Abstract
In a known method of recognizing a word string in a speech signal, a new specific organization of the storage locations in the memory containing the trace-back addresses is proposed. Furthermore, a step for generating the information for these storage locations is proposed which makes it possible to determine not only the word string with the best similarity, but also a specific number of further word strings of decreasing similarity. Thus, the additional computing capacity required for determining these further word strings is small relative to the computing capacity required for the remainder of the recognition process.
