30 Training Context Dependent models

Every BW step had 2 ERROR messages and 1 WARNING messages.

And you said it can be ignored .  But

 50 Training Context dependent models

BW step had 2 ERROR messages and 1 WARNING messages;

But norm step:

Some of this steps cound have up to 2116 ERROR messages and 0 WARNING messages.

Ignore them as well. The reason of the problem is that you are trying to train 1000 senones on a small amount of data. Either use more training data or lower the amount of senones in config file.

Thanks for you help.

And I set senones=500,then I got SE:50.6%,WE: 14.9%

In the process of Training , the Errors were down to 184(the most)

The core thing in ASR is that error always present. You can't be 100% sure you recognized correctly, you can only get some probability. That's why speech interfaces always use confidence and cross referencing to setup agreement between human and the system. Of course, you coudn't rely on recognition result.

For performance rate you can reach, everything depends on the size and the complexity of the vocabulary. Typical error rate for digits is 0.5%, for large vocabulary it's around  15-25%.
