Since 2006, the French linguist community has had a tool for depositing the sound sources that document the world’s linguistic diversity. Named Cocoon, for “COllections de COrpus Oraux Numériques”, this technical platform was then opened to all researchers wishing to create, structure, make accessible and archive sound corpora composed of audio recordings accompanied, in a third of cases, by annotations and transcriptions. It seemed to me that within the framework of Digital Orientalist, it is interesting to make this tool known. It is both elaborate in its conception and simple in its use.
