从语言锚点到声学骨架：语音身份表征的双途径模型

Achieving perceptual constancy for voice identity across the speech-song continuum represents a fundamental cognitive challenge. Does the auditory system rely on precise linguistic cues to "anchor" identity, or does it utilize multi-dimensional acoustic variability to build a generalized prototype? In this study, we trained listeners to recognize voices via three modalities, i.e., reading (linguistic focus), non-lexical singing on /la/ (structural focus), and singing (dual focus). We then tested their recognition of the voices under immediate, cross-modal, and one-week delayed conditions. Expe
