Individuals with Parkinson’s disease (PD) experience difficulties in various motor functions due to decreased amplitude and sensory guidance. Speech production is a motoric behavior, and difficulties with oral communication are often seen in these patients. The communication problems are primarily due to decreased airflow from the lungs, incomplete vocal fold vibration, and an insufficient rang...

BACKGROUND Lombard's effect increases the level of vocal intensity in the environment, in which noise occurs. This article presents the results of the author's own study of vocal intensity level and A-weighted sound pressure level of background noise during normal lectures. The aim of the study was to define whether above-mentioned parameters depend on acoustic properties of rooms (classrooms o...

Purpose: To investigate whether there is an association between the frequency of occurrence of vocal symptoms, the intensity of vocal deviation and laryngeal diagnosis in patients with different voice disorders. Methods: The study included 330 patients with vocal complaints. The patients were divided into five groups according to the laryngeal diagnosis: G1without laryngeal lesions; G2 -benign ...

IMPORTANCE Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral abductor vocal fold paralysis (BVFP). However, objective evidence for such a conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy. OBJECTIVE To compare voice and swallowing parameters after...

OBJECTIVE To define the effects of Lee Silverman Voice Treatment (LSVT on swallowing and voice in eight patients with idiopathic Parkinson's disease. METHODS Each patient received a modified barium swallow (MBS) in addition to voice recording before and after 1 month of LSVT. Swallowing motility disorders were defined and temporal measures of the swallow were completed from the MBS. Voice eva...

This study investigates the possibility to recover the voice strength, i.e. the sound level produced by the speaker, from the signal recorded. The dataset consists of a set of isolated vowels (720 tokens) recorded in a situation where two interlocutors interacted orally at a distance comprised between 0.40 and 6 meters, in a furnished room. For each token, voice strength is measured at the inte...

In addition to voice and articulatory disorders, swallowing disorders have been reported in as many as 95% of individuals with Parkinson’s Disease (PD). This paper addresses the effects of intensive voice treatment (Lee Silverman Voice Treatment, LSVT®) on swallowing and voice changes. After LSVT® there was an overall 51% reduction in the number of swallowing motility disorders. Voice changes i...

The general orientation and activities involved in coping with auditory hallucinations were examined in 30 schizophrenics. Age, personality dimensions, duration of illness, position, loudness and pitch of the voice and interference with activities of patients by the voice were associated with the general orientation. Systematic coping behavior was useful. Socio-economic status and degree of int...

The influence of frequency and intensity in Min dialect on maximum vocal performance has not been investigated. The purposes of this study are (1) to investigate the physiological frequency and intensity ranges of the tonal dialect of Min, and (2) to compare the physiological frequency and intensity ranges of Min to those of nontonal languages. The subjects were 40 normal Taiwanese adults. All ...

Voice is the essential medium of man's communication in social as well as professional interactions. The human voice also reflects the state of health in many medical conditions which leads voice alterations in patients. This paper presents a voice analysis approach for discriminating the People With Parkinson (PWP) on the basis of extracted voice parameters. Voice analysis basically deals...
