Abstract
In a telephone switching system, a multifrequency code receiver unit is replaced by a voice-controlled dial signal receiver unit connected to the switching network via an adapter unit. The voice-controlled dial signal receiver unit contains a voice recognition unit, a voice output unit, and a control unit. A multifrequency code receiver is connected in parallel with the voice-controlled dial signal receiver unit and coupled to the adapter unit. The subscriber can enter dial information and service-feature-control information through the microphone of the handset of a telephone station and/or through a numeric keypad of the station. Instead of being informed of the respective line condition by tone signals, the subscriber receives this information in the form of speech from the voice output unit.
