(14) It was suggested that the degree and timing of PCA activity were directly responsible for determining the size and temporal course of the glottal opening for voiceless segments, although the suppression of the adductors might also have to be taken into consideration for a complete description of voiceless segment production.
(15) Analysis of the data, in comparison with characteristics of phonation produced by normally hearing subjects, indicates that deafness affects primarily the time-varying characteristics of the glottal source.
(16) The glottal waveforms measured by sonic-sensing pen tracing, cursor outlining, a photocell technique, and television camera scanning are presented and compared with the conventional polar planimeter method.

(19) The results suggest that listeners base their voicing judgments of intervocalic fricatives on an assessment of the time interval in the fricative during which there is no glottal vibration.
(20) Interpretation of electroglottography (EGG) as an index of glottal contact area has been complicated by difficulty obtaining independent validation measures.
Glottis
Definition:
(n.) The opening from the pharynx into the larynx or into the trachea. See Larynx.
Example Sentences:
(1) Furthermore, an association of tiapride-corticoids was effective in treating post-anaesthetic spasm of the glottis.
(2) The values of dysphonic patients with incomplete closure of the glottis are significantly different from the other two groups.
(3) This reinforces our initial findings that it is indeed feasible to pace vocal cord abduction in bilateral recurrent laryngeal nerve paralysis with resultant return of physiologic normality to the glottis.
(4) Subglottic stenosis is a disorder characterized by narrowing of the airway below the glottis or apposing edges of the true vocal cords.
(5) It was concluded that incomplete glottal closure of the posterior parts of glottis should be regarded as normal primarily in women and that loudness should be taken into consideration when studying glottal closure and breathiness.
(6) With this procedure, the new glottis is pressed strongly to the tongue base during swallowing and aspiration is avoided.
(7) Nervous outflow to the muscles of the glottis, diaphragm, abdominal wall, tail and rear legs changed as would be expected from both the postural changes and the increases in intratracheal and intra-abdominal pressure.
(8) In the last five years of the period, the 5-year local control rate for stage I and II carcinoma of the glottis, excluding verrucous-like carcinoma, reached 90% with 10 MV X-rays combined with 60Co gamma-rays.
(9) The posterior glottis is an area of the larynx previously referred to by the terms 'posterior commissure' and 'interarytenoid'; these are poorly defined and a new definition of this unique area of the larynx is provided.
(10) The smallest laser bronchoscope is usually too large to pass through the glottis.
(11) The results indicate a firm and relatively long closure of the glottis during overtone phonation.

(17) The glottis was closely observed and photographed from above and below in three conditions: neutral, adduction, and abduction.
(18) The posterior glottis acts as a "weir" between the pharynx and larynx and so is intimately involved with diseases as they affect one area to the other.
(19) The cancer spread may superiorly involve the epilarynx, the vallecula, the base of the tongue, and the pyriform fossa; however, inferiorly, the invasion of the glottis is quite exceptional (1 percent of cases); therefore, supraglottic laryngectomy is the operation of choice.
