 # 🌍 African Digits Recording Sprint
+Existing speech recognition systems do not support ANY African languages, excluding African speakers from voice-enabled devices. Our voice is our identity!
+And so the goal of the project is to make a simple digits dataset for African languages through crowd-sourcing. You can easily teach a model to recognise numbers in your language using this dataset.
