Abstract
An improved speech recognition system, in which transformation process parameters are generated in response to selected characteristics derived from speech inputs obtained from both carbon and linear microphones. The transformation process parameters are utilized in conjunction with selected digitized speech models to improve the speech recognition process based on the carbon microphone property of suppressing speech spectral energy for low energy invoiced sounds, and also for low energy regions of the spectrum between formant peaks for voices sounds.
