A system for comparing subjective dialogue quality in mobile telephone systems that include at least one mobile telephone exchange operating with a number of base stations, and at least one mobile radio unit for communicating with a respective base station. A first representation of the subjective dialogue quality that is experienced by a user of a first connection in the mobile telephone system is provided and compared with a representation produced for a second connection in a mobile telephone system. The system includes a transmitter for transmitting at least one predetermined and stored speech message that constitutes a second representation of a correct dialogue quality, and second means, including speech recognition means, for receiving and evaluating the speech message transmitted. The receiver produces in accordance with the recognizable parts of the speech message, a third representation of a dialogue quality experienced the user of the system. The second and third representation are compared to produce the first representation for comparison with the representation produced for the second connection.
