Patent DE-4131387-A1 (DE)
Inventor: ZUENKLER KLAUS DIPL ING
IPC: G10L15/12
Filed: 1991-09-20
Abstract: In state-of-the-art automatic speech recognition systems, phonetically similar words (for example "zwei" and "drei", in German) are easily exchanged. In particular these recognition systems easily exchange words that differ by a single phoneme (for example "dem" and "den", in German). To solve this problem, a process is disclosed for recognizing patterns in time-varying measurement signals that makes it possible to better distinguish between such signals by means of a subsequent classification in pairs. This process combines the Viterbi decoding algorithm with the Hidden-Markov model process. The discrimination-relevant features are separately analyzed in a second step after the main classification. Different components of the feature vectors are differently weighted. On the contrary of known approaches, said weightings have a theoretical basis. The process is in particular useful for improving speech recognition systems.
