ABSTRACT:
In speech recognition, a reliability measure can be determined by using various sentence hypotheses with a decreasing acoustic similarity. However, if a databank inquiry is to be derived from such a speech signal, often only individual words or even a single word from the utterance are required as data for such a databank access. Such a data, for example, the time, may be contained in the speech utterance in various ways. In accordance with the invention, a reliability measure for such a data rather than for a given word is determined, in which the same data may be constituted by various words. Thus, these various words are treated equally for determining the reliability measure.
