Hi! Could you please copy & paste the connection error you get? To work with the local data, you’ll have to download the librispeech script from our repo and modify it in the way it reads the data from the downloaded directory - you can pass the path to the data directory as follows:
from datasets import load_dataset
dset = load_dataset("path/to/dir/of/your/modifiedlibrispeech/script", data_dir="path/to/librispeech/data")

and access the data_dir value in the modified librispeech script as follows:
def _split_generators(self, dl_manager):
    local_data_path = dl_manager.manual_dir
    ...
