cif-pytorch's Issues

ctc aligment loss?

Thers is a ctc aligment loss In "BOUNDARY AND CONTEXT AWARE TRAINING FOR CIF-BASED
NON-AUTOREGRESSIVE END-TO-END ASR"

How do you determine whether a ctc probs is a spike that exceeds the threshold using greedy search or a prefix beam search?

Question about cif

Only the boundary information in cif, but whether the silence or noise in the front will cause the accumulation of the first pronunciation to be particularly large

如何让训练cif_output的输出恰好等于target_length

非常感谢您提供的代码,但是我有一个小困惑,weight的sum等于target_length,为什么cif_output输出的长度与target_length不符,按照论文原理,应该恰好等于target_length,如果想要它刚好等于target_length,应该如何修改code呢
