This dataset is the speechcommands dataset, formatted in the WebDataset format. WebDataset files are essentially tar archives, where each example in the dataset is represented by a pair of files: a WAV audio file and a corresponding JSON metadata file. The JSON file contains the class label and other relevant information for that particular audio sample. $ tar tvf wds-audio-train_0000000.tar|head -r--r--r-- bigdata/bigdata 19 2025-01-10 08:58 right_7e783e3f_nohash_1.json -r--r--r-- bigdata/bigdata 32044 2025-01-10 08:58 right_7e783e3f_nohash_1.wav -r--r--r-- bigdata/bigdata 16 2025-01-10 08:58 up_c79159aa_nohash_3.json -r--r--r-- bigdata/bigdata 32044 2025-01-10 08:58 up_c79159aa_nohash_3.wav -r--r--r-- bigdata/bigdata 18 2025-01-10 08:58 left_2b42e7a2_nohash_3.json -r--r--r-- bigdata/bigdata 32044 2025-01-10 08:58 left_2b42e7a2_nohash_3.wav -r--r--r-- bigdata/bigdata 18 2025-01-10 08:58 left_c79159aa_nohash_4.json -r--r--r-- bigdata/bigdata 32044 2025-01-10 08:58 left_c79159aa_nohash_4.wav -r--r--r-- bigdata/bigdata 18 2025-01-10 08:58 left_708b8d51_nohash_0.json -r--r--r-- bigdata/bigdata 32044 2025-01-10 08:58 left_708b8d51_nohash_0.wav $ cat right_7e783e3f_nohash_1.json {"labels": "right"}
