The voice is a multidimensional phenomenon that must be evaluated using special tools for determining acoustic parameters. These parameters are: the pitch or voice tone, the timbre, considered as the personality of the voice that is particular of each person (determined by fundamental frequency, its harmonics and formants) and the degree of hoarseness. During sustained vibration, the vocal fold...

It is well known and demonstrated that interference spectroscopy offers capabilities to obtain passive remote optical sensing spectra of high precision and also achieves economies in size, cost, and ease of deployment compared with more conventional systems. We describe the development of a near-ultraviolet spatial heterodyne spectrometer designed for remote sensing of the global distribution o...

The research objective has been to confirm the efficiency of phonetic voice and pronunciation exercises. The results of listeners' assessment have then been compared to the objective parameters f0, shimmer and jitter, as well as to the spectra energy on the basis of LTASS. The dissimilarity index (SDDD) has been calculated to compare the spectra before and after the exercises. Voices that have ...

The paper regards the possibility of using new numerical features extracted from the phase spectrum of a speech signal for voice quality estimation in acoustic analysis for medical purposes. This novel approach does not require detection or estimation of the fundamental frequency and works on all types of speech signal: euphonic, dysphonic and aphonic as well. The experiment results presented i...

OBJECTIVES To evaluate the applicability and effectiveness of percutaneous corticosteroid injection in patients with vocal fold polyp and to describe its advantages and limitations in this group of patients. DESIGN Prospective case series. SETTING Tertiary care teaching hospital. PATIENTS Twenty-four patients with vocal fold polyp treated between March 1 and December 31, 2007. INTERVENT...

   Objectives: The present study aimed at investigating the relationship between Dysphonia Severity Index (DSI) and disease speech and voice severity of Parkinson disease (PD) patients. Method. This study was a cross-sectional ones, carried out on 45 PD patients with the age range of 50 to 75 years, who were randomly selected. The Hoehn and Yahr Scale (H.Y Scale) was employed to measure the le...
