Properties

authorizationToken

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

The authorization token used to communicate with the conversation transcription 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.
