Characterizing Parkinson’s Disease Speech by Acoustic and Phonetic Features

Voice-Based Classification of Amyotrophic Lateral Sclerosis: Where Are We and Where Are We Going? A Systematic Review

“…In particular during speech articulation, reductions in the phonation rate as well as in the amplitude of the mandibular movements were identified [15]. Articulation quality measures, such as vowel space area and the formant centralization ratio, can be used, among others, as acoustic indicators of the vowel span range [28]. The reviewed studies complement the existing knowledge and reinforce the importance of voice and speech assessment as effective methods for ALS diagnosis and monitoring.…”

Deducing the severity of psychiatric symptoms from the human voice

“…that report such studies. For instance, human voice has been correlated to symptoms of mental disorders such as schizophrenia [1], depression [2,3], autism [4], Parkinsons disease [5,6], Huntington's disease [7], suicidal tendencies, etc. A wide range of personal and socially relevant traits that are also significant in psychiatric assessments are correlated with features of human voice, such as emotional state [8], dominance and attractiveness [9], threat potential [10], social status [11], personality [12], sexual orientation, level of self-consciousness etc.…”

“…A wide range of personal and socially relevant traits that are also significant in psychiatric assessments are correlated with features of human voice, such as emotional state [8], dominance and attractiveness [9], threat potential [10], social status [11], personality [12], sexual orientation, level of self-consciousness etc. Voice has also been correlated with a number of other medically relevant factors that are known to indirectly affect a person's psychological state, such as the presence of diseases [5,6], hormone levels [13], use of prescription medication [14], etc. However, most of these studies address the problem of detection of a psychiatric disorder or disease, i.e, given a population of normal and psychiatrically ill people, these studies use voice to detect the presence or absence of various illnesses in the population.…”

Desempeño fonético-acústico de vocales en hablantes del español chileno con enfermedad de Parkinson en estadios iniciales

“…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;…”
