The present study tested whether subjects respond to unanticipated short perturbations in voice loudness feedback with compensatory responses in voice amplitude. The role of stimulus magnitude (+/- 1,3 vs 6 dB SPL), stimulus direction (up vs down), and the ongoing voice amplitude level (normal vs soft) were compared across compensations. Subjects responded to perturbations in voice loudness fee...

BACKGROUND One of the most common symptoms of speech deficits in individuals with Parkinson's disease (PD) is significantly reduced vocal loudness and pitch range. The present study investigated whether abnormal vocalizations in individuals with PD are related to sensory processing of voice auditory feedback. Perturbations in loudness or pitch of voice auditory feedback are known to elicit shor...

Using long-term-spectrum (LTAS) analysis of fluent speech, the effects of speaking in noise and of speaking with differently filtered auditory feedback as well as of voluntarily changing vocal intensity are analyzed in nine male adult singers and nonsingers. Three values in the LTAS are analyzed: the level of the main pedk near 500 HZ, of a secondary peak near 2000 Hz and at the average fundame...

Phonation threshold pressure (PTP) is frequently used for characterizing vocal fold vibration properties. However, because of the very low pressures, it is often difficult to measure PTP with acceptable accuracy. This investigation analyses an alternative pressure, the collision threshold pressure (CTP), defined as the lowest pressure required to initiate vocal fold collision. Fourteen amateur ...

There are insufficient datasets of singing files that adequately annotated. One the available includes a variety vocal techniques (n = 17) and several singers (m 20) with WAV (p 3560) is VocalSet dataset. However, although categories, including techniques, singers, tempo, loudness, in dataset, they not Therefore, this study aims to annotate make it more powerful dataset for researchers. The ann...

Lee Silverman Voice Treatment (LSVT) has well-documented treatment efficacy for individuals with hypokinetic dysarthria associated with Parkinson's disease (PD). Positive changes have been noted after treatment not only for vocal loudness but also for many other speech dimensions, including intonation (monotonicity). There have been few studies investigating the effect of LSVT on lexical tone w...

Many animals produce louder, longer or more repetitious vocalizations to compensate for increases in environmental noise. Biological costs of increased vocal effort in response to noise, including energetic costs, remain empirically undefined in many taxa, particularly in marine mammals that rely on sound for fundamental biological functions in increasingly noisy habitats. For this investigatio...

Affect influences speech, not only in the words we choose, but in the way we say them. This paper reviews the research on vocal correlates in the expression of affect and examines the ability of currently available major text-to-speech (TTS) systems to synthesize expressive speech for an emotional robot guide. Speech features discussed include pitch, duration, loudness, spectral structure, and ...
