Abstract

Objectives: The goal of this study was to determine if performance on speech and non-speech clinical measures of auditory perception differs between two groups of adults: self-identified native speakers of English and non-native speakers of English who speak Spanish as a first language. The overall objective was to establish whether auditory perception tests developed for native English speakers are appropriate for bilingual Spanish-speaking adults who self-identify as non-native speakers of English. A secondary objective was to determine whether relative performance on English- and Spanish-language versions of a closed-set speech perception in noise task could accurately predict native-like performance on a battery of English language-dependent tests of auditory perception.

Design: Participants were young, normal-hearing adults who self-identified as either native speakers of American English (n = 50) or as non-native speakers of American English (NNE; n = 25) who spoke Spanish as their first language. Participants completed a battery of perceptual tests, including speech tests (e.g., Quick Speech-in-Noise, time-compressed reverberant Quick Speech-in-Noise, etc.) and non-speech tests (Gaps in Noise, Frequency Pattern test, Duration Pattern test, Masking Level Difference). The English version of the Oldenburg Sentence test (OLSA) was administered to both groups; NNE participants also completed the Spanish version of the OLSA.

Results: Analyses indicate that the native speakers of the American English group performed significantly better than the NNE group on all speech-based tests and on the two pattern recognition tests. There was no difference between groups on the remaining non-speech tests. For the NNE group, a difference of more than 2 SD on group-normalized scores for the English and Spanish OLSA accurately predicted poorer than normal performance on two or more tests of auditory perception with a language-dependent component either in the instructions or the stimuli.

Conclusions: The results indicate that a number of English-based tests designed to assess auditory perception may be inappropriate for some Spanish-English bilingual adults. That is, some bilingual adults may perform worse than expected on tests that involve perceiving spoken English, in part because of linguistic differences, and not because of unusually poor auditory perception. The results also support the use of preliminary speech-in-noise screening tests in each of a bilingual patient's languages to establish if auditory perception tests in English are appropriate for a given individual. If a non-native English speaker's screening performance is worse in English than in the native language, one suggested strategy is to select auditory perceptual tests that are impacted minimally or not at all by linguistic differences.

非英语母语者的语音和非语音听觉任务表现。
研究目的本研究的目的是确定两类成年人在听觉感知的语音和非语音临床测量上的表现是否存在差异,这两类成年人分别是自我认定的英语为母语者和以西班牙语为母语的非英语为母语者。总体目标是确定为英语为母语者开发的听觉感知测试是否适用于自我认定为非英语为母语的西班牙语双语成人。另一个次要目标是确定英语和西班牙语版本的噪音中封闭式语音感知任务的相对成绩是否能准确预测英语母语听觉感知测试的成绩:参与者均为听力正常的年轻成年人,他们自我认同为母语为美式英语(n = 50)或母语为西班牙语的非美式英语使用者(NNE;n = 25)。受试者完成了一系列感知测试,包括语音测试(如快速噪音语音测试、时间压缩混响快速噪音语音测试等)和非语音测试(噪音间隙、频率模式测试、持续时间模式测试、掩蔽水平差异)。两组受试者均进行了英语版的奥尔登堡句子测试(Oldenburg Sentence test,OLSA);NNE 受试者还完成了西班牙语版的 OLSA:分析表明,在所有语音测试和两项模式识别测试中,美式英语组母语人士的表现明显优于非英语人士组。在其余非语音测试中,各组之间没有差异。对于 NNE 组,如果英语和西班牙语 OLSA 的组内标准化分数相差超过 2 SD,则可准确预测其在两项或更多听觉感知测试中的表现差于正常水平,这些测试的指令或刺激都有语言依赖成分:研究结果表明,一些以英语为基础的听觉感知测试可能不适合某些西英双语成年人。也就是说,一些双语成人在涉及英语口语感知的测试中的表现可能比预期的要差,部分原因是语言差异,而不是因为听觉感知能力异常差。研究结果还支持用双语患者的每种语言进行初步的噪音语音筛选测试,以确定用英语进行的听觉感知测试是否适合特定个体。如果非英语母语者的英语筛查表现比母语者差,建议的策略之一是选择受语言差异影响最小或完全不受语言差异影响的听觉感知测试。

期刊介绍: From the basic science of hearing and balance disorders to auditory electrophysiology to amplification and the psychological factors of hearing loss, Ear and Hearing covers all aspects of auditory and vestibular disorders. This multidisciplinary journal consolidates the various factors that contribute to identification, remediation, and audiologic and vestibular rehabilitation. It is the one journal that serves the diverse interest of all members of this professional community -- otologists, audiologists, educators, and to those involved in the design, manufacture, and distribution of amplification systems. The original articles published in the journal focus on assessment, diagnosis, and management of auditory and vestibular disorders.
