This study aimed to determine the influence of native language on the auditory-perceptual assessment of voice, as completed by Brazilian and Anglo-Canadian listeners using Brazilian vocal samples and the grade, roughness, breathiness, asthenia, strain (GRBAS) scale.
This is an analytical, observational, comparative, and transversal study conducted at the Speech Language Pathology Department of the Federal University of Minas Gerais in Brazil, and at the Communication Sciences and Disorders Department of the University of Alberta in Canada.
The GRBAS scale, connected speech, and a sustained vowel were used in this study. The vocal samples were drawn randomly from a database of recorded speech of Brazilian adults, some with healthy voices and some with voice disorders. The database is housed at the Federal University of Minas Gerais. Forty-six samples of connected speech (recitation of days of the week), produced by 35 women and 11 men, and 46 samples of the sustained vowel /a/, produced by 37 women and 9 men, were used in this study. The listeners were divided into two groups of three speech therapists, according to nationality: Brazilian or Anglo-Canadian. The groups were matched according to the years of professional experience of participants. The weighted kappa was used to calculate the intra- and inter-rater agreements, with 95% confidence intervals, respectively.
An analysis of the intra-rater agreement showed that Brazilians and Canadians had similar results in auditory-perceptual evaluation of sustained vowel and connected speech. The results of the inter-rater agreement of connected speech and sustained vowel indicated that Brazilians and Canadians had, respectively, moderate agreement on the overall severity (0.57 and 0.50), breathiness (0.45 and 0.45), and asthenia (0.50 and 0.46); poor correlation on roughness (0.19 and 0.007); and weak correlation on strain to connected speech (0.22), and moderate correlation to sustained vowel (0.50).
In general, auditory-perceptual evaluation is not influenced by the native language on most dimensions of the perceptual parameters of the GRBAS scale.
本研究旨在确定母语对语音听觉感知评估的影响，该评估由巴西和英裔加拿大听众使用巴西语音样本并采用等级、粗糙度、气息声、无力感、紧张度（GRBAS）量表完成。
这是一项在巴西米纳斯吉拉斯联邦大学言语语言病理学系和加拿大阿尔伯塔大学通信科学与障碍学系进行的分析性、观察性、对比性横断面研究。
本研究使用了GRBAS量表、连贯言语和一个持续元音。语音样本从巴西成年人录音语音数据库中随机抽取，其中一些人声音健康，一些人存在语音障碍。该数据库存于米纳斯吉拉斯联邦大学。本研究使用了由35名女性和11名男性产生的46个连贯言语样本（背诵一周中的日子），以及由37名女性和9名男性产生的46个持续元音/a/样本。听众根据国籍分为两组，每组由三名言语治疗师组成：巴西组或英裔加拿大组。两组根据参与者的专业经验年限进行匹配。加权kappa用于分别计算评分者内和评分者间的一致性，并给出95%置信区间。
评分者内一致性分析表明，巴西人和加拿大人在持续元音和连贯言语的听觉感知评估中结果相似。连贯言语和持续元音的评分者间一致性结果表明，巴西人和加拿大人在总体严重程度（分别为0.57和0.50）、气息声（分别为0.45和0.45）和无力感（分别为0.50和0.46）方面有中等程度的一致性；在粗糙度方面相关性较差（分别为0.19和0.007）；在连贯言语的紧张度方面相关性较弱（0.22），在持续元音的紧张度方面相关性中等（0.50）。
总体而言，在GRBAS量表感知参数的大多数维度上，听觉感知评估不受母语影响。
