This paper analyzes the vocative truncation pattern in Korean from the viewpoint of Message-Oriented Phonology (MOP), which capitalizes on the idea that sound patterns are governed by a principle that makes message transfer effective. In the traditional naming pattern, Korean first names consist of a generation marker and a unique portion, and the order between these two elements alternates between generations. To derive vocative forms, the generation marker is truncated, and the suffixal [(j)a] is attached to the unique portion. We argue that MOP naturally predicts this type of truncation. As the generation marker is shared by all the members of the same generation, the generation marker is highly predictable and hence does not reduce uncertainty about the intended message. To achieve effective communication, predictable portions are deleted. Our analysis implies that MOP is relevant not only to phonetic implementation patterns, but also to morphophonological patterns. It also provides support for MOP based on data from a non-Indo-European language. Finally, we aim to integrate insights of MOP with a more formal proposal like Optimality Theory, by relating the predictability of a contrast to the ranking of the faithfulness constraint that it protects, following the spirit of the P-map hypothesis.

Linguistic communication requires speakers to mutually agree on the meanings of words, but how does such a system first get off the ground? One solution is to rely on iconic gestures: visual signs whose form directly resembles or otherwise cues their meaning without any previously established correspondence. However, it is debated whether vocalizations could have played a similar role. We report the first extensive cross-cultural study investigating whether people from diverse linguistic backgrounds can understand novel vocalizations for a range of meanings. In two comprehension experiments, we tested whether vocalizations produced by English speakers could be understood by listeners from 28 languages from 12 language families. Listeners from each language were more accurate than chance at guessing the intended referent of the vocalizations for each of the meanings tested. Our findings challenge the often-cited idea that vocalizations have limited potential for iconic representation, demonstrating that in the absence of words people can use vocalizations to communicate a variety of meanings.

Sound symbolism, systematic associations between sounds and meanings, is receiving increasing attention in linguistics, psychology and related disciplines. One general question that is currently explored in this research is what sorts of semantic properties can be symbolically represented. Against this background, within the general research paradigm which explores the nature of sound symbolism using Pokémon names, several recent studies have shown that Japanese speakers associate certain classes of sounds with notions that are as complex as Pokémon types. Specifically, Japanese speakers associate (1) sibilants with the flying type, (2) voiced obstruents with the dark type, and (3) labial consonants with the fairy type. These sound symbolic effects arguably have their roots in the phonetic properties of the sounds at issue, and hence are not expected to be specific to Japanese. The current study thus addressed the question whether these sound symbolic associations hold with native speakers of English. Two experiments show that these sound symbolic patterns were very robustly observed when the stimuli were presented in pairs; when the stimuli were presented in isolation, the effects were also tangible, although not as robust. We conclude that English speakers can associate certain types of sounds with particular Pokémon types, with an important caveat that we observed a clear task effect. Overall the current results lend some credibility to the hypothesis that those attributes that play a role in Pokémons' survival are actively signaled by sound symbolism.

This paper argues that phonology and orthography go in tandem with each other to shape our phonological behavior. More concretely, phonological operations are non-trivially affected by orthography, and phonological constraints can refer to them. The specific case study comes from a morphophonological alternation in Japanese, rendaku. Rendaku is a process by which the first consonant of the second member of a compound becomes voiced (e.g., /oo/ + /tako/ → [oo+dako] 'big octopus'). Lyman's Law blocks rendaku when the second member already contains a voiced obstruent (/oo/ + /tokage/ → ∗[oo+dokage], [oo+tokage] 'big lizard'). Lyman's Law, as a constraint which prohibits a morpheme with two voiced obstruents, is also known to trigger devoicing of geminates in loanwords (e.g. /beddo/ → [betto] 'bed'). Rendaku and Lyman's Law have been extensively studied in the past phonological literature. Inspired by recent work that shows the interplay between orthographic factors and grammatical factors in shaping our phonological behaviors, this paper proposes that rendaku and Lyman's Law actually operate on Japanese orthography. Rendaku is a process that assigns dakuten diacritics, and Lyman's Law prohibits morphemes with two diacritics. The paper shows that a set of properties of rendaku and Lyman's Law follows from this proposal. However, since some aspects of rendaku and Lyman's Law are undoubtedly phonological, the ultimate conclusion is that it is most fruitful to recognize a model of phonology in which it has access to orthographic information. Several consequences of the current proposal are discussed.

This paper reports two case studies of sound symbolism using the naturalistic name corpora of characters from Disney and Pokémon. Building upon previous studies of sound symbolism, we tested two hypotheses: (1) voiced obstruents, which are generally associated with negative images, are favored in villainous characters' names, while (2) bilabial consonants, which are symbolically associated with cuteness, are disfavored in such names. The results show that these tendencies hold in our corpora, suggesting that a concept that is as complex as “villain” can be signaled via sound symbolism. Theoretical implications for cognitive linguistics based on our results are discussed.

Kawahara, Noto, and Kumagai (2018b) found that within the corpus of existing Pokémon names, the number of voiced obstruents in the characters' names correlates positively with their weight, height, evolution levels and attack values. While later experimental studies to some extent confirmed the productivity of these sound symbolic relationships (e.g. Kawahara and Kumagai 2019a), they are limited, due to the fact that the visual images presented to the participants primarily differed with regard to evolution levels. The current experiments thus for the first time directly explored how each of these semantic dimensions - weight, height, evolution levels, and attack values - correlates with the number of voiced obstruents in nonce names. The results of two judgment experiments show that all of these parameters indeed correlate positively with the number of voiced obstruents in the names. Overall, the results show that a particular class of sounds - in our case, a set of voiced obstruents - can signal different semantic meanings within a single language, supporting the pluripotentiality of sound symbolism (Winter, Pérez-Sobrino, and Brown 2019). We also address another general issue that has been under-explored in the literature on sound symbolism; namely, its cumulative nature. In both of the experiments, we observe that two voiced obstruents evoke stronger images than one voiced obstruent, instantiating what is known as the counting cumulativity effect (Jäger and Rosenbach 2006).

We used the corpus of all Japanese Pokémon names available as of October 2016. We tested the effects of voiced obstruents, mora counts, and vowel quality on Pokémon characters' size, weight, strength parameters, and evolution levels. We found that the number of voiced obstruents in Pokémon names correlates positively with size, weight, evolution levels, and general strength parameters, except for speed. We argue that this result is compatible with the frequency code hypothesis of Ohala. The number of moras in Pokémon names correlates positively with size, weight, evolution levels, and all strength parameters. Vowel height is also shown to have an influence on size and weight-Pokémon characters with initial high vowels tend to be smaller and lighter, although the effect size is not very large. Not only does this paper offer a new case study of sound symbolism, it provides evidence that sound symbolism is at work when naming proper nouns.

Four native Japanese speakers of varying levels of English acquisition and one North American English speaker were recorded both acoustically and with Electromagnetic Articulography. Seven distinct articulation strategies were identified. Results indicate that the least advanced speaker uses a single articulation strategy for both sounds. Intermediate speakers used a wide range of articulations, while the most advanced non-native speaker relied on a single strategy for each sound.

We introduce computational tools for assessing this possibility though simulation and classification of phonetic trajectories. The empirical material used to demonstrate the approach comes from electromagnetic articulography recordings of high-vowel devoicing in Japanese. Using Discrete Cosine Transform, tongue-dorsum movement trajectories are decomposed into a small number of frequency components (cosines differing in frequency and amplitude) that correspond to linguistically meaningful signal modulations, i.e. articulatory gestures. Stochastic generators of competing phonological hypotheses operate in this frequency space. Distributions over frequency components are used to simulate (i) the vowel-present trajectories and (ii) the vowel-absent trajectories. A Bayesian classifier trained on simulations assigns posterior probabilities to unseen data. Results indicate that /u/ is optionally produced without a vowel-height specification in Tokyo Japanese and that the frequency of such targetlessness varies systematically across phonological environments.

Many papers in this special issue grew out of the talks given at the Symposium "The role of predictability in shaping human language sound patterns," held at Western Sydney University (Dec. 10-11, 2016). Some papers were submitted in response to an open call; others were invited contributions. This introduction aims to contextualize the papers in the special issue within a broader theoretical context, focusing on what it means for phonological theory to incorporate gradient predictability, what questions arise as a consequence, and how the papers in this issue address these questions.

Previous corpus-based research identified some specific sound symbolic relationships in Pokémon naming patterns in Japanese (Kawahara et al. 2018b). One of the main findings was that the names of Pokémon characters are more likely to contain voiced obstruents, and are longer in terms of mora count, when the Pokémon characters undergo evolution (e.g. nyoromo → nyorozo; poppo → pijotto). The current study reports three experiments that test whether (i) these patterns are productive in the minds of general Japanese speakers, and whether (ii) the same tendency holds with English speakers. The results show that the effect of phonological length was clearly observed both with Japanese and English speakers; the effects of voiced obstruents were observed clearly with Japanese speakers, but less clearly with English speakers. Along the way, we address other general issues related to sound symbolism: (iii) to what extent the sound symbolic effects identified in Kawahara et al. (2018b) rely on familiarity with Pokémon, and (iv) whether word-initial segments invoke stronger images than word-internal segments. In addition to its research value, we emphasize that this general project on Pokémon names can be useful for undergraduate phonetics education.

Sound symbolism has not received much serious attention in the generative phonology literature, perhaps because most if not all sound symbolic patterns are probabilistic. Building on the recent proposal to analyze sound symbolic patterns within a formal phonological framework (Alderete and Kochetov 2017), this paper shows that MaxEnt grammars allow us to model stochastic sound symbolic patterns in a very natural way. The analyses presented in the paper show that sound symbolic relationships can be modeled in the same way that we model phonological patterns. We suggest that there is nothing fundamental that prohibits formal phonologists from analyzing sound symbolic patterns, and that studying sound symbolism using a formal framework may open up a new, interesting research domain. The current study also reports two hitherto unnoticed cases of sound symbolism, thereby expanding the empirical scope of sound symbolic patterns in natural languages.

Sound-symbolic patterns which relate to the perception of size were found to motivate the behavior of English and Japanese speakers in the naming of pre- and post-evolution Pokémon. The current study builds from this finding and investigates which sound-symbolic association speakers of Brazilian Portuguese (BP) employ to name Pokémon characters. Results from 3 experiments show that vowel quality, phonological length and voiced obstruents, usually used to signal differences in size, are used to signal differences in evolution; however, the effects of voiced obstruents are not identical to what was previously observed in the behavior of Japanese speakers. We argue that although there is a universal sound symbolism associated with these sounds and the perception of largeness, its manifestation differs cross-linguistically. To the best of our knowledge, this is one the first experimental research to investigate sound symbolism and the perception of size in BP.

This article contributes to the studies of sound symbolism, systematic relationships between sounds and meanings. Specifically, we build on a series of studies conducted within a research paradigm called "Pokémonastics,"which uses the Pokémon universe to explore sound symbolic patterns. Inspired by a study of existing English Pokémon names, two experiments were conducted in which English speakers were provided with pairs of pre-evolution and post-evolution Pokémon characters, the latter of which were larger. The participants were given two name choices whose members were systematically different in some phonological properties. The results show the following sound symbolic patterns to be productive: (1) names with higher segment counts are more likely to be associated with post-evolution characters than names with lower segment counts, (2) names containing [a] are more likely to be associated with post-evolution characters than names containing [i], (3) names containing [u] are more likely to be associated with post-evolution characters than names containing [i], and (4) names containing coronal consonants are more likely to be associated with post-evolution characters than names containing labial consonants. Overall, the current results suggest that phonological considerations come into play when English speakers name new fictional creatures. Implications of the current results for the theories of sound symbolism are discussed throughout the paper.

An experiment showed that Japanese speakers' judgement of Pokémons' evolution status on the basis of nonce names is affected both by mora count and by the presence of a voiced obstruent. The effects of mora count are a case of counting cumulativity, and the interaction between the two factors a case of ganging-up cumulativity. Together, the patterns result in what Hayes (2020) calls 'wug-shaped curves', a quantitative signature predicted by MaxEnt. I show in this paper that the experimental results can indeed be successfully modelled with MaxEnt, and also that Stochastic Optimality Theory faces an interesting set of challenges. The study was inspired by a proposal made within formal phonology, and reveals important previously understudied aspects of sound symbolism. In addition, it demonstrates how cumulativity is manifested in linguistic patterns. The work here shows that formal phonology and research on sound symbolism can be mutually beneficial.

Perceptual epenthesis is the perception of illusory vowels in consonantal sequences that violate native phonotactics. The consensus has been that each language has a single, predictable candidate for perceptual epenthesis, that vowel which is most minimal (i.e., shortest and/or quietest). However, recent studies have shown that alternate epenthetic vowels can be perceived when the perceptual epenthesis of the minimal vowel would violate native co-occurrence restrictions. We propose a potential explanation for these observed patterns: speech perception, and thus also vowel perceptual epenthesis, is modulated by transitional probability whereby epenthetic vowels must conform to the language specific expectations of the listener. To test this explanation, we present two experiments examining perceptual epenthesis of two Japanese vowels—/u/ and /i/—against their transitional probability in CV sequences. In Experiment 1, Japanese listeners assigned VCCV tokens to VCuCV and VCiCV categories. In Experiment 2, participants discriminated VCCV tokens from VCuCV and VCiCV tokens. The results show that sequences where /i/ is transitionally probable are more likely to elicit /i/ perceptual epenthesis.

From modern perspectives, these statements can be understood as an assertion about sound symbolism, i.e., systematic connections between sounds and meanings. Inspired by these writers, this article reports on an experiment that tests a sound symbolic value of sibilants. The experiment is a case study situated within the Pokémonastics research paradigm, in which the researchers explore the sound symbolic patterns in natural languages using Pokémon names. The current experiment shows that when presented with pairs of a flying-type Pokémon character and a normal-type Pokémon character, Japanese speakers are more likely to associate the flying-type Pokémons with names that contain sibilants than those names that do not contain sibilants. As was pointed out by Socrates, the sound symbolic connection identified in the experiment is likely to be grounded in the articulatory properties of sibilants – the large amount of oral airflow that accompanies the production of sibilants. Various implications of the current experiment for the sound symbolism research are discussed throughout the article.

However, the cross-modal relationship between linguistic sounds and motions (i.e., motion-sound symbolism) is an extremely understudied area of research. Against this background, this paper examines the cross-modal correspondences between categories of consonants on one hand and different acceleration profiles of motion stimuli on the other. In the two experiments that we conducted, we mechanically manipulated the acceleration profiles of the stimuli while holding the trajectory paths constant, thus distinguishing the effect of acceleration profiles from that of motion path shapes. The results show that different acceleration profiles can be associated with different types of consonants; in particular, movements with acceleration and deceleration tend to be associated with a class of sounds called obstruents, whereas movements without much acceleration tend to be associated with a class of sounds called sonorants. Moreover, the current experiments show that this sort of cross-modal correspondence arises even when the stimuli are not presented visually, namely, when the participants’ hands were moved passively by a manipulandum. In conclusion, the present study adds an additional piece of evidence demonstrating that bodily action-based information, i.e., proprioception as a very feasible candidate, could lead to sound symbolic patterns.

There has been a dramatic rise of interest in sound symbolism, systematic associations between sounds and meanings. Despite this, one aspect that is still markedly under-explored is its cumulative nature, i.e., when there are two or more sounds with the same symbolic meaning, whether these effects add up or not. These questions are important to address, since they bear on the general question of how speakers take into account multiple sources of evidence when they make linguistic decisions. Inspired by an accumulating body of research on cumulativity in other linguistic patterns, two experiments on sound symbolism using Pokémon names were conducted with native speakers of English. The experiments tested two types of cumulativity: Counting cumulativity, which holds if the effects of multiple instances of the same factor add up, and ganging-up cumulativity, which holds when the effects of different factors add up. The experiments addressed whether these patterns of cumulativity hold in sound symbolism, and, more importantly, if so, how. We found that (1) three factors can show ganging-up cumulativity, (2) counting cumulativity and ganging-up cumulativity can coexist in a single system, (3) ganging-up cumulativity patterns can plausibly be considered to be linear, and (4) counting cumulativity effects can be sub-linear.

Voice quality differences [1] can convey different attitudes and emotions [2], with speakers of different languages showing different sensitivities to voice qualities, e.g., [3, 4, 5]. It remains to be explored, however, precisely which acoustic properties are perceptually associated with what emotional meanings, and whether such perceptual mappings hold universally or differ across languages. This paper offers a first step addressing these issues. Building upon the previous findings that speakers of different languages demonstrate different sensitivities to voice quality differences, the study examines particularly how the perceptions of arousal and valence are affected by different voice qualities. The current experiment reveals that speakers of the three language groups share similar ratings of arousal in association with breathy voices. Yet the valence ratings vary among the groups: Japanese and Mandarin listeners rate voices with high F0 and small OQ with positivity, whereas Brazilian Portuguese rate voices with low F0 and larger OQ with positivity. The findings of this study have applications for second language teaching, and carry over to the worlds of business, politics, and advertisement; in general, this type of research may have a potential to be useful for improving communication in cross-cultural inter-personal relationships.
