Comparison of Multidimensional MFCC Feature Vectors for Objective Assessment of Stuttered Disfluencies

چکیده
----------------------------------------------------------------------ABSTRACT------------------------------------------------------------------The objective approach has an advantage over the manual, which provides consistence measurement required for assessment of stuttered speech. The number of dimensions (multi dimension) plays a key role in objective assessment of stuttering. The purpose of this paper is to analyze the multidimensional MFCC features and identify which dimensional provides better accuracy. In our work 10 samples in the age group of 25 – 30 years were collected. In which 80% were used for training and remaining 20% for testing. The MFCC features of 12, 13, 26 and 39 dimensional MFCC are compared and it is found that 39 dimensional MFCC are better for assessment of stuttered speech objectively, with 84.58 % accuracy.

Automatic Detection of Syllable Repetition in Read Speech for Objective Assessment of Stuttered Disfluencies
Automatic detection of syllable repetition is one of the important parameter in assessing the stuttered speech objectively. The existing method which uses artificial neural network (ANN) requires high levels of agreement as prerequisite before attempting to train and test ANNs to separate fluent and nonfluent. We propose automatic detection method for syllable repetition in read speech for obje...

Stuttering also known as stammering is fluency disorder in which it affects the flow of speech, an involuntary repetitions, prolongation of sounds, syllables, phrase or words, and involuntary silent pause or blocks in communication. This involuntary speech disorder involves frequent and significant problems with the normal fluency and flow of speech. The number of disfluencies present in a spee...

PURPOSE The goals of the present study were to investigate whether (1) the speech disfluencies of preschool-age children are normally distributed; (2) preschool-age children who do (CWS) and do not stutter (CWNS) differ in terms of non-stuttered disfluencies; (3) age, gender, and speech-language ability affect the number and type of disfluencies children produce; and (4) parents' expressed conc...
متن کاملUsing a Uniform-Weight Grammar to Model Disfluencies in Stuttered Read Speech: A Pilot Study
Stuttering is a speech disorder characterized by certain types of speech disfluencies, such as sound repetitions, which are frequent enough to be disruptive. Speech therapists frequently use manual counts of these speech disfluencies to diagnose whether a child stutters and to track improvement through a treatment program. However, these counts are subjective, inconsistent, and prone to error. ...
متن کاملA comparison of disfluency patterns in normal and stuttered speech
While speech disfluencies are commonly found in every speaker’s speech, stuttering is a language disorder characterized by an abnormally high rate of speech aberrations, including prolongation, cessation, and repetition of speech segments [5]. However, despite the obvious differences between stuttered and normal speech, identifying the crucial qualities that identify stuttered speech remains a ...
