To verify the accuracy of the validation, we developed a speech recognition model based on a version of NVIDIA-NeMo`s Parakeet, which does not have an official Spanish version. Our final model achieved a WER of less than 4{\%} on the test and validation splits of Common Voice 17.0. Both the model and the speech corpus are publicly available on Hugging Face."
