback voice to the user terminal.
Specifically, the field parsing module is used for generating corresponding sentence fields according to the voice information, namely, recognizing words in the audio file. As an extension scheme, the field parsing module may be disposed in the user terminal, that is, the user terminal completes field parsing, and sends a result of the field parsing, that is, field data, to the application server for processing.
Preferably, the user terminal prompts the user to re-input the voice when any meaningful field cannot be recognized from the user voice information, and the prompt is prompted in an anthropomorphic dialogue or an image manner.
The semantic analysis module is used for analyzing the meaning of the statement field and outputting a feedback field which can correspond to the statement field, and specifically, the semantic analysis module comprises a feedback artificial neural network; the feedback artificial neural network comprises a plurality of semantic analysis models, and the semantic analysis models are trained by taking fields as input and output.
As a preferred scheme of the present application, a feedback artificial neural network is constructed, then field data of a corresponding question-answer dialog is used as training data, and contexts are respectively used as input data and output data to train the feedback artificial neural network, so that the feedback artificial neural network can output a corresponding feedback field, i.e., a response sentence, according to the input field data. The scheme is more suitable for an application scheme which definitely prescribes a listening and speaking practice scene. The trained feedback artificial neural network can perform intelligent feedback according to the input field and output the feedback field and the confidence coefficient of the feedback field. And the application server judges whether the confidence coefficient exceeds a preset value, if so, a feedback field is adopted for feedback, and if not, a self-adaptive module is adopted for feedback.
After the confidence coefficient of the feedback field exceeds a preset value, the sentence combination module adopts the feedback field to generate a corresponding feedback sentence according to the meaning, the part of speech and the grammar relation of the feedback field, the speech generation module generates feedback speech according to the feedback sentence, then the feedback speech is sent to the user terminal, and the user terminal loudspeaker pronounces the speech.
As an extension, the speech generating module may be provided in the user terminal. And when the feedback field is lower than the preset value, the current feedback field is not suitable for the current dialogue exercise. At this time, the adaptive module is responsible for feedback, specifically, the adaptive module searches the last history statement field closest to this time according to the statement field, and then correspondingly outputs the feedback field corresponding to the history statement field. If the history database has no close statement field, the reverse query statement is searched in the template library for feedback, remarking is carried out in the system, and an administrator is prompted to carry out manual processing.
Preferably, the application server further comprises: expression identification module and lip-shaped identification module.
The expression recognition module is used for generating user expression data according to the face image acquired by the camera; the expression recognition module inputs the expression data of the user to the voice analysis module as input data of the feedback artificial neural network.
The lip shape identification module is used for identifying the lip shape of the user according to the face image collected by the camera and generating lip shape identification data; the lip recognition module inputs the lip recognition data to the speech analysis module as an input data to which the artificial neural network is fed back.
The expression recognition module is mainly used for recognizing the current expression of the user so as to judge the emotion of the user and analyze the context. As a further scheme, the expression recognition module may also adopt a feedback artificial neural network for recognition, and the recognized data is input into the semantic analysis module for analysis, and the expression data of the user may be divided into: happy, general, sad, etc., and various types of data may be given with scores as degrees of distinction.
And the lip shape recognition module is used for analyzing the pronunciation of the user according to the lip shape of the user so as to assist in judging the content of the voice information of the user. The data analyzed according to the lip recognition is synchronously transmitted to the neural network for learning, so that the voice recognition accuracy can be improved according to the lip habits of the user.
As a preferred scheme of the present application, a user terminal includes: the display device comprises a display module and a simulation module, wherein the display module is used for displaying image information; the simulation module is used for generating a virtual portrait for realizing a dialogue with a user at the display module.
As an extended technical solution, the display module may further display a statement field corresponding to the user voice information and a statement field of the voice information sent by the speaker for feedback, that is, display the conversation content.
The scheme is a single-machine practice scheme of the application, namely a scheme for a user to practice listening and speaking by a single person in a learning mode.
Although the technical scheme can realize interactive man-machine conversation exercise, the mode is more suitable for a primary exercise mode due to the characteristics of the machine. I.e. there are some preset conditions for the scope of the dialog and the application scenario.
As an extension, the application server further includes: and a pairing module.
The pairing module is used for pairing the two user terminals so as to enable the voice information of the two user terminals to be interacted online. The application server pairs the two user terminals through the pairing module, and the voice information of the paired user terminals is processed by the application server and then sent to the other paired user terminal.
The pairing module is used for enabling two users needing spoken language practice to carry out interactive training.
As an extension scheme, the pairing module pairs two users, after the two users are paired, the users do not directly form a conversation through the user terminals, but the users feed back the own voice information to another user terminal after processing by a semantic analysis module and other modules in the application server, the other user terminal plays the conversation voice to the other user through a virtual portrait, the users of the other user terminal perform voice answering through the user terminals after hearing the conversation voice, and the voice information collected by the other user terminal is also fed back to the other terminal module after processing by the application server. Through the processing of the application server, two beginners can have smooth conversation practice, so that the beginners at one side of the user terminal think that the beginners are conversing with a user with more proficient spoken language, which is equivalent to that the application server analyzes the meaning expression of the user, and then the sentences conforming to the spoken language expression are obtained through corresponding algorithms, so that the spoken language level of the user at the user terminal is gradually improved.
In order to match the working mode of the pairing module, the semantic analysis module may further set a group of artificial neural networks different from the feedback artificial neural network introduced earlier, and define the artificial neural network as a forward artificial neural network, where the forward artificial neural network outputs spoken statements according to statement fields instead of feedback fields. As a preferred scheme, the application server determines whether the statement field analyzed by the field analysis module meets an expression standard pre-stored in the application server. If the expression standard is not satisfied, the input is input into the forward artificial neural network for processing, and the forward artificial neural network outputs statement information expressed based on the meaning of the user and the confidence. Similarly, a threshold determination of confidence level is required. The forward artificial neural network can learn by presetting English sentences in advance, and the specific mode is that a large number of English sentences are split into single words, then the words are used as input items of the forward artificial neural network for unordered input, and the corresponding sentences are used as output items for training the forward artificial neural network.
As a preferred scheme, the forward neural network may be used as a part of the feedback neural network, that is, the forward statement, that is, the spoken language expression statement obtained according to the statement field, is obtained first, and then the spoken language expression statement is input into a sub-artificial neural network for processing, and then the feedback statement is obtained.
Preferably, the neural network may be trained in a loop manner, the feedback statement is split, and then the forward neural network is continuously trained as training data of the normal neural network.
As an extension, when performing the pairing mode, the forward artificial neural network performs neural network model training as output data and input data of the feedback neural network (or a sub-network thereof), respectively, based on a sentence generated by the user consciousness expression and a sentence corresponding to an answer thereof. Namely, the sentence generated by inputting the sentence field by the user is used as a feedback learning material, and the neural network is trained during the pairing learning.
As a further extension, the pairing module may adopt two pairing modes. The first way is that the application server matches together users that select the same scene according to the user's selection of a voice conversation scene. The second way is that the user of the user terminal can perform voice exercise by actively adding friends, but the friends are virtual friends, and although the back of the virtual friends corresponds to real users, the application server is used as an intermediary, so fixed partners can be selected by adopting a virtual identity and friend mode to perform exercise. The third mode is that the application server analyzes the ongoing conversation theme of the user according to the semantic data of one of the users after semantic analysis, then searches other users with similar topics in the application server, and then the application server converts the self-answering into the matching user-answering.
The matching module can use the first mode and the third mode together.
As an alternative, the application server further comprises: and a data analysis module. The data analysis module is used for analyzing and summarizing the condition of the voice information module of the user analyzed by the semantic analysis module; and the data analysis module sends the analysis data to the user terminal and displays the analysis data to the user through the display module.
The data analysis module analyzes the sentence data in the voice information of the user and compares the sentence data with the sentence data processed by the artificial neural network, so that the spoken language practice condition of the user is fed back to the user. Here too, the practice situation can be analyzed by statistical question-answering validity.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
