There are a number of voice analysis programs around the world. Domestic voice analysis is performed by relying heavily on specific commercial program. We intend to develop coding for voice analysis using Praat and apply it to clinical practice. This study consisted of Experiment 1 and Experiment 2. Experiment 1 was the development of automated voice analysis coding based on Praat. The coding was largely divided into a recording, an analysis, and a storage section. Experiment 2 was applied to the voice analysis of 2 male patients pre- and post-operation with this coding. The analysis parameters of this coding provided 26 parameters for vowel /a/, nine parameters for sentence analysis, and a total of 4 parameters for voice range profile analysis. In two male patients, the pitch and the intensity increased, the voice quality improved, and the sentence length decreased after surgery. The coding was well made, so the output was good in real time. The code is automated as much as possible to block manual errors and increases convenience and efficiency by generating the result sheet in real time.

Digital signal processing techniques have been used by acoustic analysis to evaluate the voice quality of the patient, due to the simplicity and non-invasive procedures for measurements.

A comparative study of the voice with sustained phonation of the vowel /a/ was made in 3 groups of male patients: (1) 20 patients receiving total laryngectomy for epidermoid carcinoma of the larynx who had acquired good voice quality after a phonatory fistuloplasty with a Herrmann voice prosthesis; (2) 20 patients undergoing total laryngectomy for epidermoid carcinoma of the larynx who had learned esophageal speech; and (3) 20 subjects with normal voices. Statistical analysis yielded significant differences in fundamental voice frequency between the 3 groups, with the patients with phonatory prostheses revealing the closest to a normal voice. For other parameters used, such as jitter, shimmer, and harmonics/noise ratio, voice quality with a phonatory prosthesis was similar to that obtained with esophageal speech.

AbstractBackgroundDisorders of voice can limit an individual's participation and impair social interaction, thus affecting overall quality of life. Perceptual and objective evaluations can provide the clinician with detailed information regarding voice disorders.MethodsThis study comprised 40 subjects aged 34–46 years, 20 of whom (10 male, 10 female) had unilateral vocal fold palsy. Data were obtained for all participants from: the Voice Handicap Index, the grade, roughness, breathiness, asthenia and strain (‘GRBAS’) scale, acoustic voice analysis, electroglottography, and voice range profiles.ResultsThe voice evaluations revealed statistically significant (p < 0.05) differences between the controls and study group, both in males and females, pre- and post-therapy.ConclusionDespite the normalisation of vocal parameters, acoustic, perceptual and self-rated assessments revealed statistically significant differences after therapy. Hence, acoustic measures, namely electroglottographic perturbation, and voice frequency and intensity range, are recommended prior to termination of therapy.

Introduction Subjective voice analysis represents a diagnostic tool in phoniatry and is a part of everyday practice if a phoniatrist has a 'trained ear'. Material and methods This clinical prospective study included a sample of 20 male patients with malignant tumors involving one vocal cord - right or left. All patients underwent otorhinolaryngological and phoniatric examinations. Subjective acoustic analysis was done when patients pronounced numbers from 1 to 10. Afterwards, voice quality was evaluated separately by two professionals using a 4-levels scale: RBH scale (roughness-breathiness-hoarseness) and GIRBAS scale (grade-instability-roughness-breathiness-asthenia-strain). Results 60% of patients presented with vocal cord immobility. Subjective acoustic analysis revealed hoarseness in 100% of patients (the most frequent value was Mod=3 intense hoarseness in 45% patients). Instability existed in 100% of patient (40% moderate, 40% intense). Strained voice existed in 100%, most frequently intense (45%). Conclusions All patients with glottic carcinoma presented with hoarseness, strain and instability of phonation. Non vibration of vocal cord significantly affects the degree of dysphonia, roughness, strain and instability. Aerodynamic changes affect voice hoarseness. RBH scale is simple, but GIRBAS scale described more psyhoacoustic phenomena most important in patients with glottic carcinoma.

<b><i>Purpose:</i></b> The purpose of this study was to establish and characterize age- and gender-specific normative data of the singing voice using the voice range profile for clinical diagnostics. Furthermore, associations between the singing voice and the socioeconomic status were examined. <b><i>Methods:</i></b> Singing voice profiles of 1,578 mostly untrained children aged between 7.0 and 16.11 years were analyzed. Participants had to reproduce sung tones at defined pitches, resulting in maximum and minimum fundamental frequency and sound pressure level (SPL). In addition, maximum phonation time (MPT) was measured. Percentile curves of frequency, SPL and MPT were estimated. To examine the associations of socioeconomic status, multivariate analyses adjusted for age and sex were performed. <b><i>Results:</i></b> In boys, the mean of the highest frequency was 750.9 Hz and lowered to 397.1 Hz with increasing age. Similarly, the minimum frequency was 194.4 Hz and lowered to 91.9 Hz. In girls, the mean maximum frequency decreased from 754.9 to 725.3 Hz. The mean minimum frequency lowered from 202.4 to 175.0 Hz. For both sexes, the mean frequency range ∆f showed a constant range of roughly 24 semitones. The MPT increased with age, for boys and girls. There was neither an effect of age nor sex on SPL<sub>min</sub> or SPL<sub>max</sub>, ranging between 52.6 and 54.1 dBA and between 86.5 and 82.8 dBA, respectively. Socioeconomic status was not associated with the above-mentioned variables. <b><i>Conclusion:</i></b> To our knowledge, this study is the first to present large normative data on the singing voice in childhood and adolescence based on a high number of measurements. In addition, we provide percentile curves for practical application in clinic and vocal pedagogy which may be applied to distinguish between normal and pathological singing voice.
