Glottography, the electrophysiological investigation of phonatory biomechanics.
Some details of phonatory biomechanics, meaning the vibratory movements of the vocal folds during phonation, are described in the introduction. Here a special emphasis is laid on the multicomponent structure of the vocal folds. Glottography is a general term used for methods to monitor the vibrations of the vocal folds. Four different types of glottography are generally recognized (fig. 2), viz...
متن کاملEffects of Consonant Type and Syllable Position within a Word on Vowel Devoicing in Japanese
"Vowel devoicing" occurs more frequently in the Tokyo dialect (standard Japanese) than in the Osaka dialect. Our previous study showed that devoicing was a) highly frequent when a stop or an affricate was at least on one side, b) less frequent when fricatives were on both sides, and c) infrequent when there was a following /h/. In order to clarify why asymmetric effect of consonantal kind on vo...
متن کاملDo French-speaking Learners Simply Omit the English /h/?
It is commonly considered that French-speaking learners of English tend to drop /h/. In such cases, a hard vowel onset is often observed, suggesting the presence of a glottal stop preceding the vowel, whereas [h] is characterised by an open glottis. First, a set of recordings of the nursery rhyme “Humpty Dumpty” pronounced by 37 French students was acoustically analysed. The H2/H1 ratio (relati...
متن کاملLaryngeal Adjustments in Japanese Voiceless Sound Production *
As part of a series of investigations on the production of sequences of unvoiced sounds in different languages, the current experiment was conducted using the combined techniques of photoelectric glottography, fiberoptic filming and laryngeal electromyography. Particular attention was paid to devoiced vowel production in various voiceless consonantal environments including geminates. The data s...
متن کاملVideostroboscopy of human vocal fold paralysis.
Previous stroboscopic studies of human vocal cord paralysis have been infrequent and have lacked documentation of the site of lesion. In order to study human laryngeal paralysis, the recurrent and superior laryngeal nerves were infiltrated unilaterally with lidocaine hydrochloride in three human volunteers. Vagal paralysis was simulated by combined (superior and recurrent) infiltration in one v...
