Patent ID: 7047198

Claim:
An audio input device comprising: a plurality of installations to be operated; a pickup unit for picking up vocalizations of a user; a speech dictionary for storing objective recognition terms corresponding to the operations of the installations, the objective recognition term being classified with extraction weight for every installation; a remote controller operated by the user to transmit a signal wave to each of the installations to carry out remote control of the installations; and a controller connected to the installations, the pickup unit and the speech dictionary, the controller having: a calculating section for calculating respective degrees of coincidence between the user's vocalizations inputted through the pickup unit and the objective recognition terms in the speech dictionary; an extracting section for extracting the objective term having the highest degree of coincidence, from the speech dictionary; an operating section for generating an operation command to one of the installations on the ground of an extraction result transmitted from the extracting section; and an estimating section for estimating the installation at which the remote controller is pointed by the user, wherein, at the calculation of the degrees of coincidence on receipt of the user's vocalizations, the controller makes the extraction weight of the objective recognition terms concerned with the installation estimated by the estimating Section, larger than the extraction weight of the objective recognition terms concerned with the other installation.
