An ANN-based Method for Detecting Vocal Fold Pathology
There are different algorithms for vocal fold pathology diagnosis. These algorithms usually have three stages which are Feature Extraction, Feature Reduction and Classification. While the third stage implies a choice of a variety of machine learning methods, the first and second stages play a critical role in performance and accuracy of the classification system. In this paper we present initia...
متن کاملA HTK-based Method for Detecting Vocal Fold Pathology
INTRODUCTION In recent years a number of methods based on acoustic analysis were developed for vocal fold pathology detection. These methods can be categorized in two categories:a) detection based on the phonemes b) detection based on the continuous speeches. While there are many researches which belong to the first category, there are few efforts for detecting vocal fold pathology based on the...
متن کاملA novel hybrid method for vocal fold pathology diagnosis based on russian language
In this paper, first, an initial feature vector for vocal fold pathology diagnosis is proposed. Then, for optimizing the initial feature vector, a genetic algorithm is proposed. Some experiments are carried out for evaluating and comparing the classification accuracies which are obtained by the use of the different classifiers (ensemble of decision tree, discriminant analysis and K-nearest neig...
متن کاملA HMM-Based Method for Vocal Fold Pathology Diagnosis
Acoustic analysis is a proper method in vocal fold pathology diagnosis so that it can complement and in some cases replace the other invasive, based on direct vocal fold observation’s methods. There are different approaches for vocal fold pathology diagnosis. This paper presents a method based on hidden markov model which classifies speeches into two classes: the normal and the pathological. Tw...
