DataTrust Africa: Speech Corpus of Public Radio Recordings from Northern Uganda

This is an open-access corpus of short clips of public radio content from Mega 100 FM, Q FM, Radio Pacis and Radio Rupiny in Northern Uganda. As of now, the online corpus has over 350 clips of recordings in English. We also hope to add finely-annotated transcripts to them. The dataset is for use in NLP research and non-commercial use. Upcoming datasets to look out for from Amara Hub are public radio recordings in other languages spoken in the region like Acholi, Lango, Lugbara and Akaramajong.
