The aim of this study is to assess the consequences of thyroid surgery on the voice of patients, in order to identify various perturbations which this surgery may provoke, and also to reveal possible compensatory strategies or readjustments that the patient may develop. The assessment was based on the analysis of acoustic signals, from which a large amount of cues related to voice quality was e...

Right or bilateral anterior temporal damage can impair face recognition, but whether this is an associative variant of prosopagnosia or part of a multimodal disorder of person recognition is an unsettled question, with implications for cognitive and neuroanatomic models of person recognition. We assessed voice perception and short-term recognition of recently heard voices in 10 subjects with im...

Parkinson’s disease (PD) is a neuro-degenerative disorder that commonly affects bodily movements and speech. To date, clinical management for speech issues with PD has focused primarily on “one-on-one” individual therapy to remediate the severely reduced volume of speech. The subjective aspects of speech, particularly the perception of voice-related quality of life, may improve through social i...

BACKGROUND Spasmodic dysphonia (SD) is a focal dystonia of the larynx. Although individuals with SD have variable degrees of difficulty in everyday communication and speaking, many report significant impairments. The impact of SD on the quality of life of people with the disorder has not been well measured. OBJECTIVES To assess the impact of SD using a voice-specific, validated outcomes instr...

Introduction: Essential vocal tremor (EVT) is vocal tremor occurring in an individual diagnosed with essential tremor and is an action induced tremor that occurs during speech production. It causes fewer communication attempts, difficulty initiating and maintaining phonation, effortful speaking avoidance of social events trouble sustaining relationship leading to impair quality of life for such...

BACKGROUND AND OBJECTIVE Carnatic singing is a classical South Indian style of music that involves rigorous training to produce an "open throated" loud, predominantly low-pitched singing, embedded with vocal nuances in higher pitches. Voice problems in singers are not uncommon. The objective was to report the nature of voice problems and apply a routine protocol to assess the voice. METHODS F...

Spasmodic (spastic) dysphonia (SD) is considered by some to be a neurologic syndrome and by others a symptom complex of multiple etiologies, neurologic and psychogenic. A case of a 26-year-old female psychiatric nurse with psychogenic SD (PSD) is presented. The dysphonia was alleviated within one session of voice therapy. Psychogenic etiology was established by the author, based on three diagno...

Pitch period and amplitude perturbations are widely used parameters to discriminate normal and voice disorder speech. Instantaneous pitch period and amplitude of glottal vibrations directly from the speech waveform may not give an accurate estimation of jitter and shimmer. In this paper, the significance of epochs (glottal closure instants) and strength of excitation (SoE) derived from the zero...

OBJECTIVE Our ability to speak is complex, and the role of the central nervous system in controlling speech production is often overlooked in the field of otolaryngology. In this brief review, we present an integrated overview of speech production with a focus on the role of central nervous system. The role of central control of voice production is then further discussed in relation to the pote...

PURPOSE Integrative review of the scientific literature about the behavioral characteristics of dysphonic children discussing profiled and their etiologic relationship with the voice disorder, seeking to define recommendations on the importance of analyzing the behavior of children in voice assessment. RESEARCH STRATEGY Integrative review of articles published in the last 12 years, the Virtua...
