Abstract: A brand new research reveals a near-universal affiliation between the trilled R sound and tough textures or jagged shapes, whereas the L sound aligns with clean textures or straight traces. Researchers examined over 1,000 members talking 28 languages and located that 94% matched the trilled R to jagged traces and 84% matched L to clean traces, even amongst audio system of languages with out a trilled R.
This phenomenon surpasses the well-known bouba/kiki impact in consistency throughout cultures, shedding mild on sound symbolism in language. The findings recommend these associations could have influenced the evolution of spoken languages, making trilled R sounds prevalent regardless of their issue to articulate.
Key Information:
- 94% of members matched the trilled R with jagged traces, exhibiting a strong cross-cultural sample.
- The impact was constant even in languages with out the trilled R, corresponding to Mandarin and Japanese.
- The R/L affiliation with texture and form surpasses the bouba/kiki impact in universality.

Individuals all over the world affiliate a trilled R sound with a tough texture and a jagged form, and an L sound with clean texture and a flat form, in line with the findings of a brand new research.
Researchers consider this affiliation could also be extra common than the well-known bouba/kiki impact.
New analysis from the College of Birmingham (UK), printed at present (20th Nov) within the Journal of the Acoustical Society of America, has discovered one of many strongest instances ever documented of “sound symbolism” – a direct hyperlink between speech sounds and that means.
Marcus Perlman, Affiliate Professor in Linguistics and Communication on the College of Birmingham mentioned: “Our analysis exhibits that speech sounds have texture and form to them.
“In a earlier research, we discovered that throughout languages, R sounds are extra widespread in adjectives describing tough versus clean surfaces. This could possibly be resulting from a type of iconicity – a resemblance between the sound of the phrase and the feel to which it refers.
“On this research, we wished to see if there was a perceptual connection between the trilled R sound and roughness.
“Probably the most well-known instance of sound symbolism in spoken language is the bouba/kiki impact, the place nonsense phrases like ‘bouba’ are matched to spherical shapes, versus phrases like ‘kiki’, that are matched to angular shapes.
“In a comparable experiment, we beforehand demonstrated the bouba/kiki impact with audio system of various languages, however the R/L impact seems a lot stronger and extra constant throughout cultures.
“These sorts of cross-modal correspondences may need influenced the evolution of spoken languages, shaping the phrases we use to speak about texture and form.”
From Albanian to Zulu
The researchers performed their research by way of on-line and area experiments involving 1030 adults who spoke a complete of 28 completely different languages, together with Zulu, Albanian, Danish, English, Greek, Italian, Farsi, Spanish, Russian, Japanese, Korean, Mandarin Chinese language, Thai, Daakie and Palikúr. Members had been introduced with pictures of two traces – one jagged and one straight – and had been requested to think about working their fingers alongside every.
They had been then performed a recording of a speaker producing a trilled R (a rolled “R” sound, like in Spanish) and an L-sound and matched every sound to one of many traces.
The analysis confirmed that the good majority of members displayed a robust tendency to match R with the jagged line and L with the straight line, no matter which was introduced first.
The sample was strongest for matching the trilled R to the jagged line (94% on unbiased trials), nevertheless it was additionally very robust for matching L to the straight line (84% on unbiased trials).
Audio system of languages together with Estonian and Finnish had the very best match fee of 100%, with the bottom at 70% for audio system of languages together with Albanian and Mandarin Chinese language.
The trilled R connection to roughness appeared throughout audio system of all languages no matter whether or not the sound was utilized in that language or not. For instance, audio system of Palikúr, a language that’s utterly missing in a trilled R, carried out matching at 100%.
Along with the proof from languages which don’t commonly use the trill, corresponding to Mandarin Chinese language and Japanese, this exhibits that even when audio system can’t produce sound, they nonetheless understand it to be tough and jagged.
Close to-universal hyperlink between speech and texture
The outcomes are the strongest case ever documented of an iconic correspondence between speech sounds and properties associated to our senses of contact and imaginative and prescient.
Bodo Winter, Professor of Linguistics on the College of Birmingham commented: “General the findings from our experiments are much more constant than within the cross-cultural investigation of the bouba/kiki impact.
“Almost all members in our research thought R is rougher than L, about 15% greater than for the bouba/kiki impact. This sample was exceptionless throughout cultures: each single language group confirmed the identical affiliation.
“That is completely different from bouba/kiki, which doesn’t work in some languages. Evidently the connection between R/L and roughness/smoothness could also be probably the most cross-culturally sturdy instances of sound symbolism documented up to now.”
The researchers additionally discovered that, whereas there was an general excessive common match fee throughout languages, members whose native language primarily makes use of the alveolar trill R had a barely decrease proportion of right matches (86.6%) in comparison with these whose native language doesn’t use this sound as the first variant (89.8%).
This means that the traditional use of the sound diminishes its iconic energy.
Dr Perlman concluded: “The trilled R is among the many most fascinating of speech sounds. It’s notoriously tough for audio system to supply, and a few languages also have a phrase for individuals who can’t ever be taught to supply this sound (“Erre moscia” in Italian). And but trilled Rs are surprisingly widespread throughout languages.
“It’s a thriller why such a tough sound can be so prevalent. We predict the iconicity of R has one thing to do with it.
“The sound can convey such a robust sense of texture and form, and it has this extraordinary expressive worth that drives individuals to make use of the sound even when it’s comparatively exhausting to articulate. Additionally, it’s a really thrilling sound and a whole lot of enjoyable to produce!”

“The alveolar trill is perceived as jagged/tough by audio system of various languages” by Marcus Perlman et al. Journal of the Acoustical Society of America
Summary
The alveolar trill is perceived as jagged/tough by audio system of various languages
Typological analysis exhibits that throughout languages, trilled [r] sounds are extra widespread in adjectives describing tough versus clean surfaces.
On this research, this lexical analysis is constructed on with an experiment with audio system of 28 completely different languages from 12 completely different households.
Members had been introduced with pictures of a jagged and a straight line and imagined working their finger alongside every. They had been then performed an alveolar trill [r] and an alveolar approximant [l] and matched every sound to one of many traces.
Members confirmed a robust tendency to match [r] with the jagged line and [l] with the straight line, much more constantly than in a comparable cross-cultural investigation of the bouba/kiki impact.
The sample is strongest for matching [r] to the jagged line, but additionally very robust for matching [l] to the straight line.
Whereas this impact was discovered with audio system of languages with completely different phonetic realizations of the rhotic sound, it was weaker when trilled [r] was the first variant. This means that when a sound is used phonologically to make systemic that means contrasts, its iconic potential could change into extra restricted.
These findings lengthen our understanding of iconic crossmodal correspondences, highlighting deep-rooted connections between auditory notion and contact/imaginative and prescient.
