A large number of people around the world struggle daily to become free of their addiction to illegal psychoactive substances. In order to create an atmosphere of improved supervision, established communication and improved quality of life for drug addicts, centers have been set up to provide methadone as a substitute.
The aim of the research was to assess the vocal features of drug addicts on methadone therapy via subjective and objective parameters, to ascertain if vocal damage has occurred and to determine whether subjective and objective acoustic vocal parameters are related, and how.
The research included 34 adults of both genders who were undergoing methadone treatment. A subjective vocal evaluation assessed voice pitch and clarity, while the subjective acoustic analysis utilized the Roughness-Breathiness-Hoarseness scale of roughness-breathiness-hoarseness. Objective acoustic analysis was conducted after recording and analyzing an uninterrupted vocal /a/ of at least three seconds duration, using the "GllotisController" software.
The subjective acoustic analysis using the Roughness-Breathiness-Hoarseness scale showed pathological values in 52.9% male and 47% female participants. The average values of the roughness-breathiness-hoarseness for the entire sample were 0.91, 0.38 and 0.50, respectively. Lower roughness was associated with a higher fundamental frequency (f) and lower jitter and shimmer values (p<0.05). There was a statistically significant correlation between breathiness, jitter (p<0.01) and shimmer (p<0.05), and between hoarseness and jitter (p<0.01).
A statistically significant correlation was found between the two subjective vocal assessments, voice clarity and pitch, and Roughness-Breathiness-Hoarseness scale, and the parameters of the objective acoustic vocal assessment.
全球有大量的人每天都在努力摆脱对非法精神活性物质的依赖。为了营造加强监管、建立沟通和改善吸毒者生活质量的氛围，设立了中心，提供美沙酮作为替代物。
本研究旨在通过主观和客观参数评估接受美沙酮治疗的吸毒者的嗓音特征，确定是否发生了嗓音损伤，并确定主观和客观声学嗓音参数之间的关系及其方式。
该研究纳入了 34 名正在接受美沙酮治疗的成年人，包括男性和女性。主观嗓音评估评估了嗓音音高和清晰度，而主观声学分析则使用了粗糙度-呼吸度-糙度的粗糙度-呼吸度-糙度量表。在录制和分析至少 3 秒的不间断/a/音后，使用“GllotisController”软件进行客观声学分析。
使用粗糙度-呼吸度-糙度量表进行的主观声学分析显示，52.9%的男性和 47%的女性参与者存在病理性值。整个样本的粗糙度-呼吸度-糙度平均值分别为 0.91、0.38 和 0.50。粗糙度越低，基频（f）越高，抖动和闪烁值越低（p<0.05）。呼吸度、抖动（p<0.01）和闪烁（p<0.05）之间以及糙度和抖动（p<0.01）之间存在统计学显著相关性。
在主观嗓音评估的两个参数，即清晰度和音高，以及粗糙度-呼吸度-糙度量表，以及客观声学嗓音评估的参数之间，发现了统计学上显著的相关性。
