Voice recognition device
View Patent ↗A voice recognition device includes a voice recognition dictionary in which a word which is recognized as a result of voice recognition on an inputted voice is registered, a reply voice data storage unit for storing recorded voice data about words registered in the voice recognition dictionary, a dialog control unit for, when a word registered in the voice recognition dictionary is recognized, acquiring recorded voice data corresponding to the word from the reply voice data storage unit, a reproduction noise reduction unit for carrying out a process of reducing noise included in the recorded voice data, an amplitude adjusting unit for adjusting an amplitude of the recorded voice data in which the noise has been reduced to a predetermined amplitude level, and a voice reproduction unit for reproducing a voice from the amplitude-adjusted recorded voice data.
1. A voice recognition device comprising:
a voice recognition unit for carrying out voice recognition on an inputted voice;
a voice recognition dictionary in which each word which is spoken by the inputted voice and recognized as a result of the voice recognition on the inputted voice is registered;
a reply voice data storage unit for storing recorded voice data of each word spoken by the inputted voice which is registered in said voice recognition dictionary;
a dialog control unit for, when said voice recognition unit voice recognizes a word which is registered in said voice recognition dictionary, acquiring recorded voice data corresponding to the word from said reply voice data storage unit;
a reproduction noise reduction unit for carrying out a process of reducing noise included in the recorded voice data which are acquired from said reply voice data storage unit by said dialog control unit;
an amplitude adjusting unit for adjusting an amplitude of said recorded voice data in which the noise has been reduced by said reproduction noise reduction unit to a predetermined sound amplitude level; and
a voice reproduction unit for reproducing a voice from the recorded voice data for reproduction which are outputted from said amplitude adjusting unit.
2. The voice recognition device according to claim 1 , wherein said voice recognition device includes a recognition noise reduction unit for carrying out a process of reducing noise included in the inputted voice inputted to said voice recognition unit.
3. A voice recognition device comprising:
a voice recognition unit for carrying out voice recognition on an inputted voice;
a voice recognition dictionary in which each word which is spoken by the inputted voice and recognized as a result of the voice recognition on the inputted voice is registered;
a reply voice data storage unit for storing recorded voice data of each word spoken by the inputted voice which is registered in said voice recognition dictionary;
a dialog control unit for, when said voice recognition unit voice recognizes a word which is registered in said voice recognition dictionary, acquiring recorded voice data corresponding to the word from said reply voice data storage unit;
a reproduction noise reduction unit for carrying out a process of reducing noise included in the inputted voice which is stored in said reply voice data storage unit as said recorded voice data;
an amplitude adjusting unit for adjusting an amplitude of said recorded voice data which are acquired from said reply voice data storage unit by said dialog control unit to a predetermined sound amplitude level; and
a voice reproduction unit for reproducing a voice from the recorded voice data for reproduction which are outputted from said amplitude adjusting unit.
4. The voice recognition device according to claim 3 , wherein said voice recognition device includes a recognition noise reduction unit for carrying out a process of reducing noise included in the inputted voice inputted to said voice recognition unit.
