A Purely End-to-end System for Multi-speaker Speech Recognition
Table 1: Duration (hours) of unmixed and mixed corpora. The mixed corpora are generated by Algorithm 1 in Section B of the supplementary material, using the training, development, and evaluation set respectively.
['[EMPTY]', 'Train', 'Dev.', 'Eval']
We created new corpora by mixing two utterances with different speakers sampled from existing corpora. The sampled pairs of two utterances are mixed at various signal-to-noise ratios (SNR) between 0 dB and 5 dB with a random starting point for the overlap.
