Abstract

Background and objectives: Monosyllable words are the most common speech recognition stimuli since they test auditory perception and are used to assess speech recognition. However, there is a lack of resources available for the Urdu-speaking Pakistani population. This study aims to develop and psychometrically evaluate a digitally recorded Urdu monosyllabic word list for Word Recognition Score (WRS) testing.

Subjects and methods: A total of 135 monosyllabic words were selected from a previous study. These words were digitally recorded by a native female Urdu speaker in a studio. The recordings were psychometrically assessed by 30 native Urdu speakers with normal hearing. The 100 most familiar words were selected and organized into two lists, each further divided into four halves to ensure that the words were relatively homogeneous in terms of audibility.

Results: The average psychometric slope between 20% and 80% for the full list was 4.78%/dB±0.22%/dB, while it was 4.81%/dB±0.35%/dB for the half list. No statistically significant difference in p-values was observed between the full and half lists. The mean psychometric slope for 50% intelligibility was 6.04%/dB for both the full list (SD=0.44) and the half lists (SD=0.40).

Conclusions: Digitally recorded Urdu monosyllabic word lists are valid for assessing speech recognition in native Urdu speakers with normal hearing.

数字记录乌尔都语单音节词表用于词识别得分测试的心理测量学评价。

背景和目的：单音节单词是最常见的语音识别刺激，因为它们测试听觉感知并用于评估语音识别。然而，对于说乌尔都语的巴基斯坦人来说，缺乏可用的资源。本研究的目的是开发一个数字记录的乌尔都语单音节词表，并对其进行心理测量学评价。对象与方法：选取已有的单音节单词135个。这些话是由一名讲乌尔都语的当地女性在演播室里用数字技术录下来的。录音由30名听力正常的乌尔都语母语者进行心理测量学评估。100个最熟悉的单词被挑选出来并组织成两个列表，每个列表进一步分成四部分，以确保单词在可听性方面相对均匀。结果：全表心理测量斜率为4.78%/dB±0.22%/dB，半表心理测量斜率为4.81%/dB±0.35%/dB。p值在全表和半表之间没有统计学上的显著差异。50%可理解度的平均心理斜率在完整列表（SD=0.44）和半列表（SD=0.40）中均为6.04%/dB。结论：数字记录的乌尔都语单音节词表可用于评估听力正常的乌尔都语母语者的语音识别。

期刊介绍： Journal of Audiology and Otology (JAO) (formerly known as Korean Journal of Audiology) aims to publish the most advanced findings for all aspects of the auditory and vestibular system and diseases of the ear using state-of-the-art techniques and analyses. The journal covers recent trends related to the topics of audiology, otology, and neurotology conducted by professionals, with the goal of providing better possible treatment to people of all ages, from infants to the elderly, who suffer from auditory and/or vestibular disorders and thus, improving their quality of life. This journal encourages the submission of review papers about current professional issues, research papers presenting a scientific base and clinical application, and case papers with unique reports or clinical trials. We also invite letters to the editor and papers related to the manufacture and distribution of medical devices. This journal provides integrated views from otologists, audiologists, and other healthcare practitioners, offering readers high quality scientific and clinical information. This peer-reviewed and open access journal has been the official journal of the Korean Audiological Society since 1997 and of both the Korean Audiological Society and the Korean Otological Society since 2017. It is published in English four times a year in January, April, July, and October.
