Properties

authorizationToken

@property (readonly, copy, nonatomic) NSString * _Nullable authorizationToken;

Authorization token used to communicate with the conversation translation service.

Note: The caller needs to ensure that the authorization token is valid. Before the authorization token expires, the caller needs to refresh it by calling this setter with a new valid token. Otherwise, the recognizer will encounter errors during recognition.

participantId

@property (readonly, copy, nonatomic) NSString * _Nullable participantId;

Participant identifier used for conversation translation.
