Method and device for pause limit values in speech recognition
First Claim
1. A method for the recognition of words and pauses from a voice signal, wherein the consecutively spoken words (Wi) and pauses (Ti) are combined as to be appertaining to a word group as soon as one of the pauses (Ti) exceeds a limit value (TG), stored references (Rj) are allocated to the voice signal of the word group, and an indication of the result of the allocation is effected after the limit value (TG) has been exceeded, comprising the steps of:
- determining the parameters corresponding to the moments of the transitions between ranges with voice and non-voice from the voice signal, andchanging the limit value (TG) in dependence on said parameters, wherein the parameters of the references (Rj) are the word beginning (RAj) and the word end (REj) of the stored references (R).

Abstract
Method and device for the recognition of words and pauses in a voice signal. The words (Wi) spoken in a row and pauses (Ti) are thereby combined as to be appertaining to a word group as soon as one of the pauses (Ti) exceeds a limit value (TG). Stored references (Rj) are allocated to the voice signal of the word group, and an indication of the result of the allocation is effected after the limit value (TG) has been exceeded. To this end, parameters corresponding to the moments of the transitions between ranges with voice and non-voice are determined from the voice signal, and the limit value (TG) is then changed in dependence on said parameters.
