Abstract:
Objective To study the characteristics and correlation of tone perception and production in Man-darin Chinese in children with autism spectrum disorder(ASD).Methods Thirty-one children with ASD and 26 normal children were tested on their recognition of the four Mandarin tones.Simultaneously,the acoustic features of the four tones produced in the words"wa1"(frog,with first tone),"wa2"(doll,with second tone),"wa3"(tile,with third tone),and"wa4"(sock,with fourth tone)were analyzed and compared between the two groups.Results The ASD group exhibited significantly lower recognition accuracy rates for all four tones compared to the control group(P＜0.05),with highly significant differences for the second and third tones(P＜0.001).Significant differ-ences were also found in the standard deviation of the fundamental frequency(F0)for the production of all four tones between the ASD and control groups.Furthermore,the slope of the second tone and the turning point F0 and falling slope of the third tone showed significant differences(P＜0.05 or P＜0.001).Correlation analysis revealed that the recognition accuracy of the second tone was positively correlated with the slope of the first and second tones and the F0 standard deviation.The recognition accuracy of the third tone was negatively correlated with the turning point F0,and that of the fourth tone was negatively correlated with the falling slope of the third tone.Conclusion Children with ASD demonstrate deficits in tone perception and production,with prominent difficulties in recognizing and producing the second and third tones,and overall instability in tone production.
