“…Since auditory-perceptual analysis may be inconsistent and biased due to its subjectivity [19], acoustic measures (i.e., robust and objective method for voice analysis) must be associated with the auditory-perceptual analysis to assist the understanding of phonation system mechanisms. Besides, CPPs and LTAS measures use robust algorithms, are more accurate, allow a complete analysis, are not invasive, are low cost as well as more used in studies to assess the vocal quality [16,[23][24][25][26]42,[45][46][47]. Thus, this study contributes to evidence by associating robust measures with auditory-perceptual analysis.…”

Cepstral peak prominence-smoothed (CPPs) and long-term average spectrum (LTAS) are robust measures that represent the glottal source and source-filter interactions, respectively. Until now, little has been known about how physiological events impact auditory–perceptual characteristics in the objective measures of CPPs and LTAS (alpha ratio; L1–L0). Thus, this paper aims to analyze the relationship between such acoustic measures and auditory–perceptual analysis and then determine which acoustic measure best represents voice quality. We analyzed 53 voice samples of vocally healthy participants (vocally healthy group-VHG) and 49 voice samples of participants with behavioral dysphonia (dysphonic group-DG). Each voice sample was composed of sustained vowel /a/ and connected speech. CPPs seem to be the best predictor of voice deviation in both studied populations because there was moderate to strong negative correlations with general degree, breathiness, roughness, and strain (auditory–perceptual parameters). Regarding L1–L0, this measure is related to breathiness (moderate negative correlations). Hence, L1–L0 provides information about air leak through closed glottis, assisting the phonatory efficiency analysis.

“…The cepstrum indicates to what extent f0 harmonics are individualized and how they stand out from the noise level present in the signal (87) . In general, CPP (Cepstral Peak Prominence) and CPPS (Cepstral Peak Prominence-Smoothed) values increased after the voice intervention (25,63,66,70,74) . Thus, voice interventions seem to increase the harmonic energy in the voice signal of vocally healthy individuals.…”

“…Thus, its contribution is specific, and its information is nonredundant in comparison with other procedures commonly used in vocal clinical practice. In this context, this review identified the different acoustic measures that have been used in interventions in vocally healthy individuals, including fundamental frequency (f0) measures , intensity measures (18,22,23,25,(29)(30)(31)37,39,40,(43)(44)(45)(46)49,53,(56)(57)(58)61,63,66,67,(69)(70)(71)(72)(73) , cepstral/ spectral measures (25,(39)(40)(41)66,70,(73)(74)(75)(76)(77) , perturbation and noise measures (16,18,22,23,26,27,35,36,38-46,49-52,54-56,60-62,64,65,72,78-85) , acoustic indices (16,…”

“…In the studies approached in this review, the visual analog scale (16,30,38,41,51,53,74,81,98) was the most used tool to measure voice self-perception before and after the intervention. There was great variability in the construct measured with this scale, ranging from the intensity/frequency of symptoms to the perceived effort associated with voice production.…”

Purpose to map the vocal assessment measures used to verify the effect of the intervention in vocally healthy individuals. Research strategy This is a scope review based on the research question: What vocal assessment measures are used to verify the effect of the intervention in vocally healthy individuals? The search was carried out electronically in MEDLINE (PubMed), LILACS (BVS), Scopus (Elsevier), Web of Science (Clarivate), Embase and Cochrane databases. Selection criteria The selection of studies was based on reading the titles, abstracts, keywords and full texts, applying the eligibility criteria. Data related to the publication’s bibliographic information, sample and intervention characteristics, the effects of the intervention on self-assessment, auditory-perceptual, acoustic, aerodynamic, electroglottographic measures, laryngeal examination results, among others, were extracted. The data were summarized and presented in a quantitative and descriptive way. Results 97 articles were selected, among the 979 studies mapped in this review. Acoustic analysis was the most used measure (n=70, 72.3%) to verify the effects of vocal training in the selected studies, followed by electroglottography (n= 55, 56.7%), self-assessment (n= 38, 39 .2%), aerodynamics (n= 33, 34.0%), auditory-perceptual judgment (n= 22, 22.7%) and laryngeal examination (n= 16, 16.5%). Conclusion Acoustic analysis is the measure used in most studies to verify the effect of the intervention in vocally healthy individuals.

“…55 Several recent studies have focused on the immediate effects or optimal timing of use when it comes to SOVTEs. [56][57][58] The Antonetti study concluded that the best performance or execution time, was one minute, and recommended consideration of gender when prescribing the VHFO or Lax Vox techniques, as men experienced more benefits from the VHFO, and women from the Lax Vox techniques. 56 Gilman noted significant differences in comfort between the [s],…”

Semi-Occluded Vocal Tract Exercises: Understanding the Prevalence and Purposes within the Collegiate Voice Instructor Population

Sullivan

Semi-occluded vocal tract exercises (SOVTEs) have been a topic of research and interest among voice specialists for over three decades. An SOVTE is "any exercise in which the vocal tract is made partially closed at or near the lips." When this kind of occlusion occurs there are numerous consequences that follow, but of primary interest is a beneficial change of impedance. These beneficial changes are still being studied, but efficiency in phonation, as well as a shift in the configuration of the vocal folds during phonation are two significant findings thus far. Efficiency in vocal production is paramount to a performer's vocal health. Therefore, a dissipating impedance or a hindering reactance would be undesirable. Research over the last three decades has largely addressed the degree of reactive inertance possible through such impedance and its health benefits on the speaking and singing voice. The performing arts health aspects of these benefits are increasingly relevant to professional voice users. Although research on SOVTEs has become plentiful and widely available to voice teachers, it is unknown how or if this population is digesting the current performing arts health research and implementing it within their vocal instruction. Understanding the extent to which SOVTE science is known and implemented by the current voice-teaching population could inform the current and future voice-science community on how to best alter the dissemination of upcoming research.
