Significant differences exist in anatomical, acoustic, and aerodynamic parameters for nonspeech tasks between culturally and linguistically diverse sample populations. There is a need for expansion of the normative acoustic data to include sociolinguistically diverse groups to ensure that clinical objective measurements are accurately classifying the voice quality of all individuals. This study examined objective measures of voice quality assessment of monolingual speakers of Standard American English (SAE) with sequential bilingual, native (L1) French and Spanish speakers on perturbation, noise, spectral/cepstral analyses, and compared ratings on auditory-perceptual assessment with acoustic data secondary to degree of accentedness.
Thirty speakers with normal voice quality were rated on the Consensus Auditory-Perceptual Evaluation of Voice scale. Voice quality measures were analyzed using the Multi-Dimensional Voice Program and Analysis of Dysphonia in Speech and Voice. A measure of accentedness of SAE was calculated using an informal task by two evaluators.
Objective acoustic measures of jitter and all-voiced cepstral peak prominence were statistically significant between SAE speakers and L1 Spanish and French speakers. SAE speakers demonstrated significantly higher group mean cepstral peak prominence for the all-voiced sentence ("We were away a year ago.") than native French and Spanish speakers. There were no significant differences in perception of voice quality and acoustic measures secondary to degree of accentedness of the non-native SAE speakers.
It is important to engage and strengthen voice diagnostic measures to support culturally competent service delivery for the diversifying clinical population. Normative databases established on SAE speakers should reflect the statistically significant differences evidenced between diverse sociolinguistic populations in anatomical, auditory-perceptual, aerodynamic, and acoustical parameters.
在文化和语言多样化的样本人群中，非言语任务的解剖学、声学和空气动力学参数存在显著差异。需要扩展规范的声学数据，包括社会语言多样化群体，以确保临床客观测量准确地对所有个体的语音质量进行分类。本研究检查了单语母语为标准美式英语（SAE）的个体与顺序双语母语为法语和西班牙语的个体的嗓音质量评估的客观测量指标，对感知评估的听觉进行了比较，并对嗓音障碍的声学分析和分析进行了比较，这与口音的严重程度有关。
30 名具有正常嗓音质量的发音者在共识听觉感知嗓音评估量表上进行了评分。使用多维嗓音程序和语音嗓音障碍分析对嗓音质量指标进行了分析。通过两位评估者的一项非正式任务，计算了 SAE 口音的严重程度。
在 SAE 发音者和母语为西班牙语和法语的发音者之间，抖动和全音嗓音倒谱峰值突出度的客观声学测量值存在统计学差异。SAE 发音者在所有发音的句子（“We were away a year ago.”）中的组平均倒谱峰值突出度显著高于母语为法语和西班牙语的发音者。在感知嗓音质量和非母语 SAE 发音者的口音严重程度的声学测量值方面，没有显著差异。
对于不断多样化的临床人群，为了提供文化上合格的服务，参与和加强嗓音诊断措施非常重要。在 SAE 发音者建立的规范数据库应反映出在解剖学、听觉感知、空气动力学和声学参数方面，不同社会语言群体之间存在的统计学显著差异。
