INTRODUCTION Dynamic MRI analysis of phonation has gathered interest in voice and speech physiology. However, there are limited data addressing the extent to which articulation is dependent on loudness. MATERIAL AND METHODS 12 professional singer subjects of different voice classifications were analysed concerning the vocal tract profiles recorded with dynamic real-time MRI with 25fps in diff...

PURPOSE To propose and verify the feasibility of a vocal program intervention in patients with presbylarynx signs with or without vocal complaints. METHOD Among 20 elder participants of the current research, 3 female patients with median age of 67 years were chosen for the pilot study. Laryngological examination, vocal recording with CAPE-V (Consensus Auditory-Perceptual Evaluation of Voice) ...

Source separation evaluation is typically a top-down process, starting with perceptual measures which capture fitness-for-purpose and followed by attempts to find physical (objective) measures that are predictive of the perceptual measures. In this paper, we take a contrasting bottom-up approach. We begin with the physical measures provided by the Blind Source Separation Evaluation Toolkit (BSS...

Background: individuals with Parkinson's disease present voice and speech alterations, especially regarding loudness and speech rate. Aim: to determine the immediate effect of modified auditory feedback: amplification, delay and masking in the voice and speech of individuals with Parkinson's disease, according to gender. Method: twenty-six subjects with Parkinson's disease (15 men and 11 women)...

The increased vocal effort associated with the Lombard reflex produces speech that is perceived as louder and judged to be more intelligible in noise than normal speech. Previous work illustrates that, on average, Lombard increases in loudness result from boosting spectral energy in a frequency band spanning the range of formants F1-F3, particularly for voiced speech. Observing additionally tha...

UNLABELLED Arthur Lessac developed a voice training approach that concentrated on three energies: structural action, tonal action, and consonant action. In Lessac-Madsen Resonant Voice Therapy (LMRVT), speech-language pathologists help patients achieve a resonant voice through structural posturing and awareness of tonal changes. However, LMRVT many not necessarily include the third component of...

According to previous investigations by Leanderson, Sundberg, & von Euler, subglottal pressure in singing is adapted to pitch and loudness. Thus, wide musical intervals and great, sudden changes of loudness were found to be associated with substantial and precise pressure changes. In this study, we will focus on the significance to subglottal pressure of smaller, but equally important effects, ...

Background: temporomandibular dysfunction is one of the most complex disorders of the body, capable of unchaining alterations in the mandibular movements which in turn can cause damage not only to speech articulation but also to the quality of voice. In the literature, the relationship between the symptomatology severity levels of this dysfunction and their influence on vocal production has bee...
