I had use AIshell-1 train an ASR model
But I find out that it had bad performance when i give some audio noise as input
(I except to get blank as output, but it’s not)
I try to add some noises as training data, but i don’t know how to label it
it will get error when i just give blank space as labeled
My question is
- Can i labeled blank ?
- Any other solution can improve background noises as input?
