1. A speech recognition device, comprising: a data processing terminal, comprising: a speech input unit to receive sounds including speech and translate the received speech into digital form; a speech analyzer coupled to said speech input unit to generate voice feature parameters for the received digitized speech; and a speaker accommodation unit comprising: a first feature reference memory for storing pre-registered non-specific speaker feature information, a conversion rule generated in advance highlighting variations between previously stored specific speaker feature information and the pre-registered non-specific speaker feature information, and a feature converter for generating converted voice feature parameters received from said speech analyzer based on the conversion rule, and a speech recognition processor, comprising: a second feature reference memory for storing standard feature information corresponding to pre-registered phrases; a phrase detector to determine whether the converted voice feature parameters substantially match any pre-registered phrases in said second feature reference memory and generate phrase detection data in response thereto; and a comprehension controller coupled to said phrase detector to receive the phrase detection data, to recognize a meaning of the received speech based on the received phrase detection data, and to perform at least one of controlling an action and formulating an appropriate response responsive to the recognized meaning; wherein said data processing terminal transmits the converted voice feature parameters to said speech recognition processor which is in radio frequency communication with said data processing terminal to receive the converted voice feature parameters.
