In Memoriam: Richard MillerEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
On May 05, 2009, Dr. Richard Miller died in his sleep. What a loss to the singing world. Richard was a well-rounded astounding voice pedagogue. He worked hard at achieving this stature. In early days, he took a sabbatical and went to Europe with the purpose of visiting other leading voice teachers. The result of his studies was his book, The English, French, German and Italian Techniques of Singing, the first of its kind that details the pedagogy of the national schools. His knowledge of anatomy served him well in writing the description of various national schools as was evident in the anatomical terminology. In addition,...

Perceiving the Effects of Ethanol Intoxication on VoiceEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: Many conditions operate to degrade the quality of the human voice. Alcohol intoxication is one of them. In this project, the objectives were to examine the ability of human listeners to accurately estimate both the presence and severity of intoxication from two types of speech samples. A review of available data suggests that, although listeners can often identify individuals who are intoxicated simply by hearing samples of their voice, they are less efficient at accurately determining the severity of this condition. A number of aural-perceptual studies were carried out to test these relationships. Populations of ...

Formant Characteristics of Vowels Produced by Mandarin Esophageal SpeakersEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: With the use of the pharyngoesophageal (PE) segment as the neoglottis in esophageal speakers, their voice quality becomes significantly different from that of laryngeal speakers. The present study investigated the characteristics of the vocal tract resonance in Mandarin esophageal speakers. The first three formant frequencies of vowels /а, ɛ, i, ɔ, u, y/ produced by seven superior esophageal and seven laryngeal speakers of Mandarin were obtained. For each formant, the formant frequencies measured from the medial 80% of the vowel portion were averaged, and data obtained from esophageal speakers were compared wit...

Electroglottographic and Perceptual Evaluation of Tracheoesophageal SpeechEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study is a cross-sectional study of the largest cohort of TO speakers treated by a single surgeon. A second group of normal laryngeal speakers served as a control group. EGG analysis of both groups using connected speech and sustained vowels was performed. Two trained expert raters undertook perceptual evaluation using two accepted scales. EGG measures were then analyzed for correlation with treatment variables. A separate correlation analysis was performed to identify EGG measures that may be associated with perceptual dimensions. Our data from EGG analysis are similar to data obtained from conventional acoustic sign...

The Innervation of the Posterior Cricoarytenoid Muscle: Exploring Clinical PossibilitiesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: Manipulation of the nerve supply to the posterior cricoarytenoid (PCA) muscle has potential for ameliorating the symptoms of some neurologic conditions such as abductor spasmodic dysphonia. The anatomy of the nerve supply to the PCA is better understood than in previous eras, but the anatomical understanding has not translated to clinical application yet. Microscopic dissection allowed the identification and measurement of the branches from the recurrent laryngeal nerves (RLNs) to the PCA in 43 human cadaver larynges. The cricothyroid (CT) joint was the primary landmark for measurement. Other structural measuremen...

Muscle Tension Dysphonia in Vietnamese Female TeachersEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: There has been no published research on muscle tension dysphonia (MTD) in speakers who use a tonal language. Using a sample of 47 Northern Vietnamese female primary school teachers with MTD, we aimed to discover whether professional voice users of tonal languages presented with the same symptoms of MTD as speakers of nontonal languages and whether they presented with additional symptoms as a result of speaking a tonal language. The vocal characteristics were assessed by use of a questionnaire and expert perceptual evaluation. Laryngeal features were assessed by photolaryngoscopy. The results showed that MTD was as...

Variability of Normal Vocal Fold Dynamics for Different Vocal Loading in One Healthy Subject Investigated by PhonovibrogramsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: We investigate the potential of high-speed digital imaging technique (HSI) and the phonovibrogram (PVG) analysis in normal vocal fold dynamics by studying the effects of continuous voice use (vocal loading) during the workday. One healthy subject was recorded at sustained phonation 13 times within 2 consecutive days in the morning before and in the afternoon after vocal loading, respectively. Vocal fold dynamics were extracted and visualized by PVGs. The characteristic PVG patterns were extracted representing vocal fold vibration types. The parameter values were then analyzed by statistics regarding vocal load, le...

Reliable Time to Estimate Subglottal PressureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: Measuring subglottal pressure (Ps) with complete interruption can be problematic due to unsteady plateaus in supraglottal pressure data traces during balloon valve interruption. Subjectively determining when the graph plateaus neglect the effects of laryngeal, auditory, and other physical reflexes may alter patient effort and glottal configuration. If the Ps estimation was made at a consistent time before the onset of reflexes, the recorded pressure would not be dependent on subjective analysis by a clinician, and intrasubject data would be more precise. Previously collected data using the airflow interruption sys...

Validation of a Glottographic Measure of Vocal AttackEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This report describes the experimental validation of this measure, whereby the SP and EGG signals were recorded synchronously with high-speed videoendoscopy, from which a digital kymogram was generated. It is shown that, after appropriate signal processing, the intersignal time delay provides a potentially useful measure that varies with vocal attack characteristics. The proposed method calls for no invasive procedures and relies on signals that are routinely obtained in most clinical settings. Unlike acoustic “rise time” measures of voice onset, the glottographic measure involves no operator intervention, requires no ...

Laryngeal-Level Amplitude Modulation in VibratoEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: The goal of this investigation was to test a new methodology for measuring amplitude modulation (AM) at the level of the vocal folds during vibrato in trained singers, because previous research has suggested that AM arises in large part as an acoustic epiphenomenon through an interaction of the harmonics in the laryngeal source with the resonances of the vocal tract as the fundamental frequency oscillates. A within-subjects model was used to compare vocal activity across three pitch and three loudness conditions. Seventeen female singers with a range of training and experience were recorded with a microphone and a...

The Shear Modulus of the Human Vocal Fold in a Transverse DirectionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: The aim of this study was to measure the shear modulus of the vocal fold in a human hemilarynx, such that the data can be related to direction of applied stress and anatomical context. Dynamic spring rate data were collected using a modified linear skin rheometer using human hemilarynges, and converted to estimated shear modulus via application of a simple shear model. The measurement probe was attached to the epithelial layer of the vocal fold cover using suction. A sinusoidal force of 3g was applied to the epithelium, and the resultant displacement logged at a rate of 1kHz. Force measurement accuracy was 20μg a...

Viscoelastic Measurements of Vocal Folds Using the Linear Skin RheometerEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary: As the number of interventions for vocal fold scar grows and with the advancement of mathematical modeling, greater accuracy and precision in the measurement of vocal fold pliability will become essential. Although indirect pliability measures have been used successfully, direct measurement of tissue pliability is essential. Indirect measurement with parallel plate technology has limitations; it requires the tissue to be removed from the surrounding framework, allows no site specificity, and offers no future for in vivo use in animals or humans. We tested the linear skin rheometer (LSR) in the evaluation of vocal ...
