Build custom dataset to fine-tune Wav2Vec2
Thank you for your recent tutorial on how to finetune Wav2Vec2 on a custom dataset. The example you gave here (https://huggingface.co/blog/fine-tune-xlsr-wav2vec2) was on the CommonVoice dataset. However, what if I want to load my own dataset?  I have a manifest (transcript and their audio files) in a JSON file.
