-
conducting a partial speech recognition on the first expression part using a Hidden-Markov-Model, wherein the remaining expression parts are covered by fill data, the partial speech recognition using a first vocabulary having a list of search terms for the first expression part, the partial speech recognition selecting N best fitting hits for the first expression part from the list of search terms; and conducting a complete speech recognition after the partial speech recognition, the complete speech recognition being performed for the first and the remaining expression parts, the complete speech recognition being conducted using a second vocabulary comprising a list of search term combinations depending on the N best fitting hits for the first expression part. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
