Abstract

This study explores the role of rap music in lexical tone normalization among Mandarin speakers, addressing a gap in existing research that primarily focuses on speech contexts. While previous studies suggest that tone normalization is largely speech-specific, rap music, which combines elements of both speech and music, may provide unique insights. We examined the effects of rap, cello, and drum contexts compared to typical speech contexts. Our findings reveal that rap music, unlike purely instrumental music, elicited tone normalization effects similar to those of speech. This suggests that the pitch information in rap music may activate cognitive mechanisms akin to those used in speech processing.

The presence of human voices in rap creates a frame of reference, enabling listeners to normalize tones based on contextual pitch information. This challenges the notion that lexical tone normalization is exclusive to speech, highlighting the potential for speech-like elements in music to influence auditory perception. Our research underscores the importance of vocal elements in tone normalization and suggests that rhythm alone is not a critical factor.

Future research should investigate other speech-like materials and include participants with diverse linguistic and musical backgrounds to deepen our understanding of these mechanisms. By expanding the scope of contexts and participant diversity, we aim to further elucidate the cognitive processes underlying tone normalization and its broader implications for language education, rehabilitation, and AI technologies.
