Abstract

A method and apparatus for identifying a called party suitable for use in an automated attendant system are provided. Information derived from a spoken utterance by a caller is received. Identification information associated to the caller is derived. The information derived from the spoken utterance is processed on the basis of a plurality of directory entries to identify at least one directory entry that is a potential match to the information derived from the spoken utterance. When multiple directory entries in the plurality of directory entries are potential matches to the information, a calling pattern associated to the identification information is identified and a most likely directory entry from the multiple directory entries is selected at least in part on the basis of the calling pattern. A signal conveying the selected directory entry is then released.
