Abstract
A speech recognition system and a method executed by a speech recognition system focusing on the vocabulary of the speech recognition system and its usage during the speech recognition process is provided. A segmented vocabulary and its exploitation is provided comprising a multitude of entries wherein an entry is either identical to a legal word or a constituent of a legal word of the language, and the constituent is an arbitrary sub-component of the legal word according to the orthography. A constituent can comprise any number of characters not limited to a syllable of a legal word or a recognition unit of the speech recognition system. The vocabulary is used to recognize constituents of the vocabulary for recombination of the constituents into legal words if a constituent combination table indicates that the recognized constituents are a legal concatenation in the language.
