This study examined relationships among the Korean aging voice index (KAVI), the self-awareness index of voice problems (SAIVP), and the Korean voice handicap index (KVHI), and tested whether KAVI and SAIVP predict KVHI. A total of 183 adults aged 30–88 years participated. Descriptive statistics showed substantial individual variability in subjective voice perception and discomfort. Correlations were significant for KAVI–KVHI (r=.675, pr=.832, pr=.577, pp<.001), with SAIVP showing a stronger contribution. These findings indicate that the three measures are significantly associated with subjective voice perception and perceived discomfort across adult aging. SAIVP may serve as a brief screening tool; KAVI may support early detection of age-related voice changes, and KVHI may quantify voice handicap. The present study underscores the importance of early assessment and intervention for voice-related concerns in adults, including older adults.
