Audio input device and method of controlling the same
First Claim
1. 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.

Abstract
An audio input device calculates respective degrees of coincidence between a user'"'"'s vocalizations and recognition terms in a voice dictionary by speech recognition and extracts a recognition term having the highest degree of coincidence from the voice dictionary. Further, the audio input device outputs a command to operate one of installations, such as radio, CD player, air conditioner, etc. The audio input device includes a remote controller for transmitting signal waves to the installations equipped with receivers to carry out remote control of the installations. In operation, the larger the installation which the remote controller is directed to has a receiving intensity of the signal wave detected byte receiver, the larger the audio input device makes an extraction weight of the recognition terms concerned with the installation, in the voice dictionary.

11. 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; means for calculating respective degrees of coincidence between the vocalizations inputted through the pickup unit and the objective recognition terms in the speech dictionary means for extracting an objective recognition term having the highest degree of coincidence, from the speech dictionary; means for operating one of the installations on the ground of an extraction result transmitted from the extracting section; a remote controller operated by the user to transmit a signal wave to each of the installations to carry out remote control of the of the installations; and means for estimating the installation at which the remote controller is pointed by the user; wherein, at the calculation on receipt of the user'"'"'s vocalizations, the extraction weight of the objective recognition terms concerned with the installation estimated by the estimating means is established larger than the extraction weight of the objective recognition terms concerned with the other installation.

12. A method of controlling an audio input device having 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, and a remote controller operated by tile user to carry out remote control of the installations by transmitting a signal wave to each of the installations, the method comprising:
-
calculating respective decrees of coincidence between the vocalizations inputted through the pickup unit and the objective recognition terms in the speech dictionary; estimating the installation at which the remote controller is pointed by the user; extracting an objective recognition term having the highest degree of coincidence, from the speech dictionary; and operating one of the installations on the ground of a result of the extracting operation; wherein, at the calculating operation, the extraction weight of the objective recognition terms concerned with the installation estimated by the estimating operation as established larger than the extraction weight of the objective recognition terms concerned with the other installation.
