Dialect is a part of local culture, is a great wealth, but also an important aspect of the social life chain, the rich and colorful dialects reflect the rich and colorful world, and the change of dialect reflects the change of society. Virtual reality technology integrates cutting-edge achievements in the fields of computer, electronics, and simulation. It utilizes 3D graphics, multimedia, and simulation technology, combined with advanced display and servo technology, to create lifelike virtual environments. Through devices such as computers, people can experience immersive 3D vision, touch, and even smell, as if they are truly immersed in that virtual constructed world. Designing dialect teaching space through virtual reality computing can help dialect teaching and dissemination. This paper studies the design of children’s dialect teaching space based on computer virtual reality, aiming to improve children’s dialect teaching through computer virtual technology. Through experimental tests, this paper finds that compared with the traditional design space, the space designed by using virtual reality has significantly improved efficiency, which proves that computer virtual reality technology has achieved good results in children’s dialect teaching.
