The JPC are biennial conferences of international scope. They are renowned and considered major events in the fields of voice, language and speech, whether in medical, developmental or social terms. The main aim of these multidisciplinary days is to bring together and encourage exchanges between researchers, clinicians, phoneticians and any other professionals interested in the mechanisms of speech production and perception. The JPC welcomes experts, young researchers and students from the clinical (medicine, speech therapy, audiology), psychological and language science fields. They deal with everything to do with language and voice in children and adults, whether healthy or suffering from a pathology. These aspects are approached from a variety of viewpoints, enabling us to share knowledge and open up new avenues for reflection, research and collaboration.
