result	object	Scoring result
- wavetime	number	Audio duration (Unit:milliseconds)	For reference
- conf	number	Confidence score. The matching degree between the recognized reading content and an answer branch in the text passed to the kernel. The threshold is set by the application layer to determine whether the result is correct (generally 75, which can be adjusted up and down according to the difficulty of the question).	Suggest to display
- rec	string	Recognized text branch.	Suggest to display
- overall	number	The overall score for evaluating the identified branch options.	Suggest to display
- integrity	number	Score of integrity.	Suggest to display
- accuracy	number	Score of accuracy(pronunciation evaluation of the read part).	For reference
- fluency	object	Fluency score details
- - overall	number	Overall score of fluency	Suggest to display
- - pause	number	Number of pauses.	Suggest to display
- - speed	number	Speech rate, which is the number of words read per minute.	Suggest to display
- starttime	number	Start time of pronunciation, in milliseconds (ms)	For reference
- endtime	number	End time of pronunciation, in milliseconds (ms)	For reference
- recscore	object	Need to configure the keyWords field, see the parameter description above for details.
- - status_code	number	The returned result and description are as follows: 20000:Pass 20002 :User voice content only contains part of keywords. 20003:The user's answer is completely irrelevant, and it is recommended that the application layer prompt the user to answer again. Notes：If the conf value is less than 55 points, the status_code here in recscore is set to 20003, and mathed field will be empty.	Suggest to display
- - matched	string	When the return code is 20000、20002, the matched keywords are also returned.	Suggest to display

Note: The other returned parameters that are not shown above are internal ones, which you don't need to pay much atttention to.

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.。
