Responses to Recognition Results

After receiving the continuous audio data from the client, the server sends the recognition results back by sentence in real time. The result responses (JSON character strings) are put in text messages.

Response

**Table 1** Response parameters
Parameter	Type	Description
resp_type	String	Response type. The value of this parameter is RESULT, indicating the recognition result response.
trace_id	String	Service internal token used to trace a specific process in logs
segments	Array of objects	Result of multiple segments. For details, see Table 2.

**Table 2** **segment** data structure
Parameter	Type	Description
start_time	Integer	Relative timestamp, indicating the start of a sentence. The unit is millisecond (ms).
end_time	Integer	Relative timestamp, indicating the end of a sentence. The unit is millisecond (ms).
is_final	Boolen	Indicates whether the output is the final result. The value true indicates that the result is the final result, and the value false indicates that the result is a temporary intermediate result.
result	Object	If the calling is successful, this parameter indicates the recognition result. Otherwise, this parameter is invalid. For details, see Table 3.

**Table 3** **result** data structure
Parameter	Type	Description
text	String	Recognition result
score	Float	Confidence level of the recognition result. The value ranges from 0 to 1. The value is continuously updated during real-time recognition until the final result is returned. NOTE: The confidence level of the temporary result does not play a significant role. Do not overly depend on this value.
