Addis AI vs Meta (Facebook MMS)

MMS is a remarkable research release, and it does cover both languages. But the models are licensed CC-BY-NC-4.0, so you cannot use them commercially. The Amharic model cannot even read native Fidel script without Latin transliteration first, and there is no hosted API, no SLA, and no support.

Who Meta (Facebook MMS) is. Meta's Massively Multilingual Speech (MMS) project open-sourced text-to-speech checkpoints for 1,100+ languages, including Amharic (mms-tts-amh) and Afan Oromo (mms-tts-orm).

Where Addis AI fits. We are the voice and language model platform for African languages. Amharic and Afan Oromo are live today, fine-tuned for the languages, with more African languages on the way.
