Phonological Typology and Learnability

Description: 

Generative linguistics assumes that language learning is possible because the space of possible gram- mars (the typology) has non-trivial structure that can be exploited by a learner. What is this structure? Within the framework of constraint-based phonology, the typology is defined through a substantive theory of the phonological constraints plus a formal theory of their mode of interaction. Learnability guarantees have so far been derived from formal properties of the mode of constraint interaction, with- out substantive phonological assumptions about the constraints. Our project charts the limits of this ”substance-free” approach and lays the foundations of a new ”substance-full” alternative. The complex- ity of various subcomponents of the learning problem is probed through intractability results, showing that these tasks are too hard for a learner to succeed, if (s)he uses only the structure provided by the mode of constraint interaction. Additional structure is needed, provided by phonologically substantive and typologically supported restrictions on the constraints (whether innate or induced). We focus on three phenomena: variation, chain-shifts, and segmental phonotactics. Which constraint theories account for the typological restrictions observed in these three phenomena? How can the learnability implications of these substantial constraint theories be extracted? We aim at analytical guarantees, rather than just simulation results. The complementarity between the phonological expertise of the MIT team and the learnability expertise of the French team will allow our project to break new ground in the learnability of phonology, developing the generative axiom of a connection between learnability and typology to a new level of mathematical sophistication.

The Mathematics of Language Universals

Description: 

The question of language universals is central to cognitive sciences but still controversial. The universalist view holds that all languages are deeply similar and that identifying their universal properties is the subject mat- ter proper of linguistics. The anti-universalist view holds that languages differ in arbitrary ways and whatever languages seem to share is due to accidents of their history. Language universals have so far been studied inductively, by surveying the world’s languages, cataloguing phenomena, and observing systematic gaps. However, deriving language universals in a systematic and principled manner remains a largely unsolved problem. The difficulty is compounded by the fact that many interesting universals are statistical, making their direct induction particularly challenging. Our project will thus lay the foundation of a new indirect approach to language universals, whereby (1) candidate universals are derived formally from (categorical and stochastic) linguistic models through a sophisticated mathematical analysis of their “geometry” and then (2) validated on large databases of the world’s languages. By combining expertise in mathematical linguistics (French team) with expertise in theoretical and large-scale typological linguistics (Stanford team), the project promises to break new ground on the central question of the place of language in human cognition.

MathSegPhon

Description: 

MathSehPhon: The mathematics of segmental phonotactics

The goal of this project is to understand the formal properties which shape segment inventories cross-linguistically and to investigate their learnability implications. The project tackles questions such as the following: what is the proper format of the feature co-occurrence constraints which shape segment inventories? Do these constraints satisfy formal restrictions? What are the learnability implications of these restrictions? What are the implications of the classical Richness of the Base assumption? What is the role of contrast in shaping consonant inventories? And how should contrast be properly formalized?

SignAge

Description: 

SignAge : Variation en LSF et vieillissement : recueil exploratoire d’interactions entre signeurs âgés avec données augmentées (vidéo et biomécaniques)

SignAge est un projet de recueil (vidéo et capture de mouvements, en dispositif mobile) et d’étude d’interactions entre et avec des signeurs âgés (+65ans) pour éprouver une méthodologie de recueil adaptée à l’exploration des éventuels marqueurs du vieillissement (typique, et atypique à plus long terme) en langue des signes (la LSF en France), notamment dans leurs dimensions articulatoire, prosodique et pragmatique. Il bénéficie d'un financement AAP 2017. En partenariat avec Dominique Boutet (Université de Rouen), Laurence Meurant (Namur), Anne-Marie Parisot (Montréal), Guillaume Duboisdindien (Nanterre), Marie-Anne Note, Natacha Hébert et la SCOP d'interpretation LIESSE.

IntonaSigne : capture de mouvements et analyse prosodique de la LSF

IntonaSigne est un projet d’étude exploratoire de la prosodie en LSF (langue des signes française) qui vise i) à obtenir des données augmentées, notamment grâce à la capture de mouvement, ii) à dresser un inventaire des paramètres et mesures biomécaniques pertinents pour cette analyse prosodique et iii) à exploiter ces mesures dans le cadre de l’analyse prosodique de corpus en langue(s) des signes et de leur traduction en langue vocale. Il bénéficie d'un financement AAP 2018-(renouvelable deux fois).

En partenariat avec Dominique Boutet (Université de Rouen), Laurence Meurant (Université de Namur), Anne-Marie Parisot (UQAM, Montréal).

FSDet

Description: 

On the phonology-morphosyntax interface in child and adult learners of French - The development of determiners and consequences for left edge phenomena

The aim of this project is to investigate the developmental relationship between phonology, prosody and morphosyntax in the acquisition of French by mono- and bilingual children (Swedish-French) and adult second language learners (L1 Swedish). The focus will be on the emergence of the determiner system and a number of properties related to determiners.
