Description
Summary:This study was designed to develop language-specific stimuli for the assessment of resonance and to obtain nasalance scores using the newly developed speech stimuli in Mandarin. Gender and age influences on nasalance scores for each of the stimulus were also examined. Participants recruited were typically developing Mandarin-speaking ethnic Chinese children aged 6;00-7;11 growing up in Malaysia. Perceptual ratings of nasality were made based on the GOS.SP.ASS.'98 (revised) for children while nasalance scores were recorded for each stimulus using the Nasometer II (Model 6400). Fifty Mandarin-speaking children (24 males and 26 females) were recruited. None of the participants were perceived with abnormal nasality on the three stimuli. The mean nasalance scores for the Mandarin stimuli were 16.08% (SD = 2.57, 95% CI = 15.35-16.81) for the Oral passage, 25.20% (SD = 3.63, 95% CI = 24.17-26.23) for the Oral-Nasal passage and 55.44% (SD = 4.17, 95% CI = 54.25-56.63) for the Nasal passage. No significant age- and gender-related differences were observed for all the three stimuli. This is the first set of Mandarin stimuli and nasalance norms for Mandarin-speaking children in Malaysia. The influence of phonetic content on nasalance is supported. Findings call for language-specific normative nasalance data and careful selection of stimuli for the assessment of resonance.
