wav2vec2-base_down_on
This model is a fine-tuned version of facebook/wav2vec2-base on the MatsRooth/down_on dataset. It achieves the following results on the evaluation set:
- Loss: 0.1385
- Accuracy: 0.9962
Model description
Binary classifier using facebook/wav2vec2/base for the words "down" and "on".
Intended uses & limitations
This is a demo of binary audio classification that illustrates data layout, training and evaluation using python and slurm.
Training and evaluation data
The data are utterances of "down" and "on" in superb ks. See down_on_copy.py for the subsetting. This puts wav files in locations
like down_on/data/train/on and down_on/data/train/down
