Abstract:
A simple voice recognizer was implemented with the aim of building voice control devices by
utilizing a cascade LPC with adaptive fuzzy interface system (FIS). The accuracy of the voice
recognizer depends on the complexity of the voice commands, the number of frequency
components used, and the weights that are utilized in FIS. The quality of the voice recognizer
depends both on the time and the frequency resolution of the digitizing hardware. With a limited
set of sounds the technique discussed in this paper can be used to produce a speaker
dependent voice control system. The performance of the system improves with time due to the
adaptive nature of the system. The highly flexible backend (fuzzy interface) enables usage of
the device in noisy industrial environments.
