Embodiment

[0036] The embodiment structure of the voice interactive questioning system based on the VR virtual classroom of the present invention, such as figure 1 As shown, it includes a pickup 1; a speech recognition system 2; a speech keyword library 3; a server 4; a feedback speech 5; a virtual student 6;

[0037] The pickup 1 is used to input the voice of the normal students in class into the virtual classroom system, so as to prepare for the voice recognition of the subsequent system.

[0038] The speech recognition system 2 is used to recognize the sound picked up by the front pickup, extract keywords in the speech, and convert it into a type that the server can execute.

[0039] The voice keyword library 3 is used to compare the keywords extracted in the voice recognition system with the keywords in the library. When the comparison is successful, the voice is forwarded to all virtual students in class, and the students have the voice signal After the input, a corresponding signa...

Abstract

The invention relates to a voice interactive questioning system and method based on a VR virtual classroom. Including server, speech recognition system, helmet and controller. The features of this patent include: recognizing the voice of the question, and raising the hand of the virtual student according to the recognized voice to indicate that the normal student can ask him to answer the question. After the answer is completed, the normal student will judge and evaluate according to the answer, such as answer If it is not correct, other virtual students can continue to answer until the answer is correct. All virtual students answering questions are asked randomly, and normal students can make unified judgments and evaluations after all answers are completed. The present invention imitates the questioning in the real classroom by means of the VR virtual classroom questioning system, helping normal students to realize barrier-free communication with virtual students in the VR virtual classroom.

Description

technical field [0001] The invention relates to a questioning system and method, belonging to the field of virtual reality technology, in particular to a voice interactive questioning system and method based on a VR virtual classroom. Background technique [0002] With the gradual maturity and application of virtual reality technology, it has been applied in many fields at home and abroad, such as psychotherapy training, training in high-cost or high-risk places, education and training, and interview training for newcomers. Through virtual environment training, it assists practitioners to find problems in the training process and gives timely guidance and help, enhances the skills of practitioners or improves the training efficiency of practitioners, without adding any additional costs, and can be reused many times. This is a clear advantage of training in a virtual environment. [0003] However, virtual reality technology also has defects in many current application fields...
