Abstract: Problems frequently occur in particular in the addition of voice enrollments (speech patterns, with which the user himself can supplement the vocabulary of the speech recognition system) to broad word lists (dynamic vocabulary). For this reason, when the speech recognition system is in an expansion mode, the speech pattern expressed by the user is associated as new voice enrollment to the existing recognizer vocabulary of the speech recognition system. Herein the assignment should however be only preliminarily in a first step. The new speech pattern is intermediate stored in a memory. The recognizer is supplied with this intermediate stored pattern for a repeated recognition process, wherein this repeated process occurs not only on the basis of the preliminarily expanded recognizer vocabulary but also on the basis of the system commands.
