“…It has been generally accepted that the duration of the closed phase is greater in chest register than in falsetto (Choi et al, 1993;Henrich et al, 2005;Hirano, 1981;Roubeau, 2009;Salomão and Sundberg, 2008;Vilkman et al, 1995). Our data, based on CQ VKG calculations, indicate that this assumption is valid, but only for the cases when the posterior adduction in falsetto is the same or reduced compared to the chest register.…”

While vocal fold adduction is an important parameter in speech, relatively little has been known on the adjustment of the vocal fold adduction in singing. This study investigates the possibility of separate adjustments of cartilaginous and membranous vocal fold adduction in singing. Six female and seven male subjects, singers and non-singers, were asked to imitate an instructor in producing four phonation types: "aBducted falsetto" (FaB), "aDducted falsetto" (FaD), "aBducted Chest" (CaB), and "aDducted Chest" (CaD). The phonations were evaluated using videostroboscopy, videokymography (VKG), electroglottography (EGG), and audio recordings. All the subjects showed less posterior (cartilaginous) vocal fold adduction in phonation types FaB and CaB than in FaD and CaD, and less membranous vocal fold adduction (smaller closed quotient) in FaB and FaD than in CaB and CaD. The findings indicate that the exercises enabled the singers to separately manipulate (a) cartilaginous adduction and (b) membranous medialization of the glottis though vocal fold bulging. Membranous adduction (monitored via videokymographic closed quotient) was influenced by both membranous medialization and cartilaginous adduction. Individual control over these types of vocal fold adjustments allows singers to create different vocal timbres.

“…The literature on vocal registers abounds with descriptions of peripheral mechanisms and perceptual identification of registers (Roubeau et al 1987, Abramson et al 2004, Henrich 2006, Echternach et al 2008, Salomao and Sundberg 2008, Echternach et al 2010, Echternach et al 2011, Echternach et al 2011, Echternach et al 2012, Echternach et al 2014), but we were unable to locate sources in the literature that were related to brain mechanisms involved during register transitions. Here we report the vocal and neural responses (ERP) produced by changes in voice pitch auditory feedback that sounded to the subject as though their voice F0 was suddenly and unintentionally changing either from their modal register into another register (fry or head, referred to as “towards the register boundary”) or to a different pitch level within their modal register (referred to as “away from the register boundary”).…”

Vocal and Neural Responses to Unexpected Changes in Voice Pitch Auditory Feedback During Register Transitions

Objective/Hypothesis It is known that singers are able to control their voice to maintain a relatively constant vocal quality while transitioning between vocal registers; however, the neural mechanisms underlying this effect are not understood. It was hypothesized that greater attention to the acoustical feedback of the voice and increased control of the vocal musculature during register transitions compared to singing within a register would be represented as neurological differences in event-related potentials (ERPs). Study Design/Methods Nine singers sang musical notes at the high end of the modal register (the boundary between the modal and head/falsetto registers) and at the low end (the boundary between the modal and fry/pulse registers). While singing, the pitch of the voice auditory feedback was unexpectedly shifted either into the adjacent register (“toward” the register boundary) or within the modal register (“away from” the boundary). Singers were instructed to maintain a constant pitch and ignore any changes to their voice feedback. Results Vocal response latencies and magnitude of the accompanying N1 and P2 ERPs were greatest at the lower (modal-fry) boundary when the pitch shift carried the subjects’ voices into the fry register as opposed to remaining within the modal register. Conclusions These findings suggest that when a singer lowers the pitch of their voice such that it enters the fry register from the modal register, there is increased sensory-motor control of the voice, reflected as increased magnitude of the neural potentials to help minimize qualitative changes in the voice.
