“…It is possible that the vocal tract can compensate for short-term changes in the vocal folds by maintaining the perceptual end product (voice) and thus the voice symptoms did not correlate. 13 It is also possible that a larger study group or differently formulated VAS symptoms are needed to find the connection between the symptoms and edema of the vocal folds resulting from the challenge test. VAS symptom's "my throat is dry and/or itchy" change showed a moderate positive correlation with the VHI total score.…”

According to the results, the laryngeal mucosal reaction during a histamine challenge test can be objectively visualized. Videolaryngostroboscopy findings, together with an increase in self-reported voice and throat symptoms, show that histamine has potential effects on vocal folds. The mucosal reaction seems to be pronounced among patients with reflux symptoms, probably reflecting the permeability features of the vocal folds.

“…An intraword vowel [a:] has commonly been used in voice analyses that apply glottal inverse filtering [e.g., [18,19,20]], as well as in some EGG studies [e.g., [21,22,23]]. A reading task to furnish connected speech material has been recommended for research purposes, while spontaneous speech has been recommended for clinical use [24].…”

Objective: This study investigated whether different electroglottographic (EGG) parameters may be used to estimate voice quality and loading related to it, and whether voice quality is related to self-estimation of voice problems and laryngeal status. The effect of sample type was also considered. Methods: EGG and acoustic signals of a sustained vowel [a:] (90 dB_{6 cm}) and text reading during noise exposure were recorded from 93 female kindergarten teachers. Analyses were made from the sustained vowel and vowel [a:] from a stressed word. Contact quotient (CQ) was calculated. Maximum velocity of increase in contact area inferred from derivative (MDEGG) was examined. Fundamental frequency was calculated from the EGG signal. From the acoustic signal sound pressure level (SPL) was computed and pressedness in voice quality was evaluated perceptually. Self-evaluation was made with Voice Activity and Participation Profile (VAPP). Indirect laryngoscopy was also performed. Results: Pressedness in voice correlated with EGG results only for the sustained vowel, and better with MDEGG than CQ values. VAPP and laryngeal evaluation did not correlate with the acoustic or EGG parameters or with perception. Conclusions: MDEGG is worth testing as an indicator of impact stress. Sustained vowel at a controlled SPL is more suitable for voice quality evaluation than a long stressed vowel from connected speech.
