Introduction
I have been a CNRS Researcher since 2003. My research focuses on the diversity of languages (especially at the phonological level), the origins of language(s), language complexity, and digital tools in the language sciences.

Chapter
The objective of this chapter is to render the concept of "transition" operative for studying the changes in ‘settlement systems’ as it is possible to observe them, on the local scale of a microregion as well as on that of the planet. Ever since modern man has existed, he has used the surface of the earth, moved on it, exploited its resources and e...

Language is universal, but it has few indisputably universal characteristics, with cross-linguistic variation being the norm. For example, languages differ greatly in the number of syllables they allow, resulting in large variation in the Shannon information per syllable. Nevertheless, all natural languages allow their speakers to efficiently encod...
Chapter
The Bantu expansion toward Southern and Eastern Africa is a complex and long-term phenomenon. Migrations occurred along different paths, often likely to bypass the rainforest, which was not suitable for Bantu’s farming. At the same time, diverse groups of forest foragers lived in the forest. It is established that Bantu and forest foragers came to...

Classically, in the bouba-kiki association task, a subject is asked to find the best association between one of two shapes–a round one and a spiky one–and one of two pseudowords–bouba and kiki. Numerous studies report that spiky shapes are associated with kiki, and round shapes with bouba. This task is likely the most prevalent in the study of non-...

As statistical approaches are getting increasingly used in linguistics, attention must be paid to the choice of methods and algorithms used. This is especially true since they require assumptions to be satisfied to provide valid results, and because scientific articles still often fall short of reporting whether such assumptions are met. Progress i...
Chapter
Complex systems are often defined on the basis of the interactions that take place between their constituents. This approach echoes the founding principles of structuralism in linguistics more than a century ago. It was indeed Ferdinand de Saussure, in his 1916 Cours de linguistique générale, who defined any language as a system whose building bloc...
Chapter
Complexity has attracted a great deal of attention in linguistics since 2001, at a rate that proportionally far exceeds its invocations in the field since Ferdinand de Saussure, the father of our discipline, in the early twentieth century. The number of books bearing complexity in their title is remarkable, suggesting that there may be an emergent...

The question of complexity, as in what makes one language more 'complex' than another, is a long-established topic of debate amongst linguists. Recently, this issue has been complemented with the view that languages are complex adaptive systems, in which emergence and self-organization play major roles. However, few students of the phenomenon have...
Article
Contradicting Saussure's arbitrariness of the linguistic sign, sound symbolism – the systematic association of sounds with meanings – is consistently found across languages. It may have offered a ground for our ancestors to develop an initial communication system, and later move toward symbolic signs. We tested sound symbolic associations in French...
Article
Full-text available
In their paper, Everett et al. (2016) stress how a shift could or should take place from autonomous linguistic forms to ecologically adaptive ones. This raises the issue of the meaning of ecology when it comes to languages, and to what the Greek root of this word— oikos , the house or the habitat—actually refers. Several authors have equated the e...
Article
Full-text available
In this paper, we propose a functional and cross-language perspective on the organization of phonological systems based on the notion of functional load (FL). Using large corpora, we quantitatively characterize the relationships between phonological components (segments, stress and tones) by estimating their role at the lexical level. In a first an...

Bioacousticians have argued that ecological feedback mechanisms contribute to shaping the acoustic signals of a variety of species and anthropogenic changes in soundscapes have been shown to generate modifications to the spectral envelope of bird songs. Several studies posit that part of the variation in sound structure across spoken human language...
Article
Full-text available
Recent research on speech rate (Pellegrino et al., 2011) has shown that languages differ in terms of syllable rate, and that these differences are compensated by the average amount of information carried by syllables. The more syllables a language needs to express a given amount of information, the higher its syllable rate tends to be. These result...

LAPSyD, the Lyon-Albuquerque Phonological Systems Database, is an online phonological database equipped with powerful query, mapping and visualization tools. It stems from the UPSID and WALS databases, enhanced with newly validated data not only covering segmental inventories but also syllable structures, stress and tonal systems. In its current ve...

The notion of functional load (FL) quantifies the role a phonological contrast plays in keeping words distinct in a given language. Several studies have emphasized its potential impact on language evolution and acquisition, and FL has repeatedly been mentioned as a useful tool to supplement phonological descriptions for more than seventy years. It...

:This article is a crosslinguistic investigation of the hypothesis that the average information rate conveyed during speech communication results from a trade-off between average information density and speech rate. The study, based on seven languages, shows a negative correlation between density and rate, indicating the existence of several encodi...

Since the work of André Martinet back in the 60’s [7], the notion of ‘economy’ has been accepted as one of the main principles underlying the organization of phonological inventories (hereafter PI). This principle, also named MUAF (‘Maximal Use of Available Features’) by John Ohala [8], states that PI are organized along a few phonetic dimensions t...

Que se passait-il dans la tête dans nos ancêtres ? Quelles pensées, quelles humeurs agitaient leur esprit ? Quels mécanismes cérébraux et psychologiques sous-tendaient leurs raisonnements, leurs émotions et leurs actions ? Répondre à de telles questions est le défi de l'archéologie cognitive, et une tentative pour mieux cerner l'Homme moderne en re...

symbols, understanding of abstract concepts, intention reading and attention sharing, the ability of imitation, and so on. While chimpanzees ,share a strikingly high ,degree ,of similarity ,with humans, the question about language origin become more intriguing: if chimpanzees are so close to humans in cognitive abilities and social behaviors, why c...

On the one hand, numerous hypotheses have been put forward to account for the emergence of language during the last million years of human evolution. On the other hand, a large majority of linguists considers that nothing can be said about past languages before 8,000 or 10,000 years in the past, given our current knowledge on modern languages. A la...

. At Eurocrypt '96, Coppersmith presented a novel application of lattice reduction to find small roots of a univariate modular polynomial equation. This led to rigorous polynomial attacks against RSA with low public exponent, in some particular settings such as encryption of stereotyped messages, random padding, or broadcast applications `a la...
