Abstract: The present invention relates to a speech recognition apparatus and system for recognizing speech and converting the speech into text, and displaying an input state thereof in real-time for correction. In the speech recognition apparatus, speech input from a speech input unit is converted into text in units of words to display the converted text in real time on a first display window, and words displayed on the first display window are combined to generate a sentence such that the generated sentence is displayed on a second display window in real time. Therefore, a process through which what kind of sentence is formed by a combination of what kind of words may be intuitively confirmed so that text generated through speech recognition may be easily corrected.

Abstract: The present invention relates to a multi-speaker speech recognition correction system for determining a speaker of an utterance with a simple method and easily correcting speech-recognized text during speech recognition for a plurality of speakers. According to the present invention, when speech signals are input to a multi-speaker speech recognition system from a plurality of microphones which are each provided to a corresponding one of a plurality of speakers, the multi-speaker speech recognition correction system may detect a speech session from a time point at which input of each of the speech signals is started to a time point at which the input of the speech signal is stopped, and a speech recognizer may convert only the detected speech sessions into text so that a speaker of an utterance can be identified by a simple method and speech recognition can be carried out at a low cost.
