Acoustics versus articulation: What is sound symbolism based on?
Wed-A6-Talk VII-03
Presented by: Bodo Winter
Sound symbolism refers to the association of phonemes with non-speech phenomena, such as when /i/ is small (Sapir, 1929), or when “bouba” sounds rounder than “kiki” (Ćwiek et al., 2022). These associations have been shown to matter in language acquisition and processing (Kita & Imai, 2014; Lockwood & Dingemanse, 2015). A so-far inconclusive debate surrounds the psychological mechanism that underpins sound symbolism, specifically whether articulation or acoustics lie at the root of such mappings (e.g., Eberhardt, 1940; Johansson & Zlatev, 2013; Newman, 1933; Sapir, 1929). Recent proposals emphasize articulatory mechanisms (Thompson & Do, 2019; Vainio et al., 2019). In this talk, I will argue that the search for a monolithic locus of sound symbolism is futile, not only because acoustics and articulation are tightly coupled and hard to orthogonalize experimentally, but also because we already know from the existing experimental literature that different sound symbolic phenomena are supported by different mechanisms. Moreover, the same sound symbolic can actually be supported by multiple different mechanisms. I conclude with a call to move beyond the articulation versus acoustics debate in discussing sound symbolic mechanisms. Instead, emphasis should shift to considering networks of phonetic cues, both articulatory and acoustic in nature.
