Sub-Saharan African languages refers to the diverse group of indigenous languages spoken across the portion of the African continent situated south of the Sahara Desert. Representing thousands of distinct linguistic varieties across major families such as Niger-Congo, Nilo-Saharan, Afroasiatic, and Khoisan, these languages exhibit significant structural diversity, frequently featuring tone systems and complex noun classification systems. While spoken by hundreds of millions of people across highly multilingual societies, many of these languages are underrepresented in digital and computational technologies due to a historical scarcity of standardized orthographies, transcribed speech resources, and large-scale textual corpora.
