WebSep 2, 2024 · In this research, the best accuracy of 99.0% of fuzzy features can be obtained by using SVM classifier. This result has exceeded the results of other algorithms based on the same dataset (such as DWT + MFCC, deep wave net and CNN), and achieves the best performance in diagnosing cardiac diseases, as shown in Table 4. WebA DWT-based speech recognition technique is presented in this paper where MFCC is used as a feature of speech signal. These features are calculated from approximate coefficients of DWT. Comparative analyses of all the methods are carried out here.
