OBJECTIVES/HYPOTHESIS Voice disorders have been shown to impair workplace productivity primarily by reduced efficiency while at work (presenteeism) versus increased days missed (absenteeism). Work productivity measures such as the Work Productivity and Activity Impairment (WPAI) Questionnaire or the World Health Organization Health - Work Performance Questionnaire (HPQ) can be customized to a s...

ABSTRACT: Purpose: Caring for the professional voice involves an understanding of the aspects of vocal function and the aspects affecting vocal function. The significance of the voice is especially obvious for individuals whose careers rely on speech. Clinical advice and support programs to improve voice conditions for professional voice users should be based on a foundation of empirical resear...

The paper describes the problem of cepstral speech analysis in the process of automated voice disorder probability estimation. The author proposes to derive two of the most diagnostically significant voice features: quality of harmonic structure and degree of subharmonic from cepstrum of speech signal. Traditionally, these attributes are estimated auricularly or by spectrum (or spectrogram) obs...

Personalisation of voice output communication aids (VOCAs) allows to preserve the vocal identity of people suffering from speech disorders. This can be achieved by the adaptation of HMM-based speech synthesis systems using a small amount of adaptation data. When the voice has begun to deteriorate, reconstruction is still possible in the statistical domain by correcting the parameters of the mod...

Trans men are biological females who have a male identity and sense of discomfort with their own feminine physical characteristics. The administration testosterone, hormone, for the treatment gender incongruence induces masculinization, including changing sound voice. We previously showed that continuous testosterone lowered basic frequency (F0) masculinized voice abruptly at three to six month...

BACKGROUND Voice disorders affect patients profoundly, and acoustic tools can potentially measure voice function objectively. Disordered sustained vowels exhibit wide-ranging phenomena, from nearly periodic to highly complex, aperiodic vibrations, and increased "breathiness". Modelling and surrogate data studies have shown significant nonlinear and non-Gaussian random properties in these sounds...

OBJECTIVES This study investigates differences between the self-assessment and external rating of a person's voice with regard to sex characteristics, age, and attractiveness of the voice and mean fundamental frequency (F0). STUDY DESIGN Cross-sectional study. METHODS A group of 47 participants with a balanced sex distribution was recruited and the following data were collected: videostrobo...

Speech is an integral part of communication. Speech disorder is a problem with fluency, voice, and or how a person produces a speech sound. The main focus of this study is to identify the difference between normal and disordered speech. The proposed work classifies the normal and abnormal speech. The experimental investigation elucidated MFCC and DTW with the accuracy rate of 88 % and 75% respe...
