Abstract: Speech words are recognized by first recognizing each spectral vector identified by a label (feneme), then identifying the word by matching the string of labels against phones using simplified phone machines based on label and transition probabilities and Merkov chains. In one embodiment, a detailed acoustic match word score is combined with an approximate acoustic match word score to provide a total word score for a subject word. In another embodiment, a polling word score is combined with an acoustic match word score to provide a total word score for a subject word. The acoustic models employed in the acoustic matching may correspond, alternatively, to phonetic elements or to fenemes. Fenemes represent labels generated by an acoustic processor in response to a spoken input. Apparatus and method for determining word scores according to approximate acoustic matching and for determining word scores according to a polling methodology are disclosed.

Abstract: A dishwasher has upper and lower spray arms, a telescoping spray tower and a filtering system which includes a frusto-conical screen cage, the outside of which connects to a dishwasher sump by way of a tangential channel including a drain opening therefrom. The inside of the cage connects to the inlet of a double outlet, centrifugal, recirculation pump. Particulates are filtered from recirculating dishwashing fluid on the outside of the screen as the fluid swirls around the cage in a clockwise direction. The tangential approach of the fluid sets up centrifugal forces as an aid in removing filtered particulates from the outside of the screen. A backwash spray rotates in a counterclockwise direction on the inside of the cage to keep the particulates from sticking to the screen. The pump volute is divided into two predetermined volumes rotated with respect to one another to produce two distinct cutoff points and outlets.
