Abstract: A method is described for the operation of an automatic sector information system (Yellow Pages Service) in which a user by means of a terminal (1) connected to the system transmits search parameters to the system. The system then uses these search parameters to search for subscriber data (TD) stored in a system database (3) of suppliers of a sector desired by the user, and outputs corresponding subscriber data (TD) found in the database (3) to the user. The system determines information (SI) on the location of the user and the locations of the suppliers found in the database (3) and for each supplier determines a distance measurement which corresponds to a shortest route between the user and the supplier or the time required to cover the route. The subscriber data of these suppliers are output as a function of the distance measurements of the suppliers concerned. In addition, a corresponding automatic sector information system is claimed.

Abstract: The invention relates to a speech recognition system for numeric characters, comprising a control device (33) for recognizing at least one numeric character sequence and for producing the recognized numeric characters of at least one numeric character sequence. For correcting erroneously recognized numeric characters there is proposed that the control device (33) is used for comparing a spoken second numeric character sequence with the first numeric character sequence in the case of at least one erroneously recognized numeric character of a first numeric character sequence. The control device (33) is then used for determining correlating numeric characters of a part of the first numeric character sequence, which sequence has the most matches with the numeric characters of the second numeric character sequence when the number of numeric characters of the second numeric character sequence is smaller than the number of numeric characters of the first numeric character sequence.
