Abstract
A system for recognizing speech receives an input speech vector and identifies a Gaussian distribution. The system determines an address from the input speech vector (610) and uses the address to retrieve a distance value for the Gaussian distribution from a table (620). The system then determines the probability of the Gaussian distribution using the distance value (630) and recognizes the input speech vector based on the determined probability (640).
