AudioMNIST consists of audio recordings of 60 different speakers saying the digits 0 to 9, with 50 recordings per digit per speaker [1, 2]. The processed dataset contains 30,000 (univariate) time series, each of length 47,998 (approximately 1 second of data sampled at 44khz), with ten classes representing the digits 0 to 9. This version of the dataset has been split into cross-validation folds based on speaker (i.e., such that recordings for a given speaker do not appear in both the training and validation sets). AudioMNIST-DS is a variant of the same dataset downsampled to a length of 4,000.
