Sounds cute: Exploring the role of sound reduplication in brand names

Reduplication, a linguistic feature in which part or all of a word is repeated (e.g., “kuku,” in which the syllable “ku” is doubled), is widely observed across languages and plays a significant role in child-directed speech, language acquisition, and even adult communication (e.g., “knock knock”). Despite its prevalence, reduplication remains one of the least studied aspects of brand names, and little is known about its impact on consumer perception. This study investigates how reduplicated sounds in brand names affect consumer preferences, revealing that such names enhance brand appeal by triggering associations with baby-schema cuteness. Additionally, this research identifies two key moderators: brand–product fit and the perceived cuteness of specific phonemes, such as bilabial sounds (e.g., “m” and “p”). These findings advance our understanding of brand naming and cute branding, offering practical insights for companies looking to increase brand attractiveness through sound-based cuteness.
