past 10 years on the effects of hydration on voice quality in adults. Study design This is a …

The voice results in acoustic signals analyzed and synthetized at first for telecommunication
matters, and more recently investigated for medical purposes. In particular, voice signal …

Background In patients with medically refractory essential tremor, unilateral magnetic

This paper presents a revised version of the Hearing-Aid Speech Perception Index (HASPI).
The index is based on a model of the auditory periphery that incorporates changes due to …

Substantial variability and severity of dysarthric patterns across Parkinson's disease (PD)
patients may reflect distinct phenotypic differences. We aimed to compare patterns of speech …

Background: Experimental studies using qualitative or quantitative analysis have
demonstrated that the human voice progressively worsens with ageing. These studies …

Purpose Approximately 30% of adults over the age of 50 years present with altered vocal
function. Our understanding of how these changes manifest acoustically and perceptually is …

The manner and extent to which voice amplitude and frequency control mechanisms change
with age is not well understood. The related question of whether the assessment of one's …

Objectives Normative data concerning the speaking voice in the general population were
gathered with the aim to establish standard values for clinical diagnostics. Associations …
