The selection of material is important in the development of a paediatric speech perception test. Even though several studies have documented various sources of speech testing materials, using corpus was recommended to develop a Matrix Sentence Test (MST). However, as available Malay corpus was limited to written words only, this research aims to construct a Paediatric Malay corpus from a combination of written and spoken words of children in Malaysia and to develop word-based matrix (WBM) for the Paediatric Malay Matrix Sentence Test (PaedMalayMST) based on the developed corpus. The WBM replicates the Malay grammatical structure in these three categories: number, object, and adjective. Based on these criteria, the words from the developed corpus were then filtered by considering the frequency of occurrences and its phonemic distributions to be included in the WBM. As a result, a matrix of three categories with six words for each category was constructed. [ABSTRACT FROM AUTHOR]

Background: Auditory brainstem response (ABR) to the level-specific (LS) CE-Chirp has been reported to provide optimum neural synchrony along cochlear partitions, theoretically improving ABR waveform resolution. Despite this promising finding, limited studies have been conducted to contrast the results between LS CE-Chirp and Click stimuli. The current study aimed to compare the results of ABR between the two stimuli (Click and LS CE-Chirp). Method: Sixty-seven normal-hearing infants, both with and without risk factors, aged less than 7 months old, participated in this study. The ABR test was conducted at 70 dBnHL using 33.3 stimulus repetition rates with both Click and LS CE-Chirp stimuli. The signal averaging was stopped at a maximum fixed signal average of 2,500 sweeps. Data were statistically compared between the two stimuli using the Wilcoxon signed-rank test. Results: The waves I and V ABRs elicited by LS CE-Chirp exhibited significantly larger amplitudes than the Click stimulus. However, the amplitude of wave III and absolute latencies were similar in both stimuli at a supra-threshold level. Conclusion: LS CE-Chirp has the advantage of larger amplitudes than the ABR from Click at the supra-threshold level (70 dBnHL) in normal-hearing infants. [ABSTRACT FROM AUTHOR]
