  • Simulating Early Phonetic and Word Learning Without Linguistic Categories

    Open AccessMarvin Lavechin, Maureen de Seyssel et al.ARTICLEDevelopmental Science2025

    Before they even talk, infants become sensitive to the speech sounds of their native language and recognize the auditory form of an increasing number of words. Traditionally, these early perceptual changes are attributed to an emerging knowledge of linguistic categories such as phonemes or words. However, there is growing skepticism surrounding this interpretation due to limited evidence of category knowledge in infants. Previous modeling work ha…

  • Modeling early phonetic acquisition from child-centered audio data

    Open AccessMarvin Lavechin, Maureen de Seyssel et al.ARTICLECognition2024

  • Modeling the initial state of early phonetic learning in infants

    Maxime Poli, Thomas Schatz et al.PREPRINT2024

    What are the necessary conditions to acquire language? Do infants rely on simple statistical mechanisms, or do they come pre-wired with innate capabilities allowing them to learn their native language(s)? Previous modeling studies have shown that unsupervised learning algorithms could reproduce some aspects of infant phonetic learning. Despite these successes, algorithms still fail to reproduce the learning trajectories observed in infants. Here,…

  • Modeling early phonetic acquisition from child-centered audio data

    Marvin Lavechin, Maureen de Seyssel et al.PREPRINT2023

    Infants learn their native language(s) at an amazing speed. Before they even talk, their perception adapts to the language(s) they hear. However, the mechanisms responsible for this perceptual attunement and the circumstances in which it takes place remain unclear. This paper presents the first attempt to study perceptual attunement using ecological child-centered audio data. We show that a simple prediction algorithm exhibits perceptual attuneme…

  • Realistic and broad-scope learning simulations

    Open AccessMaureen de Seyssel, Marvin Lavechin et al.ARTICLEJournal of Child Language2023

    There is a current 'theory crisis' in language acquisition research, resulting from fragmentation both at the level of the approaches and the linguistic level studied. We identify a need for integrative approaches that go beyond these limitations, and propose to analyse the strengths and weaknesses of current theoretical approaches of language acquisition. In particular, we advocate that language learning simulations, if they integrate realistic …

  • Statistical learning models of early phonetic acquisition struggle with child-centered audio data

    Marvin Lavechin, Maureen de Seyssel et al.PREPRINT2022

    Infants learn their native language(s) at an amazing speed. Before they even talk, their perception adapts to the language(s) they hear. However, the mechanisms responsible for this perceptual attunement still remain unclear. A long tradition in linguistics points to the importance of specialized language mechanisms that would allow us to quickly and effortlessly learn from the language(s) we are exposed to. However, the currently dominant explan…

  • Can statistical learning bootstrap early language acquisition? A modeling investigation

    Marvin Lavechin, Maureen de Seyssel et al.PREPRINT2022

    Before they even produce their first word, infants start developing a language-specific perception, recognize the auditory form of frequent words, and develop a rudimentary knowledge of grammatical categories. A major question in language development is: what mechanisms are responsible for the effortless learning infants demonstrate? In-laboratory experiments have shown that young infants are exquisitely sensitive to fine-grained statistical regu…

  • The effect of different information sources on prosodic boundary perception

    Open AccessBogdan Ludusan, Masahiro Morii et al.ARTICLEJASA Express Letters2021

    This study aims to quantify the effect of several information sources: acoustic, higher-level linguistic, and knowledge of the prosodic system of the language, on the perception of prosodic boundaries. An experiment with native and non-native participants investigating the identification of prosodic boundaries in Japanese was conducted. It revealed that non-native speakers as well as native speakers with access only to acoustic information can re…

  • SCALa

    Sho Tsuji, Alejandrina Cristia et al.PREPRINT2021

    Theories and data on language acquisition suggest a range of cues are used, ranging from information on structure found in the linguistic signal itself, to information gleaned from the environmental context or through social interaction. We propose a blueprint for computational models of the early language learner (SCALa, for Socio-Computational Architecture of Language Acquisition) that makes explicit the connection between the kinds of informat…

  • Does Infant‐Directed Speech Help Phonetic Learning? A Machine Learning Investigation

    Open AccessBogdan Ludusan, Reiko Mazuka et al.ARTICLECognitive Science2021

    A prominent hypothesis holds that by speaking to infants in infant-directed speech (IDS) as opposed to adult-directed speech (ADS), parents help them learn phonetic categories. Specifically, two characteristics of IDS have been claimed to facilitate learning: hyperarticulation, which makes the categories more separable, and variability, which makes the generalization more robust. Here, we test the separability and robustness of vowel category lea…

  • Reverse engineering language acquisition with child-centered long-form recordings

    Marvin Lavechin, Maureen de Seyssel et al.PREPRINT2021

    Language use in everyday life can be studied using lightweight, wearable recorders that collect long-form recordings - that is, audio (including speech) over whole days. The hardware and software underlying this technique is increasingly accessible and inexpensive, and these data are revolutionizing the language acquisition field. We first place this technique into the broader context of the current ways of studying both the input being received …

  • Do Infants Really Learn Phonetic Categories

    Open AccessNaomi H Feldman, Sharon Goldwater et al.ARTICLEOpen MIND2021

    Early changes in infants' ability to perceive native and nonnative speech sound contrasts are typically attributed to their developing knowledge of phonetic categories. We critically examine this hypothesis and argue that there is little direct evidence of category knowledge in infancy. We then propose an alternative account in which infants' perception changes because they are learning a perceptual space that is appropriate to represent speech, …

  • Segmentability Differences Between Child-Directed and Adult-Directed Speech

    Open AccessAlejandrina Cristia, Emmanuel Dupoux et al.ARTICLEOpen MIND2019

    Previous computational modeling suggests it is much easier to segment words from child-directed speech (CDS) than adult-directed speech (ADS). However, this conclusion is based on data collected in the laboratory, with CDS from play sessions and ADS between a parent and an experimenter, which may not be representative of ecologically collected CDS and ADS. Fully naturalistic ADS and CDS collected with a nonintrusive recording device as the child …

  • WordSeg

    Open AccessMathieu Bernard, Roland Thiollière et al.ARTICLEBehavior Research Methods2019

    A basic task in first language acquisition likely involves discovering the boundaries between words or morphemes in input where these basic units are not overtly segmented. A number of unsupervised learning algorithms have been proposed in the last 20 years for these purposes, some of which have been implemented computationally, but whose results remain difficult to compare across papers. We created a tool that is open source, enables reproducibl…

  • Early phonetic learning without phonetic categories -- Insights from large-scale simulations on realistic input

    Thomas Schatz, Naomi Feldman et al.PREPRINT2019

    Before they even speak, infants become attuned to the sounds of the language(s) they hear, processing native phonetic contrasts more easily than non-native ones. For example, between 6-8 months and 10-12 months, infants learning American English get better at distinguishing English [ɹ] and [l], as in ‘rock’ vs ‘lock’, relative to infants learning Japanese. Influential accounts of this early phonetic learning phenomenon initially proposed that inf…

  • Are Words Easier to Learn From Infant‐ Than Adult‐Directed Speech? A Quantitative Corpus‐Based Investigation

    Open AccessAdriana Guevara‐Rukoz, Alejandrina Cristia et al.ARTICLECognitive Science2018

    We investigate whether infant-directed speech (IDS) could facilitate word form learning when compared to adult-directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented before for phonemes, the realizations of words are more variable and less discriminable in IDS than …

  • Relating unsupervised word segmentation to reported vocabulary acquisition

    Elin Larsen, Alejandrina Cristia et al.PREPRINT2017

    A range of computational approaches have been used to model the discovery of word forms from continuous speech by infants. Typically, these algorithms are evaluated with respect to the ideal ’gold standard’ word segmentation and lexicon. These metrics assess how well an algorithm matches the adult state, but may not reflect the intermediate states of the child’s lexical development. We set up a new evaluation method based on the correlation betwe…

  • ASR Systems as Models of Phonetic Category Perception in Adults

    Thomas Schatz, Francis Bach et al.ARTICLE2017

    We test the potential of standard Automatic Speech Recognition (ASR) systems trained on large corpora of continuous speech as quantitative models of human speech processing. In human adults, speech perception is attuned to efficiently process native speech sounds, at the expense of difficulties in pro- cessing non-native sounds. We use ABX-discriminability measures to test whether ASR models can account for the patterns of confusion between speec…

  • The more, the better? Behavioral and neural correlates of frequent and infrequent vowel exposure

    Open AccessSho Tsuji, Paula Fikkert et al.ARTICLEDevelopmental Psychobiology2017

    A central assumption in the perceptual attunement literature holds that exposure to a speech sound contrast leads to improvement in native speech sound processing. However, whether the amount of exposure matters for this process has not been put to a direct test. We elucidated indicators of frequency-dependent perceptual attunement by comparing 5-8-month-old Dutch infants' discrimination of tokens containing a highly frequent [hɪt-he:t] and a hig…

  • Child-Directed Speech Is Infrequent in a Forager-Farmer Population

    Open AccessAlejandrina Cristia, Emmanuel Dupoux et al.ARTICLEChild Development2017

    This article provides an estimation of how frequently, and from whom, children aged 0-11 years (Ns between 9 and 24) receive one-on-one verbal input among Tsimane forager-horticulturalists of lowland Bolivia. Analyses of systematic daytime behavioral observations reveal < 1 min per daylight hour is spent talking to children younger than 4 years of age, which is 4 times less than estimates for others present at the same time and place. Adults prov…

  • Frequency & Compositionality in Emergent Communication

    Association for Computational Linguistics, Emmanuel Dupoux et al.

    In natural languages, frequency and compositionality exhibit an inverse relationship: the most frequent words often resist regular patterns, developing idiosyncratic forms. This phenomenon, exemplified by irregular verbs, raises a compelling question: do artificial communication systems follow similar principles? Through systematic experiments with neural network agents in a referential game setting, and by manipulating input frequency through Zi…

  • LongTail-Swap

    Association for Computational Linguistics, Robin Algayres et al.

    Children learn how to speak with a low amount of data and can be taught new words on a few-shot basis, which makes them particularly data-efficient learners. The BabyLM challenge aims at exploring language model (LM) training in the low data regime but uses metrics that concentrate on the head of the word distribution. Here, we introduce LongTail-Swap (LT-Swap), a benchmark that focuses on the tail of the distribution, i.e., measures the ability …

  • Coping With Linguistic Diversity

    Jacques Mehler, Emmanuel Dupoux et al.

    Because multilingual environments are the norm rather than the excep­ tion, infants must have the capacity very early in life to distinguish one language from another. Without such a capacity, infants might acquire linguistic systems that amalgamate properties of different languages. The ensuing confusion would be overpowering. Fortunately, this never arises, despite the intuitive fears of monolingual parents. Infants raised in multilingual socie…
