Suggestions for handling scoring results

Firstly, it is judged whether the value of the conf field exceeds the set threshold. If it exceeds, the content of the rec field is extracted, that is, the branch text read by the user is recognized this time. Otherwise, the user is prompted to try to read aloud again or not hear your pronunciation clearly.
