APPARATUS AND METHOD FOR RECOGNIZING NATURAL LANGUAGE DIALOGUE SPEECH

摘要

According to an aspect of the present invention, there is provided a natural language conversational speech recognition method comprising: receiving a speech signal corresponding to a user's speech; Extracting a lattice from the speech signal based on a pre-trained acoustic model and a language model; Estimating a section of the speech signal recognized as an unclear speech; Performing re-recognition of the section estimated with the indefinite speech based on the acoustic model and the language model, and combining the lattice extracted from the recognition result with the lattice extracted from the speech signal.
