“…Furthermore, they found gender differences in jitter and shimmer at medium loudness, which may be mainly linked to different habitual voice loudness levels [31]. Although male loudness average perturbation, while males demonstrated a significant difference in the noise-to-harmonic ratio [32]. In current study, the acoustic measures at different pitch levels were not compared statistically due to broad pitch range from 150 Hz to 310 Hz investigated but perturbation measures (%jitter and %shimmer) decreased and SNR increased gradually with higher pitch in both male and female speakers.…”

This study was designed to examine comfort levels of pitch and loudness with target matching and their effects on electroglottographic (EGG) and acoustic measures. Twelve speakers, six males and six females, were instructed to produce /a/ sustained vowel for three seconds at a comfortable pitch and loudness level without any instruction and with a target matching procedure of either a certain f0 or SPL separately with visual and auditory feedback. The range of pitch for females and males were presented by progressing up and down randomly at intervals of 5Hz from 150 Hz to 310 Hz (total 33 frequency targets) and from 85 Hz to 190 Hz (total 22 frequency targets), respectively. The loudness levels were 65, 75, 85, 95 dB (total of four intensity targets) for both males and females. Subjective estimations of comfortable levels were obtained using a 10-point equal-appearing interval rating scale following each phonation. The results showed that males and females demonstrated similar trends in loudness levels with greatest comfort at 75 dB, whereas pitch comfort ratings showed a greater variability with females having a wider range with target matching. In the comfort levels of individuals, most male and female speakers rated higher comfort at soft, rather than loud phonations. On the other hand, most male speakers perceived highest comfort levels below the comfort pitch levels they phonated under natural conditions. Higher frequency ranges, however, were perceived to be more comfortable than those of natural condition in most female speakers, although the comfortable pitch levels in spontaneous phonations were within the comfort level ranges determined by targeted phonations. When comparing acoustic (%jitter, %shimmer, SNR) and EGG measures (CQ%) between spontaneous comfortable phonations and targeted phonations produced by the same subject at similar f0 and intensity, no significant differences were observed (p>0.05). Thus, target matching procedures may be considered a compatible and alternative method to reduce the variability of comfortable pitch and loudness levels by eliciting consistent comfortable phonations.

“…Higher jitter percent (jitt%) values have been reported in HPP as compared to normal phonation (NP) in both males and females [10]. At a relatively higher F0, there is some evidence from high-speed film analysis that as F0 rises the folds tend to vibrate with an increasing symmetry of movement [24], which could be the contributing factor to an overall reduction in jitter.…”

“…This variability merely expresses the characteristic difference in the pattern of behavior of the phonatory system during two different tasks of phonation [10]. Relative average perturbation (RAP) was found to be increased during HPP in females and was reported to serve as an indicator of greater evidence of aperiodicity of the vocal folds during HPP [10]. …”

“…A high degree of variability in HNR among subjects before and after performance has been reported in singing students without any voice problems [27]. In non-singers, during HPP tasks, a reduced HNR was noted as compared to NP with a statistically significant difference in males [10]. …”

Objectives: We aimed to compare the acoustic parameters of voice between Madhya Saptak/Sthayi (MS) and Taar Saptak/Sthayi (TS) in trained Indian classical singers and between males and females. Participants and Method: Sixty-five adult trained Indian classical singers were instructed to produce MS and TS; the acoustic parameters were analyzed with the Multidimensional Voice Program. Descriptive statistics were used for analysis across tasks and gender. Two-way random-effects ANOVA was used to test the effect of gender and task. Results: Male participants had a restricted range of fundamental frequency (F0), especially at high pitches. The acoustic analysis showed a statistically significant difference for F0 measures, range of F0, jitter and pitch perturbation quotient between males and females during MS and TS. Conclusion: The use of TS, that is, high-pitch phonation, during the clinical evaluation of singers enables an understanding of their vocal behavior in the higher scales of singing.

Acoustic Voice Analysis and Maximum Phonation Time in Relation to Voice Handicap Index Score and Larynx Disease

Among larynx disease patients acoustic and MPT analyses segregated with all determined analyses between patients and control conditions except the dysfunctional group, but also to some extent between various patient groups. VHI scores correlated to jitter, shimmer and NHR scores among cancer and degenerative/inflammatory disease patients. Acoustic analyses potentially add information useful to laryngological patient studies.
