Created in 1972, the Laboratoire Parole et Langage (LPL) is a joint research unit affiliated to both the CNRS and Aix-Marseille Université. Its members include phoneticians, linguists, computer scientists, psychologists, neuroscientists, physicists and medical practitioners.

The LPL's activities focus on the mechanisms involved in the production, perception and understanding of spoken and written language in their natural contexts.
In this field, the LPL is one of the major research labs in France and Europe.

The LPL hosts a shared experimental platform for the collection and analysis of data for the study of speech production and perception : Centre d’Expérimentation sur la Parole (CEP). It is designed for the collection of audio/video, as well as physiological and cerebral data. The platform includes a wide range of technical equipment on a surface of 150 sqm : Anechoic chamber, computerized devices for visual and auditory perception tests, electromagnetic articulograph system (EMA), voice analysis device (EVA), Biopac speech motor control, eye-tracking systems (Eyelink and Tobii), electroencephalograpjic systems (EEG and EGI). With its extensive range of research equipment, the CEP is unique in Europe.

The LPL is in charge of the Speech & Language Data Repository (SLDR), a Trusted Data Repository recognized as a CLARIN-C Center since 2015. It offers research laboratories and scholars a free-of-charge service for the deposit, sharing and archiving of their oral/linguistic material in compliance with the OAIS model. Resources include corpora, annotations, lexicons and other knowledge bases, as well as research tools applicable to such data. Ressources and documents are labelled with persistent identifiers facilitating their access regardless of location and status. As part of the development of the ORTOLANG platform, this secure storage procedure uses the servers of the INIST (Institut de l’information scientifique et technique) and long-term preservation is realized through the CINES (Centre informatique national de l’enseignement supérieur).
The Equipex ORTOLANG is a national project for sharing linguistic data. It completes the TGIR Huma-Num and brings together the experience and resources of the SLDR, for oral data, and CNRTL, for written data.

In 2012, the LPL became one of the leading members of the Brain and Language Research Institute. The Labex BLRI is a consortium which comprises seven high level research units and an extraordinary network of experimental platforms (CREX). It brings together multidisciplinary expertise in linguistics, computer science, psychology, neuroscience as well as medicine, thereby assembling all the expertise necessary for studying language processing as well as language’s foundations in the brain. The goal is to develop a generic and integrated model of language that can be computationally simulated.

The laboratory’s library contains more than 30,000 documents divided equally between two distinct collections: The Language Sciences collection contains specialized linguistic documents on phonetics, phonology, prosody, morphology, syntax, semantics and pragmatics, as well as on computer science, psychology, the neurosciences and medicine. The Creole collection, the largest collection of its kind in the world, was added to the laboratory’s library in 2002. It contains an almost exhaustive collection of documents on French-based Creole languages (history, language, literature, religion, society and culture). It also contains a substantial collection relating to linguistic development in French-speaking nations (particularly African and Creole regions). Furthermore, the library joined the Aix-Marseille University (AMU) library network in 2015 and the migration of LPL catalogue files to the AMU catalogue and the French union catalogue SUDOC for Higher Education and Research institutions has begun.
