“…Although SS-ANOVA showed that the PD group produced lower F0 contours than the HC group, LMM analysis did not find a significant difference in the mean F0 between the two groups. This seemed to coincide with the reports in [11,12] but conflicted with [8][9][10]. To make a more reliable conclusion, the future study needs to be conducted on a larger sample.…”

“…However, [11,12] did not observe F0 mean difference between the two groups. Studies on overall speech rate of the PD group remained inconclusive, which was abnormally fast [13], abnormally slow [14] or same as control speakers [8,12,15]. In regard to intensity, reduced [9,16] or equivalent [8] intensity were found.…”

“…A raíz de aquello, se han efectuado en varias lenguas estudios fonético-acústicos que contrastan las vocales entre hablantes con EP y sujetos sin la enfermedad, tales como, inglés norteamericano (Forrest et al, 1989;Kim et al, 2009;Kim y Choi, 2017;McRae et al, 2002;Rosen et al, 2006;Tjaden et al, 2013;Tjaden y Wilding, 2004;Weismer et al, 2001;Whitfield y Goberman, 2014), coreano (Bang et al, 2013;Kang et al, 2010;Kim y Choi, 2017;Shim et al, 2012), alemán (Skodda et al, 2011(Skodda et al, , 2012(Skodda et al, , 2013, checo (Rusz, Cmejla, Růžičková, et al, 2013;Rusz, Cmejla, Tykalova, et al, 2013), chino mandarín (Gu et al, 2018;Hsu et al, 2017), español peninsular (Fernández-García et al, 2021), español cubano (Aguilera et al, 2015;Escobedo et al, 2017), italiano (Vizza et al, 2019), francés canadiense (Martel-Sauvageau y Tjaden, 2017) y portugués europeo (Proença et al, 2014). En ellos, los hablantes con EP tendieron a exhibir una menor duración de las transiciones de los formantes (Forrest et al, 1989), una menor extensión de las transiciones de los formantes (Forrest et al, 1989), una menor pendiente del segundo formante (F2) (Kim et al, 2009;Martel-Sauvageau y Tjaden, 2017;Rosen et al, 2006), un menor primer formante (F1) de /a/ (Bang et al, 2013), un mayor F1 de /i/ (Bang et al, 2013;Escobedo et al, 2017), un menor F2 de /i/ (Bang et al, 2013;…”

Esto último, constatado mediante diversos índices, tales como, el rango del F2 (Rosen et al, 2006;Rusz, Cmejla, Růžičková, et al, 2013;Shim et al, 2012), el quadrilateral vowel space area (qVSA) (Bang et al, 2013;Fernández-García et al, 2021;Hsu et al, 2017;Kang et al, 2010;McRae et al, 2002;Shim et al, 2012;Tjaden et al, 2013;Tjaden y Wilding, 2004;Vizza et al, 2019;Weismer et al, 2001), el triangular vowel space area (tVSA) (Escobedo et al, 2017;Gu et al, 2018;Kim y Choi, 2017;Proença et al, 2014;Skodda et al, 2011Skodda et al, , 2012Vizza et al, 2019), el vowel articulation index (VAI) (Escobedo et al, 2017;Gu et al, 2018;Proença et al, 2014;…”
