Frequency study for the characterization of the dysphonic voices
نویسندگان
چکیده
Concerned with pathological voice assessment, this paper aims at characterizing dysphonia in the frequency domain for a better understanding of relating phenomena while most of the studies have focused only on improving classification systems for diagnosis help purposes. In this context, a GMM-based automatic classification system is applied on different frequency ranges in order to investigate which ones are relevant for dysphonia characterization. Experiment results demonstrate that the low frequencies [0-3000]Hz are more relevant for dysphonia discrimination compared with higher frequencies.

متن کاملFrequency-Based Analysis for the Characterization of the Dysphonic Voices
Since several years, many studies have focused on the objective measurement-analysis for dysphonic voice assessment, proposed as an alternative to the perceptual evaluation [5] that is extensively used by clinicians. In most cases, these studies describe classification systems, based on acoustic, physiological and/or aerodynamic parameters, in order to improve the performance and to help clinic...

OBJECTIVE To investigate the location, frequency and intensity of muscle pain in dysphonic functional/organofunctional women in comparison to women with healthy voices. METHODS Sixty women, ranging in age from 18 to 45 years, divided into two groups: Dysphonic Group (DG) - 30 women with functional or organofunctional dysphonia; Non-Dysphonic Group (NDG) - 30 women without vocal complaints, an...
متن کاملDysphonia is beautiful: A perceptual and acoustic analysis of vocal roughness
Researchers as well as speech therapists are interested in the determination of reliable acoustic cues that may be useful for the evaluation of vocal quality as well as for the diagnosis of vocal pathologies and remediation. In this way, experimental phonetics can be useful to clinical practice. This work which tries to connect phonetics and logopedic science, deals with the esthetic quality of...
