The history of HSV is long as illustrated in the book by Woo [1]. The need for devices with more frames per second to visualize the true movement of the vocal folds led to the use of HSV setups for laryngeal evaluation in this study. Videostroboscopy (VS) is use-ful for classification and standardized scoring, but for a functional evaluation of the vocal folds during phonation, HSV affords the examiner a more representative view of the true vocal fold move-ments during the development of the voice. When using a stan-dardized protocol for classification, Olthoff et al. found that the rating “not assessable” was mentioned significantly more often with stroboscopy than with HSV [2].Woo et al. discussed the amounts of pixels for the HSV analy-sis [3]. Mendelsohn et al. compared HSV with videostroboscopy (VS) for the classification of diagnoses and treatment aspects and found both methods to be valuable [4]. Tsutsumi et al. and Oliveira et al. discussed standardization values for HSV in adults [5, 6]. However, the functional assessment in HSV is better due to the asynchronicities in VS, which is a big problem [7]. The equip-ment for HSV has become less expensive [8]. Further develop-ment of quantitative analyses of HSV is on its way, also based on HSV kymography, including software for fundamental frequency measures on HSV. Baravia et al. found that the open phases looked longer on HSV than on kymography [12]. Overall, Inwald et al. found rather big variations of many parameters based on HSV in normal persons [13]. Further development eventually, based on 3D closures of each vocal fold, gives the opportunity to measure the closure at various points of the vocal folds, which are of great interest during puberty [14]. Deep learning can facilitate the measurement of the glottis to calculate the distance between the vocal folds at a specific point [15].Stroboscopy has been an invaluable tool for the classification of diagnoses of vocal folds. The frame rate of stroboscopy setups var-ies, but the majority records at 25 frames per second. During spon-taneous speech under mean phonation, the vocal folds vibrate between 196 and 224 times per second (Hz) for women and between 107 and 132 times per second (Hz) for men, according to Oates et al. [16]. In children, the number of vibrations is much higher.In the transitory period from childhood to adulthood, the voice experiences physical changes which are not adequately docu-mented. When evaluating the movement of the vocal folds during voice breaks, stroboscopy setups do not visualize the change in frequency that the adolescent experiences as shown with electro-glottography. Mansour et al. discussed the accuracy of voice dis-orders in children [17]. There is a discussion in the literature on the duration of childhood, and a supplementary period of adoles-cence could be added. Martins et al. discussed dysphonia in child-hood from 4 to 18 years of age.
