 Evaluation on the full test set:
 - takes ~20mins (RTX 3090).
-- requires ~170GB RAM to compute the WER. A potential solution to this is computing it in chunks.
-  See https://discuss.huggingface.co/t/spanish-asr-fine-tuning-wav2vec2/4586/5 on how to implement this.
+- requires ~170GB RAM to compute the WER. Below, we use a chunked implementation of WER to avoid large RAM consumption.
