BACKGROUND Total Laryngectomy is a mode of treatment of patients with advanced laryngeal cancer. It affects the voice and the speech communication. OBJECTIVE To present an acoustic analysis of the new voice after total laryngectomy in Algerian hospital environment. METHODS A corpus of sounds was collected from October 2008 to September 2009 and pronounced by eight male speakers who have und...
We present an estimation of fatigue level within individual operators using voice analysis. One advantage of voice analysis is its utilization of already existing operator communications hardware (2-way radio). From the driver viewpoint it’s an unobtrusive, non-interfering, secondary task. The expected fatigue induced speech changes refer to the voice categories of intensity, rhythm, pause patt...
In an initial study it was shown that (without hormonal influences) middle-aged (premenopausal) women show a smaller frequency and intensity range and a lower fundamental frequency of the voice compared to young women. To investigate the impact of menopause on voice and nasal resonance a cross-sectional non-randomized study design was used. Vocal characteristics and nasal resonance in premenopa...
The aim of this study was to obtain acoustic correlates to vocal quality of a group of men and women with and without voice disorders, based on evaluations of a group of judges experienced in the field of vocal rehabilitation. In male subjects, perceptual evaluation of normal, hoarse and rough voice qualities was related to the following acoustic features: frequency perturbation measures (JITA,...
Parkinson's disease related speech and voice impairment have significant impact on quality of life measures. LSVT(®)LOUD voice and speech therapy (Lee Silverman Voice Therapy) has demonstrated scientific efficacy and clinical effectiveness, but musically based voice and speech therapy has been underexplored as a potentially useful method of rehabilitation. We undertook a pilot, open-label study...
background: health?related quality of life (hrql) and voice handicap index (vhi) of laryngectomies seem to be relevant regarding voice rehabilitation. the aim of this study is to assess the impact on hrql and vhi of laryngectomies, following voice rehabilitation. materials and methods: a retrospective study done at the ear, nose, and throat department of the emergency county hospital. sixty?fiv...
Communication is the method by which two persons can share any meaningful information with each other at an instant. It requires a sender who wants to communicate, message which is to be conveyed & receiver who receives this message at the receiver end. Now a days due to the advancements and technology, digital communication is receiving wide attention among researchers. Digital communication i...
This article presents a new algorithm used in order to convert the speech of one speaker so that it sounds like that of another speaker. This algorithm flexibly converts voice quality using two major technical developments. Firstly, the modification of formant frequencies and spectral intensity using piecewise linear voice conversion rules. This enables the control of spectrum parameters in det...
Objective: The effects of voice disorders vary from person to person. Occupation, work environment, life, and family reaction are variables that affect one’s perception of his/her own as an impaired voice. Voice Handicap Index (VHI) has not yet been used to compare the degree of voice disorders. Assuming that the quality of life may be different under a variety of voice disorders and that diffe...
Maintaining a small glottal opening across a large range of voice conditions is critical to normal voice production. This study investigated the effectiveness of vocal fold approximation and stiffening in regulating glottal opening and airflow during phonation, using a three-dimensional numerical model of phonation. The results showed that with increasing subglottal pressure the vocal folds wer...
