Voice signals are analyzed by selecting a waveform segment and using various algorithms to arrive at parameters such as jitter, shimmer, and signal-to-noise ratio (SNR). Accurate and reliable methods for selecting a representative vowel segment have not been established.Study Design: Prospective repeated-measure experiment.Methods: We applied a moving window method by isolating consecutive, overlapping segments of the raw voice signal from onset through offset. Ten normal voice signals were analyzed using acoustic measures calculated from the moving window. The location and value of minimum perturbation/maximum SNR was compared across individuals. The moving window m...

Because structures that bear less stress can easily be deformed and involved in vibration, information on the morphology and stress distribution may provide a useful estimate of the effective depth. The results of the analyses indicate that the two muscles perform distinct roles, which allow cooperative control of the morphology and stress. When the CT muscle is activated, the tip region of the vocal folds becomes thinner and curves upward, resulting in the elevation of the stress magnitude all over the tissue to a certain degr...

Sir Felix Semon was one of the most distinguished figures in the early development of laryngology. He was an astute researcher of laryngeal pathophysiology and an active participant in laryngological scientific societies. Felix Semon was a talented doctor and was one of the most esteemed laryngologists in London for 35 years (1875–1910). Primarily, his scientific interests included complications after thyroid surgery, laryngeal cancer, tuberculosis and motor innervation of the larynx, and movement disorders of the larynx. Semon formulated the law regarding the sequence of occurrence of the laryngeal muscle paralysis—abduction before adduction. The 1...

The students’ performance voices were not perceptually clearer than their habitual voices. Perceptually clear voice was associated with significantly higher HNR (dB) and lower jitter and shimmer, suggesting that acoustic noise and perturbation contribute to perceptual judgments of vocal clarity.

This investigation attempts to describe phonation and resonance characteristics of different substyles of belting (heavy, brassy, ringy, nasal, and speechlike) and the classical style. A professional singer and voice teacher, skilled in these genres, served as the single subject. The recorded material was found representative according to a classification test performed by an expert panel. Subglottal pressure was measured as the oral pressure during the occlusion for the consonant /p/. The voice source and formant frequencies were analyzed by inverse filtering ...

Accordingly, pitch-related contributions are inseparable from those due to articulator input. In humming, articulator input is negligible. Using magnetic resonance imaging, we test the hypothesis that voice production is accompanied by pitch-related adjustments unrelated to articulatory or postural input.Study Design/Method: In this cross-sectional study, 10 healthy volunteers (five men, five women, aged 20–47 years, median 25 years), including singers (6 months to 10 years tuition, median 2 years) and non-singers, were assessed to establish the lowest and highest notes they could comfortably sustain while humming over 20 seconds.

The goal of this single group study was to quantify acoustic changes in vowels after a brief training session in vowel equalization. Fifteen young adults with amateur singing experience sang a passage and sustained isolated vowels both before and after a 15-minute training session in vowel equalization. The first two formants of the target vowels /e, i, ɑ, o, u/ were measured from microphone recordings. An analysis of variance was used to test for changes in formant values after the tr...

Therefore, many of these diseases must be diagnosed at early stages of occurrence before they lead to a critical condition. Acoustic analysis can be used to identify voice disorders as a complementary technique with other traditional invasive methods, such as laryngoscopy. In this article, we followed an extensive study in the diagnosis of voice disorders using the statistical pattern recognition techniques. Finally, we proposed a combined scheme of feature reduction methods followed by pattern recognition methods to classify voice disorders. Six classifiers are used to evaluate feature vectors obtained by principal component analysis or linear discriminant analysis (LDA) as feature reduction methods. F...

Additionally, the reliability of the difference scores between pre- and posttherapy results on the Cronbach's alpha was high on the DSP scale (0.901), but dropped to 0.506 on the interval scale. Moreover, the DSP rating scale yielded greater specificity in terms of vocal improvement posttherapy than the interval scale. The interval scale tended to mask the variation in vocal improvement among participants because of the limited choices presented.

However, most studies relied on subjective measurements only. The present study reports the results of an objective voice assessment based on a multiparameter approach in 22 adults with NF1. Aerodynamic measurements, voice range profiles, acoustic voice quality and intonation measurements, and dysphonia severity indices were obtained and compared with data from a control group, consisting of 22 healthy adults. It was found that NF1 patients show a poorer overall voice q...

Image analysis can be a valuable aid in the understanding of the morphology of the vocal tract. The application of magnetic resonance imaging to study these mechanisms has been proven to be reliable and safe. We have applied deformable models in magnetic resonance images to conduct an automatic study of the vocal tract; mainly, to evaluate the shape of the vocal tract in the articulation of some European Portuguese sounds, and then to successfully automatically segment the vocal tract's shape in new images. Thus, a point distribution model has been built from a set of magnetic resonance images acquired during artificially sustained articulations of 21 sounds, which successf...

The results correspond to the biphasic theory and may be used to help model the biomechanical and physiological properties of VF LP tissue during rehydration.

Although they are reported to produce vocal benefits in most subjects, their physiology has not yet been studied in depth. The aim of this study was to compare the mean and standard deviation of the closed quotient in exercises of lip and tongue trills with the sustained vowel /ε/ in opera singers. Ten professional classical (operatic) singers, reportedly in perfect laryngeal health, served as subjects for this study and underwent electroglottography. During the examination, the subjects were instructed to deliver the sustained vowel /ε/ and lip and tongue trills in a same preestablished frequency and intensity. The mean values and standard deviation of the cl...

It is reported to provide a quantitative acoustic index of the degree of glottal abduction and adduction in voices perceived to be breathy or pressed. In the present study, it was hypothesized that there would be abnormal reduction of higher harmonic amplitudes relative to the amplitude of the first harmonics in the subjects with vocal nodules and hence the present study was carried out.Method: One hundred twenty participants were divided into clinical group and control group. They were instructed to phonate /a/ at their most comfortable pitch and loudness. Fourier transformation of the recorded acoustic signal was first performed to create a spectrum. Amplitudes were measur...

A male singer, professionally experienced in performing in these genres, sang representative tunes, both with their original lyrics and on the syllable /pae/. In addition, he sang tones in a triad pattern ranging from the pitch Bb2 to the pitch C4 on the syllable /pae/ in pressed and neutral phonation. An expert panel was successful in classifying the samples, thus suggesting that the samples were representative of the various styles. Subglottal pressure was estimated from oral pressure during the occlusion for the consonant [p]. Flow glottograms were obtained from inverse filtering. The four lowest formant frequencies differed between the styles. T...

However, the fourth formant appears in patients who previously did not demonstrate it. The fourth formant was present in a greater proportion of male patients preoperatively than female patients, but it was universally present postoperatively and at 4 weeks in both sexes. This suggests that increasing the horizontal dimensions of the oropharynx has a nontransient effect on the higher order formants of the voice.

Phonation threshold power was measured in three sample populations of 10 excised canine larynges treated with variable posterior glottal gap, variable bilateral vocal fold elongation, and variable vocal fold lesioning. Posterior glottal gap varied from 0 to 4mm in 0.5 mm intervals. Bilateral vocal fold elongation varied from 0% to 20% in 5% intervals. Vocal fold lesion treatments included unilateral and bilateral vocal fold lesion groups. Each treatment was investigated independently in a sample population of 10 excised canine larynges. Linear regression analysis indicated that phonation threshold power was sensitive to posterior glottal gap (R2...

One reliable way to evaluate voice quality is through acoustical analysis using, for instance, the long-term average spectrum (LTAS). The aim of this study was to identify acoustic measures, particularly LTAS's, which characterize vocal aging in women without vocal complaints. For this purpose, 30 elderly and 30 young women were included in this study. All spoke standard Portuguese and none had a history of vocal and laryngeal alterations or respiratory diseases. On the basis of the reading task, in habitual and loud levels, the following parameters were assessed: the equivalent sound level (Leq), the speaking fundamental frequency (SFF) and,...

Twenty-six patients with UVFP and dysphonia (16 female and 10 male patients) were studied. Thirteen underwent surgery to improve their voice, whereas the other 13 received voice therapy. The patients were recorded at three time intervals: before the start of treatment, about 1 month after treatment has been completed, and at 3 months after treatment. They produced three types of speech material, vowels /ah/ and /oo/ and a simple sentence. The first four spectral moments (mean, standard deviation, skewness, and kurtosis) were computed from the long-term average spectrum. Severity of voice dysphonia was rated on a 11-point scale ranging fr...

The vocal sound of eight professional opera singers (six females and two males) was measured in anechoic and reverberant rooms and in a recital hall. Subjects sang in four different ways: (1) paying great attention to intonation; (2) singing as in performance, with all the emotional connection intended by the composer; (3) imagining a large auditorium; and (4) imagining a small theatre. The same song was sung by all singers in all conditions. A head and torso simulator (HATS), radiating sound from its mouth, was used for comparison in all situations. Results show that individu...

The PCA muscle had 10 times as may affected fibers as the TH muscle, with significant differences in COX− found between muscle type and fiber type (P=0.003). Almost all of this effect was the result of elevated levels of COX− in type I fibers from the PCA muscle (P=0.002) that showed a strong positive correlation with increased age. These results suggest that increased mitochondrial alterations may occur in the PCA muscle during normal aging.

Twenty-one normal females' frequencies matched on age with the cases were used as controls. The following vocal symptoms were investigated: throat clearing, deepening of the voice, loss of voice, lump in the throat, and difficulty being heard. Acoustic analysis and laryngeal videostroboscopy were performed.Results: The age range was between 19 and 38 years with a mean age of 26 years. The most common prevailing symptom was throat c...
