Expansion of the dynamic vocabulary of a voice recognition system in order to further voice rolling element

摘要

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. It is then determined on the basis of this recognition process, whether the speech pattern was recognized as element of the preliminarily expanded recognizer vocabulary or as element of the system command. If a system command was recognized, then this is carried out and the new voice enrollment is again removed from the recognizer vocabulary.
