Abstract
The study aimed at developing a Thai version of monosyllable word lists and picture lists to provide clinical hearing evaluations for pre-school children and to validate the reliability of the Thai version of the monosyllable word lists for two different age groups (2-3 years vs. 4-5 years). The monosyllable word lists and picture lists were developed in accordance with the following steps: 1) the familiarity of 100 words was chosen; 2) the pictures that represented the meanings of the matched 80 words were developed; 3) both the receptive and expressive vocabulary were evaluated in 62 children 2-3 years of age (Group 1) and in 62 children 4-5 years of age (Group 2); 4) monosyllable words were analyzed using a computerized speech lab and were arranged into sets of word lists (Khon Kaen University (KKU) kid word lists-A for Group 1 and KKU kid word lists-B for Group 2) with phonetically balanced fundamental frequency, the Thai five tones, and the initial consonants; 5) the word lists were recorded; and 6) The KKU kid word lists-A & B were validated with 31 children from each group, respectively. KKU kid word lists-A had word recognition scores (WRS) with a mean of above 90% for each list in passing and referring to the hearing screening ears. KKU kid word lists-B had a WRS of over 92% for each list. The development of the Thai monosyllable word lists was determined to be appropriate for assessing the WRS of pre-school children for conducting clinical hearing evaluations.
