The invention relates to a voice interaction questioning system and method based on a VR virtual classroom. The system comprises a server, a voice recognition system, a helmet, and a handle. The method is characterized in that the method comprises the steps: recognizing a questioning voice, enabling a virtual student to put up a hand according to the recognized questioning voice so as to indicatethat a normal university student can allow the virtual student to answer a question, enabling the normal university student to carry out the judgment and evaluation according to the answering conditions after answering: enabling other virtual students to continue to answer the question if the answer is not correct till the answer is correct. All the virtual students who answer the question randomly ask questions, and the normal university student can carry out the unified judgment and evaluation after all questions are answered. The system provided by the invention can simulate the questioningin a real classroom, and helps the normal university student achieve the barrier-free communication with the virtual students in the VR virtual classroom.
