Exploiting the speech-gesture link to capture fine-grained prosodic prominence impressions and listening strategies

Published in Journal of Phonetics, 2019

In this paper, we explore the possibility to gather perceptual impressions of prosodic prominence by exploiting the strong prosody-gesture link, i.e., by having listeners transform a perceptual impression into a motor movement, namely drumming, for two domains of prominence: word-level and syllable-level. A feasibility study reveals that such a procedure is indeed easily and speedily mastered by naïve listeners, but more difficult for word-level prominences. We furthermore examine whether “drummed” annotations are comparable to those gathered with more established annotation protocols based on cumulative naïve impressions and fine-grained expert ratings. These comparisons reveal high correspondences across all prominence annotation protocols, thus corroborating the general usefulness of the gestural approach. The analyses also reveal that all annotation protocols are strongly driven by structural linguistic considerations. We then use Random Forest Models to investigate the relative impact of signal and structural cues to prominence annotations. We find that expert ratings of prosodic prominence are guided comparatively more by structural concerns than those of naïve annotators, that word-level annotations are influenced more by structural linguistic cues than syllable-level ones, and that “drummed” annotations are driven least by structural cues. Lastly, we isolate two main listener strategies among our group of “drummers”, namely those integrating structural and signal cues to prominence, and those being guided predominantly by signal cues.

Iconic prosody is rooted in sensori-motor properties: Fundamental frequency and the vertical space

Published in CogSci 2019, 2019

The iconic cross-modal correspondence between fundamental frequency and location in vertical space (“high is up”) has long been described in the literature. However, an explanation for this relationship has not been proposed. We conducted an experiment in which participants shot at cans projected on the wall in different vertical positions. We found that mean fundamental frequency was significantly influenced by vertical head position. Moving the head upwards changes the position of the larynx, which pulls on the cricothyroid muscle and changes the fundamental frequency. We thus propose that the iconic relationship between fundamental frequency and vertical space is grounded in the body.

Hand-Mouth Coordination in a Pointing Task Requiring Manual Precision

Published in Proceedings of the 12th ISSP, 2020

In daily life, articulatory movements and pointing gestures are tightly coupled. Nevertheless, the two motor systems governing the movements of the articulators and hands differ in their dynamics: the articulators are fast and much lighter than the limbs, which are slower due to their mass. We investigated the timely coordination of those motor systems in a pointing task requiring manual precision. In our experiment, the initial segment was always [p], allowing the participants for early articulatory preparation. Most importantly, we found that the hand gesture onset precedes the onset of the articulatory gesture. We also found that some speakers begin the articulatory movement only after reaching the hand gesture target. Overall, our data reveal that when the articulatory movement is not audible, as it is the case of [p], speakers are very flexible in the coordination between hand and mouth.

Novel vocalizations are understood across cultures

Published in Scientific Reports, 2021

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.

A cross-linguistic, sound symbolic relationship between labial consonants, voiced plosives, and Pokémon friendship

Published in Frontiers in Psychology, 2023

This paper presents a cross-linguistic study of sound symbolism, analysing a six-language corpus of all Pokémon names available as of January 2022. It tests the effects of labial consonants and voiced plosives on a Pokémon attribute known as friendship. Friendship is a mechanic in the core series of Pokémon video games that arguably reflects how friendly each Pokémon is. Poisson regression is used to examine the relationship between the friendship mechanic and the number of times /p/, /b/, /d/, /m/, /g/, and /w/ occur in the names of English, Japanese, Korean, Chinese, German, and French Pokémon. Bilabial plosives, /p/ and /b/, typically represent high friendship values in Pokémon names while /m/, /d/, and /g/ typically represent low friendship values. No association is found for /w/ in any language. Many of the previously known cases of cross-linguistic sound symbolic patterns can be explained by the relationship between how sounds in words are articulated and the physical qualities of the referents. This study, however, builds upon the underexplored relationship between sound symbolism and abstract qualities.

Random forests, sound symbolism and Pokémon evolution

Published in PLOS One, 2023

This study constructs machine learning algorithms that are trained to classify samples using sound symbolism, and then it reports on an experiment designed to measure their understanding against human participants. Random forests are trained using the names of Pokémon, which are fictional video game characters, and their evolutionary status. Pokémon undergo evolution when certain in-game conditions are met. Evolution changes the appearance, abilities, and names of Pokémon. In the first experiment, we train three random forests using the sounds that make up the names of Japanese, Chinese, and Korean Pokémon to classify Pokémon into pre-evolution and post-evolution categories. We then train a fourth random forest using the results of an elicitation experiment whereby Japanese participants named previously unseen Pokémon. In Experiment 2, we reproduce those random forests with name length as a feature and compare the performance of the random forests against humans in a classification experiment whereby Japanese participants classified the names elicited in Experiment 1 into pre-and post-evolution categories. Experiment 2 reveals an issue pertaining to overfitting in Experiment 1 which we resolve using a novel cross-validation method. The results show that the random forests are efficient learners of systematic sound-meaning correspondence patterns and can classify samples with greater accuracy than the human participants.

Is gesture-speech physics at work in rhythmic pointing? Evidence from Polish counting-out rhymes

Published in Proceedings of the 20th International Congress of Phonetic Sciences, 2023

Gesture-speech physics’ refers to a possible biomechanical coupling between manual gesture and speech. According to this thesis, rapid gesturing leaves a direct imprint on acoustics (intensity, F0), as gesture accelerations/decelerations increase expiratory forces and therefore subglottal pressure, leading to higher amplitude envelope peaks and higher F0 values. This acoustic effect has been reported in lab experiments, spontaneous speech, clinical studies, and professional vocal performers. The current study investigates this phenomenon in Polish counting-out rhymes, using motion capture data and acoustic recordings from 11 native Polish speakers. Following the gesture-speech physics thesis, we expect acceleration/deceleration peaks to be correlated with speech intensity/F0. Through Bayesian analyses, we obtained a weak but reliable coupling of deceleration of the pointing hand and the nearest peak in the smoothed amplitude envelope.

Iconicity in Language (WiSe 2018/2019)

Bachelor's seminar, Humboldt-Universität zu Berlin, Sprach- und literaturwissenschaftliche Fakultät, 2018

Course description:
According to de Saussure (1916), arbitrariness is one of the fundamental principles of a linguistic sign. A theory that is often cited in opposition to the Saussurian view is iconicity, which according to Perniss & Vigliocco (2014, 2) means “any resemblance between certain properties of linguistic/communicative form […] and certain sensori-motor and/or affective properties of corresponding referents”. For almost 100 years, new evidence in favor of iconicity in language has been presented again and again. In this course, we will explore the question of whether arbitrariness and iconicity can coexist in languages and according to which principles iconicity can occur. In the first part, we will look at previous research on iconicity and then carry out our own empirical work in the second part.

Sound symbolism (SoSe 2022)

Master's seminar, Humboldt-Universität zu Berlin, Sprach- und literaturwissenschaftliche Fakultät, 2022

Course description:
In linguistics studies, we learn that morphemes are the smallest units that carry meaning. But can sounds have a meaning? In this seminar, we will explore this question. We will look at linguistic iconicity at the level of sounds. We will look at the possibilities of sounds to create meaning across languages and within a language. We will also discuss why sound symbolism might be so important to our communication system. As participants, you will be encouraged to conduct your own experiments in groups based on previous research.
Prerequisites: Basic knowledge of phonetics and phonology, good command of English texts
Advantageous: Knowledge of Praat, statistical evaluation methods (with R)

Introduction to linguistics (WiSe 2023/24)

Bachelor's course, Humboldt-Universität zu Berlin, Sprach- und literaturwissenschaftliche Fakultät, 2023

Course description:
The course introduces students to the subject areas, questions and methods of linguistics. The focus is on the various levels of grammatical structure formation - phonology, morphology, syntax, semantics and the related sub-areas of phonetics, graphemics and pragmatics. Basic linguistic terms and concepts will be explained using traditional and modern methods of analysis based on the example of German and their interaction will be described. The approach will be characterized by a view of the cognitive foundations of language and the typological classification of German in the spectrum of the world’s languages.
