A comparison of the perturbation analysis between PRAAT and computerize speech lab

چکیده
Programs for the analysis of pathological voice data have been presented for the last few decades. Computerized Speech Lab (CSL) has been recognized as a standard in the field of pathological voice analysis. PRAAT is a new open program which is constantly being improved almost every week. CSL gives the “Voice disorders database” which was produced by Massachusetts Eye and Ear Infirmary. In this paper, we use PRAAT program for the analysis of voice data and compare the result of PRAAT with the result of CSL. We focus on the perturbation analysis on frequencies using several parameters like jitter, standard deviation of fundamental frequencies etc.

Pitch-based speech perturbation measures using a novel GCI detection algorithm: application to pathological voice classification
Classical pitch-based perturbation measures, such as Jitter and Shimmer, are generally based on detection algorithms of pitch marks which assume the existence of a periodic pitch pattern and/or rely on the linear source-filter speech model. While these assumptions can hold for normal speech, they are generally not valid for pathological speech. The latter can indeed present strong aperiodicity,...
متن کاملCorrelation between Acoustic Parameters and Disease Severity and Duration in Patients with Multiple Sclerosis
Background: Since in multiple sclerosis (MS), changes in speech and voice quality often precede other signs and symptoms; early diagnosis of these changes is necessary. In this study, an acoustic examination of phonation subsystem was performed. Due to the progressive nature of multiple sclerosis, the aim of this study was to examine the correlation between acoustic parameters ...
متن کاملThe Relationship Between Acoustic Characteristics and Personality Dimensions in Patients With Dysphonia
Objectives: Voice is influenced by personality. However, it is still questionable which acoustic features are influenced by personality traits. This study aimed to investigate the relationship between acoustic characteristics and personality dimensions. Methods: Thirty-three participants with dysphonia and 33 participants without dysphonia were recruited to take part in this cross-sectional st...

Objective Stuttering is a developmental disorder of speech fluency with unknown causes. One of the proposed theories in this field is deficits in speech motor control that is associated with damaged control, timing, and coordination of the speech muscles. Fundamental frequency, fundamental frequency range, intensity, intensity range, and voice onset time are the most important acoustic componen...
متن کاملThe Effect of Using PRAAT Software on Pre-Intermediate EFL Learners’ Supra Segmental Features
The present study investigated the effect of using PRAAT as a free computer software package for the scientific analysis of speech in phonetics on pre-intermediate Iranian English as foreign language (EFL) learners’ supra segmental features (i.e., intonation and stress). The design of the study was a Quasi-experimental research design with a pre and post-test. In doing so...
