OBJECTIVES Relative fundamental frequency (RFF) has shown promise as an acoustic measure of voice, but the subjective and time-consuming nature of its manual estimation has made clinical translation infeasible. Here, a faster, more objective algorithm for RFF estimation is evaluated in a large and diverse sample of individuals with and without voice disorders. METHODS Acoustic recordings were...

BACKGROUND Voice disorders resulting from glottic insufficiency are a significant clinical problem in everyday phoniatric practice. One method of treatment is injection laryngoplasty. Our study aimed to assess the voice quality of patients treated with hyaluronic acid injection into the vocal fold. MATERIAL AND METHODS We studied 25 patients suffering from dysphonia, conducting laryngological...

A voice disorder database is an essential element in doing research on automatic voice disorder detection and classification. Ethnicity affects the voice characteristics of a person, and so it is necessary to develop a database by collecting the voice samples of the targeted ethnic group. This will enhance the chances of arriving at a global solution for the accurate and reliable diagnosis of v...

A well­established difference between male and female voices, at least in an Anglo­Saxon con­ text, is the greater degree of breathy voice used by women. The acoustic measure that has most commonly been used to validate this difference are the relative strengths of the first and second harmonics, H1­H2. This paper suggests that sex­specific differences in harmonic spacing comb...

PURPOSE The acoustic measure relative fundamental frequency (RFF) was investigated as a potential objective measure to track variations in vocal effort within and across individuals. METHOD Twelve speakers with healthy voices created purposeful modulations in their vocal effort during speech tasks. RFF and an aerodynamic measure of vocal effort, the ratio of sound pressure level to subglottal...

We present a study where we examined the influence of a regional accent in the perception of voice and/or speech disorders. These aspects are most of the time overshadowed in clinical context. This protocol, involving multiple sources of speech variations, is also interesting for perception theories. For the experiment, speakers with or without a Southern French accent and with or without speec...

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...

PURPOSE In this study, the authors aimed to determine the relationship between relative fundamental frequency (RFF) and listener perception of vocal effort in individuals with varying degrees of vocal hyperfunction. METHOD Thirty women diagnosed with voice disorders commonly associated with vocal hyperfunction and 10 healthy women provided speech samples that were used to obtain parameters of...

UNLABELLED Vocal alterations after thyroidectomy are generally related to laryngeal nerve injury or laryngotracheal mobility disorders caused by postoperative fibrosis or strap muscle lesion. AIM this study aims to evaluate the frequency of vocal and rima glottidis disorders after thyroidectomy. MATERIALS AND METHOD This is a prospective study based on 35 patients submitted to thyroidectomy...

Identification of voice disorders has a fundamental role in our life nowadays. Therefore, many of these diseases must be diagnosed at early stages of occurrence before they lead to a critical condition. Acoustic analysis can be used to identify voice disorders as a complementary technique with other traditional invasive methods, such as laryngoscopy. In this article, we followed an extensive st...
