In this paper, we discuss the application of mathematical formulas to guide the development of clinical interventions in voice disorders. Discussion of case examples includes fundamental frequency and intensity deviations, pitch and loudness abnormalities, laryngeal hyperand hypoadduction, and phonatory effort. The paper illustrates the interactive nature of theoretical and applied work in vocology

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.

Voice Use

The purpose of this article is to describe a structured behavior modification approach tothe reduction of voice use by clients with voice disorders. The Voice Use Reduction (VUR) Program is conceptualized as part of a comprehensive approach to the treatment of voice. The VUR Program provides guidelines for the classification of voice use situations, the assignment of voice use units to different situations, and the calculation of the maximum number of units per day and per week in a severe, moderate, and low voice use reduction program. Two case examples are described to illustrate the application of the VUR Program. The results of an evaluation of the VUR Program by 10 female students who presented with vocal nodules and applied the program also are included.

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.

Relative Fundamental Frequency

Purpose This study investigated the use of neck-skin acceleration for relative fundamental frequency (RFF) analysis. Method Forty individuals with voice disorders associated with vocal hyperfunction and 20 age- and sex-matched control participants were recorded with a subglottal neck-surface accelerometer and a microphone while producing speech stimuli appropriate for RFF. Rater reliabilities, RFF means, and RFF standard deviations derived from the accelerometer were compared with those derived from the microphone. Results RFF estimated from the accelerometer had slightly higher intrarater reliability and identical interrater reliability compared with values estimated with the microphone. Although sensor type and the Vocal Cycle × Sensor and Vocal Cycle × Sensor × Group interactions showed significant effects on RFF means, the typical RFF pattern could be derived from either sensor. For both sensors, the RFF of individuals with vocal hyperfunction was lower than that of the controls. Sensor type and its interactions did not have significant effects on RFF standard deviations. Conclusions RFF can be reliably estimated using an accelerometer, but these values cannot be compared with those collected via microphone. Future studies are needed to determine the physiological basis of RFF and examine the effect of sensors on RFF in practical voice assessment and monitoring settings.

Glottal Flow

Isshiki's (1981) proposed index of glottal flow efficiency (ac/dc ratio) and an instrument designed to measure the index (PA 500) were evaluated. Measurements of glottal flow, SPL, and fundamental frequency obtained from the PA 500 were compared with measurements obtained from more established laboratory instruments and found to be similar. Then the PA 500 was used to obtain measurements from 50 subjects without voice disorders or laryngeal pathology, 14 subjects with voice disorders and no laryngeal pathology, and 41 subjects with voice disorders and laryngeal pathology. Comparisons of ac/dc ratios revealed some significant differences among subject groups. However, when Isshiki's proposed cutoff ratio (ac/dc = 0.50) was used to determine which subjects had laryngeal pathology, 33% of the 105 subjects were misidentified. Data collected in the study provided an opportunity to evaluate Hirano's (1981) suggestion that glottal flow rates of 200 cc/s may be considered abnormal. When this flow rate was used as a cutoff score to determine which subjects had laryngeal pathology, 24% of the 105 subjects were misidentified. High variability in measurements obtained from subjects in each of the groups studied suggest that it is unlikely that ac/dc ratios or glottal flow measures, by themselves, will prove to be effective in identifying subjects with laryngeal pathology.

Abstract: Body image concerns can create challenges in a cancer survivor’s partnered relationship, and aspects of this relationship can influence how a survivor copes with body image concerns. This chapter describes both research and clinical interventions focusing on couples experiencing body image distress associated with cancer and its treatment. First, the chapter reviews observational and couple-based intervention research relevant to the problem of body image distress and the partnered relationship. Next, it offers an overview of conceptual principles relevant to couple-based clinical approaches, focusing on the key concepts of mentalization and attachment narratives. Then it provides detailed guidance on approaches for the assessment, case formulation, and management of body image distress in a relational framework through case examples. Finally, it offers a summary and introduces questions to stimulate future work in this area, including how to best optimize, expand, and disseminate couple-based interventions addressing cancer-related body image concerns.

Pitch Level

The literature has noted that speakers often perceive their own speaking pitch levels differently than listeners perceive them. However, little information is available regarding the specific characteristics of such perceptual differences. Speaking pitch level self-perception was explored in a group of 11 young adult males who served both as talkers and listeners. As a talker, each subject judged his own speaking pitch level in the process of speaking (live judgments) and during taped replay (taped judgments). The subjects' self-rankings in these two tasks and the rank order of taped voices as judged by listeners were compared to fundamental frequency rankings for the voices. The results indicated that the subjects judged their own taped voices in the same way that the listeners judged them, and the judgments corresponded to fundamental frequency rankings. During the live judgments, the subjects avoided extreme self-rankings, preferring to rank themselves closer to an average pitch level. The findings may have clinical significance in the remediation of certain voice disorders.
