AI Insight
This study investigated whether the sound of words relates to their perceived roundness or pointedness by having participants rate both real words and invented pseudowords. Researchers analyzed 12 acoustic parameters and found similar correlations between sound properties and shape ratings for both real and invented words. The findings suggest that iconicity—the non-arbitrary relationship between how words sound and what they mean—operates similarly in actual language as it does in made-up words like "bouba" (round-sounding) and "kiki" (sharp-sounding).
Why it matters
This research provides evidence that real words in natural language contain systematic sound-meaning mappings, not just invented examples used in experiments. Understanding these acoustic-semantic relationships could inform language learning tools, brand naming strategies, and shed light on how languages evolve and how the human brain processes linguistic meaning.

Iconicity in spoken language refers to the mapping of speech sounds to meaning. For example, the pseudoword "bouba" is judged to sound rounded, whereas the pseudoword "kiki" is judged to sound pointed (Ramachandran & Hubbard, 2001). Recent work has found systematic relationships between speech acoustics and iconicity ratings in various meaning domains, including shape. To control for confounding by semantic knowledge, much research on iconicity relies on pseudowords. However, the role of iconicity in conveying the meanings of real words is still poorly understood. Here, we compared the relationship between speech acoustics and shape iconicity ratings for both pseudowords and real words. In this experiment, participants rated real words and pseudowords for how rounded or pointed they sounded. We compared the relationship between 12 acoustic parameters and the rounded/pointed ratings for both words and pseudowords. We found that the correlations between these acoustic parameters and the ratings were similar for real words and pseudowords, providing key evidence that iconicity of real words is linked to speech acoustics.
