DoReCo was a French-German collaborative project that brought together spoken language corpora from about 50 languages, extracted from documentations of small and often endangered languages. This resource was used for cross-linguistic research on phonetic lengthening processes and on information rate, and was made available for other research.

DoReCo started in March 2019 and ended in August 2022. If you have any questions please contact us at
