First Claim
Patent Images
1. An apparatus for normalizing input data of an acoustic model, the apparatus comprising:
- a window extractor configured to extract windows of frame data to be input to the acoustic model from frame data of a speech to be recognized; and
a normalizer configured to normalize the frame data to be input to the acoustic model in units of the extracted windows.

16. A speech recognition apparatus comprising:
-
a preprocessor configured to; extract windows of frame data to be input to an acoustic model from frame data of a speech to be recognized, and normalize the frame data to be input to the acoustic model in units of the extracted windows; an acoustic score calculator configured to calculate acoustic scores in units of the normalized windows using the acoustic model based on a deep neural network (DNN); and an interpreter configured to; interpret the acoustic scores calculated in units of the normalized windows, and output a recognition result of the speech to be recognized based on the interpreted scores. - View Dependent Claims (17, 18, 19, 20, 21)
