“…Examination of CPP values in the present study did not reveal any trends across voice conditions and furthermore, average CPP values did not meet the cut-off criterion indicating a dysphonic vocal quality (e.g., 4 dB; Heman-Ackah et al, 2014). These findings have significant implications for future work as CPP has been the focus of many studies investigating the relationship between speech acoustics and vocal effort following vocal loading tasks (Fujiki et al, 2017;Sundarrajan et al, 2017). The findings here would indicate that CPP is not an acoustical variable salient to the perception of vocal effort for speakers or listeners.…”

“…High levels of difficulty with IPSV tasks are associated with physical changes in the vocal folds, such as vocal fold swelling (Bastian et al, 1990), whereas improvements in ISPV ratings are predictive of vocal recovery following vocal fatigue (Hunter and Titze, 2009). Scales such as the Borg Category Ratio 10 (Borg CR10; Borg, 1982;Neely et al, 1992) and the 100 mm visual analog scale (VAS) are used to assess the instantaneous sensation of vocal effort severity at the time of the rating (e.g., Sundarrajan et al, 2017). Both are versatile scales that can be used to capture self-and listener-perceptual ratings of vocal effort, allowing for a direct comparison between ratings made by both groups (Eadie et al, 2010;Eadie and Stepp, 2013;Isetti et al, 2014;Stepp et al, 2012).…”

Excessive vocal effort is a common clinical voice symptom, yet the acoustical manifestation of vocal effort and how that is perceived by speakers and listeners has not been fully elucidated. Here, 26 vocally healthy adults increased vocal effort during the production of the utterance /ifi/, followed by self-ratings of effort on a 100 mm visual analog scale. Twenty inexperienced listeners assessed the speakers' vocal effort using the visual sort-and-rate method. Previously proposed acoustical correlates of vocal effort were calculated, including: mean sound pressure level (SPL), mean fundamental frequency (f o), relative fundamental frequency (RFF) offset cycle 10 and onset cycle 1, harmonics-to-noise ratio (HNR), cepstral peak prominence and its standard deviation (SD), and low-to-high (L/H) spectral ratio and its SD. Two separate mixed-effects regression models yielded mean SPL, L/H ratio, and HNR as significant predictors of both speaker and listener ratings of vocal effort. RFF offset cycle 10 and mean f o were significant predictors of listener ratings only. Therefore, speakers and listeners attended to similar acoustical cues when making judgments of vocal effort, but listeners also used additional time-based information. Further work is needed to determine how vocal effort manifests in the speech signal in speakers with voice disorders.

“…25 Sundarrajan, Huber, and Sivasankar stated that respiratory and laryngeal changes were followed after vocal loading thus supported the findings of present study. 26 After hydration both VRP and SRP Max-I values were increased p=7.1×10 -5 and p=1.7×10 -5 which were depicted that p>0.05. This could have been attributed with reference to perceived phonatory effort (PPE).…”

Background: Vocal loading is a phenomenon that affects the vocal folds and voice parameters. Prolonged vocal loading may cause vocal fatigue. Hydration is one of the easiest precautions to reduce the effect of vocal loading. Voice range profile is an analysis of a participant’s vocal intensity and fundamental frequency ranges. Speech range profile is a graphical display of frequency intensity interactions occurring during functional speech activity. Phonetogram software can analyse VRP and SRP.Methods: Total sixty normophonic participants (thirty male and thirty female) were included in this study. Phonetogram, version 4.40 by Tiger DRS, software used to measure the voice range profile and speech range profile. For VRP, participants were asked to produce vowel /a/ and a passage reading task was given for SRP measurement.Results: All sample recording were done at pre vocal loading task, VLT and after hydration. Parameter that were used to measure the effects were Fo-range, semitone, max-F, min-F, SPL range, max-I, min-I, area (dB). Result showed that after VLT all other parameters like Fo-range, semitone, max-F, min-F, SPL range, max-I, min-I, area (dB) in VRP and SRP were reduced except min-F VRP in male, min-I VRP and min-I SRP in both male and female participants. After hydration all other parameters were improved except max-F VRP and min-F VRP in female, max-I VRP, min-F VRP and area VRP.Conclusions: This study concluded that vocal loading has negative impact on vocal fold tissue and mass.

“…F0 range was utilized as emerging evidence suggests this measure correlates with overall vocal health 46 . There is a paucity of respiratory kinematic data following vocal exertion, but LVI and LVT appear most useful in this context 12,13 . Syllables spoken per breath group was included to allow for interpretation of lung volume findings.…”

“…voice use that compromises optimal laryngeal function) results in chronic vocal fatigue, putting an individual at risk for voice disorders. 11 Although vocal exertion may induce changes in respiratory kinematics, 12,13 vocal effort, [14][15][16] aerodynamic, [17][18][19] and acoustic voice measures, [20][21][22] virtually all work has focused on vocally healthy individuals. 23 As such, this study sought to quantify and mitigate the effects of vocal exertion in individuals reporting frequent vocal fatigue.…”

Objectives/Hypothesis: To investigate the effects of acute vocal exertion on individuals with vocal fatigue and to determine whether semi-occluded vocal tract exercises (SOVTEs) are more effective than vocal rest in mitigating acute effects.Study Design: Prospective, repeated-measures design.Methods: On consecutive days, 10 individuals (6 males, 4 females) with scores indicating vocal fatigue on the Vocal Fatigue Index completed two 10-minute vocal exertion tasks. Vocal rest or SOVTEs were interspersed in counterbalanced order between exertion tasks. Respiratory kinematic, acoustic, aerodynamic, and self-perceptual measures were collected at baseline, following vocal exertion, following SOVTE/vocal rest, and following the second exertion task.Results: Acute vocal exertion worsened phonation threshold pressure (P < .001) and vocal effort (P < .001) and reduced maximum fundamental frequency (P < .001). Speech was terminated at lower lung volumes following vocal exertion (decreased lung volume termination [LVT], P < .001). Exertion-induced changes in vocal effort and LVT were significantly reversed by both vocal rest and SOVTE. Detrimental changes in voice measures reoccurred following the second vocal exertion task. SOVTE and vocal rest protected against changes in respiratory kinematics when vocal exertion was resumed.Conclusions: Vocal exertion impacted laryngeal, respiratory, and self-perceptual measures in individuals with vocal fatigue. Both SOVTE and vocal rest partially mitigated changes in voice measures and prompted more efficient respiratory strategies that were maintained when vocal exertion resumed. These data increase our understanding of how individuals with vocal fatigue respond to vocal exertion tasks and offer preliminary guidance for optimal clinical recommendations.
