[Gqwert123]

Hi, sorry to disturbe you. When I use my own corpus. when I use the off-line model align the ctc path. Sone instance got this bug. So can you tell me how to solve this problem.

logit shape: (1220, 52) 59 52 Traceback (most recent call last): File "../../../espnet/bin/asr_recog.py", line 180, in <module> main(sys.argv[1:]) File "../../../espnet/bin/asr_recog.py", line 176, in main viterbi_decode(args) File "/espnet/asr/pytorch_backend/asr_recog.py", line 177, in viterbi_decode align = model.viterbi_decode(feat[0][0], y) File "/espnet/nets/pytorch_backend/e2e_asr_transformer.py", line 253, in viterbi_decode align = viterbi_align(logit, y)[0] File "/espnet/nets/viterbi_align.py", line 26, in viterbi_align

raise Exception("Number of expected symbols more than the time stamps"

Hi, viterbi alignment requires the length of utterance is larger than the length of the sentence. You can just skip the failed instances.
