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.

Abstract: In the case of vary large vocabulary, such as for example a list with all cities in Germany, there is the problem, that the addition of other words, which are activated parallel to this list during recognition, leads to a higher danger of a mix-up. If the recognition result cannot be associated with sufficient confidence with an element from a vocabulary list, then the user of the system is presented with the recognition result for confirmation thereof. Prior to the presentation of the system user with the recognition result a temporary vocabulary is formed, in which first that element is removed from the vocabulary list, of which the correct recognition is to be confirmed by the user. The recognizer processes this speech input on the basis of the temporary vocabulary as well as on the basis of the system commands and selects therefrom as recognition result at least one element.

Abstract: Due to the large vocabulary to be recognized, it is presently not possible in many commercially available speech recognition systems to identify, with the desired good recognition results, commands in parallel to the list elements (mostly recorded as dynamic vocabulary). It is now proposed that the speech pattern supplied to the speech recognition system by the user is intermediate stored. Parallel thereto, the at least one element selected from the list by the speech recognizer is merged in a first recognition step with the system command to form a temporary recognizer vocabulary. After the production of this temporary recognizer vocabulary, subsequently the intermediate stored speech input is newly submitted to the recognizer, wherein this now forms the basis of this temporary recognizer vocabulary.
