Vocal responses to unanticipated perturbations in voice loudness feedback: an automatic mechanism for stabilizing voice amplitude.

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...

Vocal Responses to Perturbations in Voice Auditory Feedback in Individuals with Parkinson's Disease

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...

The Lee Silverman Voice Treatment Improves Vocal loudness in Early Persian Parkinson’s Patients: A Pilot Study

Objectives: In the early stages, most Parkinson’s patients display some degrees of voice and speech disorders. Speech disorders can negatively affect social interactions and human life, thus treatment plans for the disorders in the early stages might be further beneficial than the late stages. Therefore, we aimed to investigate on the effect of an intervention on Persian patients with early mil...

Effect of vocal loudness variation on the voice source

The physiological correlate of perceived vocal loudness is the overpressure of air under the glottis, or the subglottal pressure Psub. Variation of vocal loudness, i.e., of Psub has strong effects on the waveform of the transglottal airflow, also called the voice source. As the voice source is the primary sound itself, which after filtering by the vocal tract resonator is radiated through the l...

Compensatory responses to loudness-shifted voice feedback during production of Mandarin speech.

Previous studies have demonstrated that perturbations in voice pitch or loudness feedback lead to compensatory changes in voice F(0) or amplitude during production of sustained vowels. Responses to pitch-shifted auditory feedback have also been observed during English and Mandarin speech. The present study investigated whether Mandarin speakers would respond to amplitude-shifted feedback during...
