Abstract

The present specification relates to a speech recognition apparatus and method capable of accurately recognizing the speech of a user in an easy and convenient manner without the user having to operate a speech recognition start button or the like. The speech recognition apparatus according to embodiments of the present specification comprises: a camera for capturing a user image; a microphone; a control unit for detecting a preset user gesture from the user image, and, if a nonlexical word is detected from the speech signal which is input through the microphone from the point in time at which the user gesture was detected, determining the speech signal detected after the detected nonlexical word as an effective speech signal; and a speech recognition unit for recognizing the effective speech signal.

Description

technical field [0001] The invention relates to a voice recognition device and method thereof. Background technique [0002] In general, speech recognition is a series of processes in which phonology, that is, verbal information is extracted from the acoustic information contained in the speech, so that the machine recognizes the above-mentioned verbal information and reacts. Conversation through speech is considered the most natural and convenient method among many information exchange media between humans and machines, but in order to converse with machines through speech, there is a limitation in converting human speech into codes that machines can process. This conversion into codes is speech recognition. Contents of the invention [0003] The problem to be solved by the invention [0004] An object of the present invention is to provide a speech recognition device and method thereof that can easily, simply and accurately recognize a user's speech without the user op...
