+# afrospeech-wav2vec-run
+
+This model is a fine-tuned version of [facebook/wav2vec2-base](https://huggingface.co/facebook/wav2vec2-base) on the [crowd-speech-africa](https://huggingface.co/datasets/chrisjay/crowd-speech-africa), which was a crowd-sourced dataset collected using the [afro-speech Space](https://huggingface.co/spaces/chrisjay/afro-speech). It achieves the following results on the [validation set](VALID_rundi_run_audio_data.csv):
+
+- F1: 0.8
+- Accuracy: 0.8
+
+The confusion matrix below helps to give a better look at the model's performance across the digits. Through it, we can see the precision and recall of the model as well as other important insights.

+
+## Training and evaluation data
+
+The model was trained on a mixed audio data from Rundi (`run`).
+
+- Size of training set: 16
+- Size of validation set: 5
