Speech recognition for the Siemens EWSD public exchange
B. Littel, J. Bauer, Siva Srikanth Reddy Janke · 2002
With the integrated voice processing system (IVPS), speech recognition capability has been made available for the EWSD public exchange. For the IVPS we designed a speaker independent, CDHMM-based IWR (isolated word recognition) system, featuring noise reduction, echo cancellation, channel adaptation, non-speech rejection and out-of-vocabulary rejection. A digit and control word vocabulary has been implemented for German, American English, French and Portuguese.
