Abstract
A voice recognition device for a vehicle includes: an input device receiving a command and a negative interjection uttered by a user, converting the command into a first voice signal, and converting the negative interjection into a second voice signal; a storage device storing a negative context, an interjection context, and an acoustic model; and a control device receiving the first voice signal, detecting a first start point and a first end point of the first voice signal, receiving the second voice signal after the detection of the first start point and the first end point of the first voice signal, detecting a second start point and a second end point of the second voice signal, and recognizing the second voice signal based on at least one of the negative context, the interjection context, and the acoustic model when the reception of the first voice signal and the second voice signal is completed.
