Exploring the perception–production link in bilingual voices
Sylvia Cho · The Journal of the Acoustical Society of America · 2025
In language acquisition research, some studies have found a strong relationship between perception and production, while others have not found a perception–production link. While the relationship between perception and production has been explored for segmental and non-segmental contrasts, less attention has been given to exploring this relationship between voice perception and production. The goal of the present study is, therefore, to evaluate the link between the acoustic variability found in voice production and the processes of speaker identification in voice perception. To explore this, 24 filter and source-based acoustic measurements are estimated for Korean-English bilingual voices, and these features will be compared to perceptual discrimination ratings of these voices [J. Acoust. Soc. Am. 155, A274 (2024)]. The results will be reported in relation to the relationship between acoustic variability found within and across speakers and its effects on voice quality and speaker identity.
