Abstract
Bifurcated speaker specific and non-speaker specific method and apparatus is provided for enabling speech-based remote control and for recognizing the speech of an unspecified speaker at extremely high recognition rates regardless of the speaker's age, sex, or individual speech mannerisms. A device main unit is provided with a speech recognition processor for recognizing speech and taking an appropriate action, and with a user terminal containing specific speaker capture and/or preprocessing capabilities. The user terminal exchanges data with the speech recognition processor using radio transmission. The user terminal may be provided with a conversion rule generator that compares the speech of a user with previously compiled standard speech feature data and, based on this comparison result, generates a conversion rule for converting the speaker's speech feature parameters to corresponding standard speaker's feature information. The speech recognition processor, in turn, may reference the conversion rule developed in the user terminal and perform speech recognition based on the input speech feature parameters that have been converted above.
