An experimental setup has been designed that makes possible a real time noise reduction and an increase of automatic word recognition rate. The applied algorithm uses a dynamical filtering method for investigated time series and has been implemented in Spartan 3 FPGA evaluation board RC10 made by Celoxica. We show that our approach increases the number of correctly recognized words in the commercial speech recognition program ViaVoice 10. |
