“…[1][2][3] This study will focus on the activity of the IA muscle during phonation in the canine model. Electromyography (EMG) ofhuman laryngeal muscles confirms that there is an increase in the activity of the interarytenoid (lA), cricothyroid (CT), thyroarytenoid (TA), and lateral cricoarytenoid (LCA) muscles before and during phonation.…”

The interarytenoid (IA) muscle has rarely been studied in the living larynx. In this work, the role of the IA muscle in phonation was studied in three dogs by means of an in vivo phonation model. The isolated action of the IA muscle was studied by sectioning and stimulating its nerve branch. As IA activity increased, subglottic pressure increased significantly until a plateau was reached. In the absence of superior laryngeal nerve stimulation, the fundamental frequency rose with increasing IA activity. In the presence of superior laryngeal nerve stimulation, however, no significant change in fundamental frequency was observed with increasing IA activity. Measurement of adductory force demonstrated that the IA muscle adducts primarily the posterior vocal fold. In this canine model, phonation was not possible without IA stimulation, owing to a large posterior glottic chink.

“…Vocal fatigue results in muscular fatigue (Titze, 1994), which may lead to decreased muscular contraction force (Sesboue & Guincestre, 2006) and speed (Bigland-Ritchie, Johansson, Lippold & Woods, 1983). In vocal fatigue, the involvement of the thyroarytenoid (TA) muscle has been suggested (Hirano, Koike, & Joyner, 1969). A reduction in contraction force of the cricothyroid (CT) and TA muscles would restrict F o rising as contraction force of these muscles is positively correlated with F o rising (Lindestad, Fritzell & Persson, 1991).…”

There has been no published study on how voice disorders affect lexical tones in Vietnamese. In this study, we investigated a number of tonal parameters in the Northern Vietnamese dialect in 42 female teachers with muscle tension dysphonia and compared them with 30 control speakers. Speech samples included tone syllables in isolation and in a reading passage. Computerized Speech Lab 4300B was used to measure fundamental frequency. Mean tonal fundamental frequency was evaluated for group and age effects. Parameters representing pitch movement (time, size, and speed of a movement) for tone 2 and tone 5 were compared between the two groups. The results showed that there was a significant effect of muscle tension dysphonia on Vietnamese tones: mean fundamental frequency

“…Στο σημείο αυτό θα πρέπει να τονισθεί η σημασία των θυρεοαρυταινοειδών μυών του λάρυγγα, η σύσπαση των οποίων διατηρεί τον τόνο των φωνητικών χορδών. 19, 23,24 Η ένταση της φωνής εξαρτάται από την πίεση που εξασκεί ο αέρας, που βρίσκεται υπογλωττιδικά, κατά τη φάση της εκπνοής, στις γνήσιες φωνητικές χορδές καθώς και από την αντίστασή τους. Τα στοιχεία τα οποία είναι υπεύθυνα για τη χροιά της φωνής είναι οι μεταβλητού εύρους αεροφόρες κοιλότητες, που βρίσκονται πάνω ή κάτω από τη γλωττίδα.…”
