Safaliba language
Safaliba is a Gur language of Ghana. A recent project has developed a writing system for the language in order to enable its use in  adult education and early school instruction. The Safaliba writing system is based on the work (1996) of Edmund Kuŋi Yakubu, a Safaliba teacher and activist; a few changes in that system were made by Paul and Jennifer Schaefer, based on their phonological work, but the writing system for the most part stayed the same. Safaliba audio recordings have been documented, transcribed, and discussed in Sherris, Schaefer, and Aworo (2018).
