I’d suggest just adding common spelling errors to your training data tbh (if you’re using the tensorflow embedding pipeline)

@akelad here is pipline. There could be many errors during the typing, so should I put all the possible errors ? is not be duplication ?

eg: 1- i am hapy for being alone. 2- i am happyfor being alone. 3- i am thapy being a lone .

should I insert all of them in my training files ??
