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. The control device (33) then substitutes the non-matching numeric characters of the second numeric character sequence for the numeric characters of the determined part of the first numeric character sequence.
