Abstract: | Since MFCC was proposed, it has been widely used in feature extraction of speech signals. However, for some specific sound signals, such as baby crying signal, the direct MFCC feature extraction has a low classification and recognition rate. Through the study of MFCC feature extraction process, it is found that if each filter in the triangle filter bank is shifted upward by an ∂𝑖 (∂𝑖 ≥ 0).In addition, in the calculation of single frame MFCC, a continuous segment of sound information is reconstructed. The improved MFCC feature extraction can greatly improve the recognition rate and speed of baby crying recognition. |
