Abstract

Word recognition tests must be conducted in the native language of the listener to obtain valid word recognition scores. Existing Singapore Mandarin speech audiometry test materials that are disyllabic lack in sensitivity and are not phonologically balanced. The purpose of this study was to address those limitations and develop a set of word lists for testing speakers of Singapore Mandarin. The word lists were developed over three phases. (1) Frequently occurring words were chosen from a database consisting of subtitles from local Mandarin programmes, and subjected to familiarity rating by 50 native Singapore Mandarin speakers. (2) Phonologically balanced word lists were created and professionally recorded using words rated as familiar in phase 1. (3) Psychometric curves of words were obtained from 20 normal-hearing native speakers and word lists were analysed for perceptual equivalence. Sixteen phonologically balanced word lists consisting of 25 monosyllables each were created in phase 2. Eight of the 16 lists were found to be perceptually equivalent. Word lists developed in this study addressed the limitations of existing Singapore Mandarin speech audiometry materials. The word lists need to be validated with normal-hearing and hearing-impaired Singapore Mandarin speakers before they can be used clinically.

用于单词识别测试的语音平衡和感知等效的新加坡普通话单词表的开发
单词识别测试必须以听者的母语进行,以获得有效的单词识别分数。现有的新加坡普通话语音测听测试材料是双音节的,缺乏灵敏度,语音不平衡。本研究的目的是为了解决这些限制,并开发一套单词表来测试新加坡普通话的使用者。单词表的发展经历了三个阶段。(1)从本地普通话节目的字幕数据库中选择常用词,并由50名新加坡普通话母语者进行熟悉度评分。(2)使用在第一阶段被评为熟悉的单词,创建语音平衡的单词表并进行专业记录。(3)对20名听力正常的母语人士进行词汇心理测量曲线分析,并对词汇表进行感知等值分析。在第二阶段创建了16个语音平衡的词表,每个词表由25个单音节组成。16个列表中有8个被发现在感知上是相同的。本研究开发的词表解决了现有新加坡普通话语音测听材料的局限性。这些单词表在临床使用之前,需要在听力正常和听力受损的新加坡普通话使用者中进行验证。
