DONDO ships 26 Apache-2.0 speech models covering 27 African language varieties at 10-13% WER.

Paul Azunre released twenty-one monolingual and five multilingual w2v-BERT 2.0 ASR base models spanning varieties across Ghana, Sierra Leone, Nigeria, Senegal, Kenya, and Zimbabwe, languages with roughly a hundred million first-language speakers (arXiv 2607.21540). An annealed multi-step learning-rate schedule plus language conditioning via one-hot language identity prefixed to acoustic features brings the five multilingual families to 10-13% average WER, closing most of the gap to monolingual. Apache-2.0 attribution-only on the Hugging Face KhayaAI org, so commercial fine-tuning is permitted. Caveat: training data is primarily religious text, which constrains domain coverage hard.
