Vocal folds of newborns are histologically different from children and adults. Reinke’s space is not clearly individualized. As shown by Titze, this structure is absolutely needed for vocal fold vibration [1]. The hypothesis for vocal production in newborn is that the air column generates itself the acoustic turbulences (vortex) from which the sound merges. Some other possible vibrators within ...

The article describes a database of emotional speech. Ten actors (5 female and 5 male) simulated the emotions, producing 10 German utterances (5 short and 5 longer sentences) which could be used in everyday communication and are interpretable in all applied emotions. The recordings were taken in an anechoic chamber with high-quality recording equipment. In addition to the sound electro-glottogr...

OBJECTIVE To describe a modified flap technique (MFT) involving the use of a false vocal fold flap for glottic reconstruction and the removal of arytenoid cartilage and to compare it with conventional frontolateral partial laryngectomy (FLPL) and laser cordectomy (LC). METHODS Twenty-eight MFT, 13 FLPL and 12 LC patients completed a standardised questionnaire for assessing aspiration, respira...

Bulbar motor deterioration due to amyotrophic lateral sclerosis (ALS) leads to the eventual impairment of speech and swallowing functions. Despite these devastating consequences, no standardized diagnostic procedure for assessing bulbar dysfunction in ALS exists and adequate objective markers of bulbar deterioration have not been identified. In this paper, we consider objective measures of spee...

The function of the posterior cricoarytenoid (PCA) muscle in phonation has not been well documented. To date, several electromyographic studies have suggested that the PCA muscle is not simply an abductor of the vocal folds, but also functions in phonation. This study used an in vivo canine laryngeal model to study the function of the PCA muscle. Subglottic pressure and electroglottographic, ph...

Previous studies have demonstrated that motor control of segmental features of speech rely to some extent on sensory feedback. Control of voice fundamental frequency (F0) has been shown to be modulated by perturbations in voice pitch feedback during various phonatory tasks and in Mandarin speech. The present study was designed to determine if voice Fo is modulated in a task-dependent manner dur...

A retrospective study is reported on endoscopic CO(2)-laser microsurgery in 69 patients with histologically verified early vocal cord cancer. A flexible nasopharyngolaryngoscope (STORZ Co) was used for preoperative assessment and occasionally for postoperative follow-up.Six years of experience with this technique have led to endoscopic cordectomy, previously not accepted as a therapeutic method...

This paper addresses two questions about voice disorders in patients with cleft lip and palate (CLP): 1. What is the actual prevalence of voice disorders in CLP and is this prevalence higher than in the non-cleft population? 2. Is there an interaction between hypernasality and phonatory dysfunction which can be assessed in terms of signal perturbation quotients? In the first study, 154 CLP pati...

According to Wyke and Kirchner (Wyke B, Kirchner J. Neurology of the larynx. In: Hinchcliffe R, Harrison D, eds. Scientific foundation of otolaryngology. London: William Heinemann Medical Books, 1976:546-66) mechanoreceptors in the subglottal mucosa play a significant role in the control of laryngeal muscle activity in response to changes of subglottal pressure during phonation. In singers this...
