Abstract

Abstract:

Objective To investigate the acoustic characteristics and phonological features of glottal stops in Mandarin-speaking individuals with cleft palate. Methods Consonant and vowel (CV) syllable speech samples with glottal stops replacing the initial consonants /g/, /j/, and /s/ were extracted from the cleft palate speech database as the patient group, while two CV syllable speech samples from healthy volunteers served as the control group. Using the Praat^@6.1.09, parameters including syllable duration, the first two formants(F1, F2), the vowel space, and spectral moments(M1-M4) of the consonant were extracted. Time-domain and frequency-domain correlation analyses were conducted, and phonological differences among the target consonants(/g/, /j/, /s/)were examined. Results Statistically significant differences(P<0.05)were ide.PNGied between the cleft group and the control group in terms of syllable duration, the F1 value of the vowel /a/, the F2 value of the vowel /i/, and the spectral moments(M1-M4) of the initial consonants. Within the cleft group, a negative correlation was observed between syllable duration and M1(r=-0.595, P<0.001). Furthermore, in the cleft group, M1 and F1 demonstrated a significant positive correlation(r=0.243, P<0.05). When comparing glottal stops across different target consonants, significant inter-phonemic differences were found in consonant duration and the values of M3/M4(duration: P<0.001; M3/M4: P<0.05). Conclusion This research offers a comprehensive analysis of the acoustic features associated with glottal stop substitution in Mandarin-speaking adults with cleft palate. The study introduces an innovative approach to qua.PNGying phonological distinctions in substitution patterns across different target consonants. It suggests that patients may be able to achieve phonemic differentiation by adjusting the duration and spectral characteristics of glottal stops. These insights contribute to a deeper understanding of the phonological mechanisms underlying cleft palate speech and the production of glottal stops.
