AbstractThe goal of this study was to determine if there are acoustical differences between pre- and post-surgical voices and to evaluate the effectiveness of Isshiki type III thyroplasty in 11 male patients with mutational voice disorders. Acoustic measures were obtained both pre- and post-operatively. A comparison of pre-and post-operative fundamental frequency (Fo), voice frequencies, and vocal intensity obtained from a sustained vowel /i/ during different phonatory tasks was made. The results from the present study demonstrated that after operation the voice frequencies were significantly decreased (p<0.05). The vocal intensity tended to reduce slightly as the voice frequency lowered. However, there were no statistically significant differences in the pre- and post-operative measures of vocal intensity (p>0.5). The preoperative high pitched voices of all the male patients were lowered up to the normal value by the type III thyroplasty.

<p><strong>Background:</strong> 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.</p><p><strong>Methods:</strong> 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.</p><p><strong>Results:</strong> 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.</p><p><strong>Conclusions:</strong> This study concluded that vocal loading has negative impact on vocal fold tissue and mass. </p>

Purpose:To analyze the correlation between acoustic measures and intensity of vocal deviation, and its discriminatory power in detecting the presence of vocal change, classifying the severity of the deviation and differencing the type of predominant voice.Methods:The sample comprised 186 patients with dysphonia. The vocal deviation from the vowel/ε/was evaluated by consensus between three speech language pathologists, using a Visual Analog Scale. We extracted the mean and standard deviation (SD) of the fundamental frequency (F0), jitter, shimmer, and Glottal-to-Noise Excitation Ratio (GNE).Results:Mean F0 was negatively correlated with the degree of roughness and positively with the degree of tension. The F0 SD was positively correlated with the overall, roughness, tension, and instability grades. The jitter and shimmer were positively correlated with all perceptual parameters. Only the GNE distinguished between healthy and dysphonic voices and rated the degree of breathiness. The shimmer separated rough voices from not rough voices. The mean F0 was helpful to determine the degree of phonatory tension and to separate rough voices from breathy and strained voices.Conclusion:There is a correlation between the acoustic and auditory perceptual measures. The shimmer, the GNE, and F0 SD can be used to detect roughness, breathing, and strain, respectively. The GNE and mean F0 are useful to classify the degree of breathiness and strain, respectively. The mean F0 distinguished between rough, breathy, and strained voices, with rough voices more severe compared to the other two.

About 20% of trans men do not achieve cisgender male frequencies (F0≤131 Hz) after gender-affirming hormone treatment (GAHT) with testosterone. The surgical procedure Isshiki thyroplasty type III (TPIII) is described to lower F0, but data on this technique in trans men are lacking. In this study, 8 trans men, unsatisfied with their voice after a minimum of 12 months of GAHT, underwent TPIII to lower F0 at the Department of Head and Neck Surgery at Ghent University Hospital. TPIII was performed by 1 surgeon using the same method each time. Pre- and postoperatively, an acoustic evaluation of the voice took place. The F0 dropped significantly from the preoperative mean of (154.60 ± 12.29) Hz to the postoperative mean of (105.37 ± 10.52) Hz ( t = 9.821, P < .001). TPIII is an effective method for lowering the F0 in trans men who are not satisfied with their voice after long-term GAHT.

Purpose Smoothed cepstral peak prominence (CPPS) and harmonics-to-noise ratio (HNR) are acoustic measures related to the periodicity, harmonicity, and noise components of an acoustic signal. To date, there is little evidence about the advantages of CPPS over HNR in voice diagnostics. Recent studies indicate that voice fundamental frequency (F0) and intensity (sound pressure level [SPL]), sample duration (DUR), vowel context (speech vs. sustained phonation), and syllable stress (SS) may influence CPPS and HNR results. The scope of this work was to investigate the effects of voice F0 and SPL, DUR, SS, and token on CPPS and HNR in dysphonic voices. Method In this retrospective study, 27 Brazilian Portuguese speakers with voice disorders were investigated. Recordings of sustained vowels (SVs) /a:/ and manually extracted vowels (EVs) /a/ from Consensus Auditory-Perceptual Evaluation of Voice sentences were acoustically analyzed with the Praat program. Results There was a highly significant effect of F0, SPL, and DUR on both CPPS and HNR ( p < .001), whereas SS and vowel context significantly affected CPPS only ( p < .05). Higher SPL, F0, and lower DUR were related to higher CPPS and HNR. SVs moderately-to-highly correlated with EVs for CPPS, whereas HNR had few and moderate correlations. In addition, CPPS and HNR highly correlated in SVs and seven EVs ( p < .05). Conclusion Speaking prosodic variations of F0, SPL, and DUR influenced both CPPS and HNR measures and led to acoustic differences between sustained and excised vowels, especially in CPPS. Vowel context, prosodic factors, and token type should be controlled for in clinical acoustic voice assessment.

The purpose of this article is to show how one urban school district dealt with a perceived need to improve its effectiveness in diagnosing and treating voice disorders. The local school district established semiannual voice clinics. Students aged 5-18 were referred, screened, and selected for the clinics if they appeared to have a chronic voice problem. The specific procedures used in setting up the voice clinics and the subsequent changes made over a 10-year period are presented.
