An improved method of providing out-of-vocabulary word rejection is achieved by adapting an initial garbage model (,) using received incoming enrollment speech (,).

Method of out of vocabulary word rejection

An acoustic noise suppression filter including attenuation filtering with a noise suppression factor depending upon the ratio of estimated noise energy of a frame divided by estimated signal energy.
