The purpose of this study was to evaluate quantitatively the parameters of the video laryngostroboscopy (VLS) and determine correlations between the VLS parameters and acoustic vocal function parameters. Digital VLS recordings, acoustic voice assessment, calculation of dysphonia severity index (DSI) and registration of voice range profile (VRP) were performed for 206 individuals: 50 healthy and...

BACKGROUND the voice of choir conductors. AIM to evaluate the vocal quality of choir conductors based on the production of a sustained vowel during singing and when speaking in order to observe auditory and acoustic differences. METHOD participants of this study were 100 choir conductors, with an equal distribution between genders. Participants were asked to produce the sustained vowel "é" ...

INTRODUCTION The aim of this study was estimation of glottis morphology and perceptive-acoustic characteristics of voice and speech in patients suffering from rheumatoid arthritis (RA). MATERIAL AND METHODS 77 patients (51 women and 15 men), 19-77 years of age (average 56,7) with recognized RA. The disease duration was from 1 month to 29 (average 9,4) years. Laryngeal, phoniatric examination ...

abstract   a cystic acoustic neurinoma almost entirely consists of a cystic component and is a well recognized subtype of acoustic schwannoma. we report a case of a 40-year- old male patient who presented with clinical features of a left cerebello-pontine angle mass lesion and ct scan findings mimicking the diagnosis of an epidermoid cyst. however intraoperative and histopathological findings w...

INTRODUCTION The voice of hearing-impaired individuals has been described extensively, and exhibits abnormalities in quality, articulation and resonance. Having an understanding of the aspects that may have an impact on voice characteristics of cochlear implant users is important for users and for professionals in this field. OBJECTIVE To verify the existence of correlation between age, time ...

During a conversation, we hear the sound of the talker as well as the intended message. Traditional models of speech perception posit that acoustic details of a talker's voice are not encoded with the message whereas more recent models propose that talker identity is automatically encoded. When shadowing speech, listeners often fail to detect a change in talker identity. The present study was d...

OBJECTIVES This study was designed to assess the impact of 2 years of operatic training on acoustic and aerodynamic characteristics of the singing voice. STUDY DESIGN This is a longitudinal study. METHODS Participants were 21 graduate students and 16 undergraduate students. They completed a variety of tasks, including laryngeal videostroboscopy, audio recording of pitch range, and singing o...
