Abstract	The ability to identify stop consonants from brief onset spectra was compared between a group of Chinese children with phonological dyslexia (the PD group, with a mean age of 10 years 4 months) and a group of chronological age-matched control children. The linguistic context, which included vowels and speakers, and durations of stop onset spectra were varied. Children with PD showed lower identification accuracy and exhibited a smaller vowel context effect for some stop-vowel combinations compared with the chronological age-matched control group. Further analyses revealed that the PD group had more variable response patterns, and their responses were less consistent with the acoustic characteristics of stop onset spectra. The results suggest that Chinese children with PD do not show greater sensitivity to allophonic acoustic variability compared with control children and exhibit a generally less robust response pattern to phonetic categories.
