Disclosed are a voice quality evaluation method and device. The method comprises: acquiring a first transmission error code parameter and a second transmission error code parameter, wherein the first transmission error code parameter is an uplink channel transmission error code parameter of a first user equipment, and the second transmission error code parameter is a downlink channel transmission error code parameter of a second user equipment; and according to the first transmission error code parameter and the second transmission error code parameter, generating an end-to-end voice quality index from the first user equipment to the second user equipment. By means of the method and device in embodiments of the present invention, a network node can calculate the end-to-end VQI among different user equipment, so that the voice quality from one end to the other end can be evaluated using the end-to-end VQI, thereby satisfying the requirements for end-to-end voice quality evaluation among different user equipmen
