equivalent Singapore Mandarin disyllabic
word list for clinical speech audiometry use
بخشی از متن:Abstract Objective: The aim of this study is to develop and evaluate a set of psychometrically
equivalent disyllabic wordlist (SC-10) in Singapore Mandarin for clinical use.
Study design: A preliminary set of 1000 words were obtained from a dictionary of frequently
used words by Singapore students. Ten native judges rate the familiarity level of each word.
This is followed by a face-to-face public survey to rank the shortlisted word set from most
to least familiar. The final 108 disyllabic words were recorded by a native female talker. 20
normal hearing subjects were used to obtain the percentage of correct word recognition at
24 intensity levels (10 dB HL to 26 dB HL in 2 dB increment). Psychometric function slopes
were calculated for each word. 100 words were eventually chosen and assigned into ten 10-
word lists based on a psychometric balancing protocol. Minor digital adjustments were made
to the intensity of each wordlist to improve their auditory homogeneity.
The developed SC-10 wordlists were validated by a separate group of 25 normal hearing subjects.
Test-retest reliability was carried out on 20 out of 25 participants at the selected intensity
levels (SRT-5, SRT, SRTþ5
