“…The main objectives of acoustic analysis include: to contribute toward the diagnosis of neurologic diseases of different neurologic subsystems, to document progressive degeneration of neurologic disease, as well as to identify subclinical manifestations of neurologic disease 4,5,6 . The aim of the current study was to clinically and objectively describe voice in different types of dysarthrias.…”

“…noise (Carson et al, 2003;Deliyski, Shaw, & Evans, 2005a;Deliyski et al, 2005b;Hillenbrand, 1987), data acquisition environments (Deliyski, Evans, & Shaw, 2005;Scherer, Vail, & Guo, 1995;Smits, Ceuppens, & De Bodt, 2005), sampling rates (Deliyski et al, 2005b;Parsa, Jamieson, & Pretty, 2001), the microphone selection Titze & Winholtz, 1993;Winholtz & Titze, 1997), the recording hardware used (Mundt et al, 2007), population characteristics (Lei, Yang, Shen, & Gong, 2000;Mueller, 1997;Scherer et al, 1995;Xue & Fucci, 2000), and the appropriateness of stimuli employed , almost every aspect of voice acoustics has been investigated in an effort to determine the minimum requirements for accurate and repeatable recording and analytical configurations. This body of work has yielded a broad set of criteria for acoustic analysis.…”

“…Os indivíduos ficaram em pé, com os braços estendidos ao longo do corpo, o microfone do aparelho posicionado em ângulo de 90º, à distância de quatro centímetros, e em frente à boca, para evitar interferência no sinal [10][11][12][13][14] . Foi solicitado aos sujeitos que sustentassem a emissão da vogal oral aberta central /a/, em frequência e intensidade habituais, após inspiração profunda, em tempo máximo de fonação (em função da edição da amostra vocal descrita adiante), e orientados a não utilizar a reserva expiratória, com o objetivo de manter ao máximo as características do sinal irradiado pelos lábios.…”
