zasr_tensorflow's Issues

执行run_data.sh时候报错

Creating manifest data/aishell/manifest ...
Traceback (most recent call last):
File "data_utils/build_vocab.py", line 19, in
from utils.utility import add_arguments, print_arguments
ImportError: No module named utility
Build vocabulary failed. Terminated.

貌似这个utils.utility找不到。
我尝试重新安装了utils和utility都没有效果,请问改怎么处理啊

关于解码的问题

Hanpei你好,
请问这个版本的代码目前都是可以跑通的吗?
我在运行这个代码的时候发现训练的时候输出的Transcript都是空的,是因为tf的ctc_decoder使用得有问题吗?
另外,运行python test.py的时候
使用lm_decode解码出来的结果也是乱码~

Is it possible that the downloaded file is really broken or the MD5 checksum itself is wrong? Thanks in advance.

请问准确率如何

请问下训练需要多长时间,准确率如何,可以分享训练好的模型出来吗,谢谢

语言模型

请问,目前的RNN-CTC是可以实现端到端的语音识别的,可以直接输出汉字,那这个模型里面有语言模型吗?如果没有是不是外加一个语言模型效果会不会有提升?如果可以,那么需要怎么外加语言模型?
