The present invention provides a virtual reality speech control method and device. The method comprises: receiving a request for opening a speed interface sent by a virtual reality application program; opening the speed interface according to the request, and receiving the input speed information through the speed interface; converting the speech information to the text information, and performing standardization of the text information to generate an intention object in accordance with a presetting standard; identifying the intention object based on the presetting standard set, and obtaining the instruction corresponding to the intention object; and sending the instruction to the virtual reality application program to allow the virtual reality application program to execute the instruction and feed back the execution result. According to the invention, the virtual reality speech control method and device can realize the control of the scene conversion in the virtual reality process and the virtual reality through the speed so as to avoid the repeatability and the inconvenience of the hardware control and improve the interaction reality.
