The Poio project develops language technologies to support communication in lesser-used and under-resourced languages on and with electronic devices. Within the Poio project we develop text input services with text prediction and transliteration for mobile devices and desktop users to allow conversation in hundreds of languages between individuals and in online communities. Poio started as a language revitalization project at the Interdisciplinary Centre for Social and Language Documentation in Minde/Portugal, a non-profit organization dedicated to the documentation and preservation of linguistic heritage.
