请问下训练效果怎么样呢? 以aishell-1 或者 librispeech 的实验结果?

我之前导出过 aut 头,接入CTC训练,但是一直不收敛。 您这边结果如何?

@shylockasr 哈喽,aishell1训练的结果如下,能收敛,但是结果比较差

Ctc greedy Ctc prefix
Aishell train 70epoch 14.67 % N=104765 C=96573 S=4798 D=3394 I=7179 14.21 % N=104765 C=96839 S=4866 D=3060 I=6961

您的结果跟我们一致, 3-omni 需要 decoder 部分辅助 encoder+ctc进行训练,不然会出现 精度很差的问题。
