Field Documentation

boolean Recog::process_active

Status flag indicating whether the recognition is alive or not.

If TRUE, the process is currently activated, either monitoring an audio input or recognizing the current input. If FALSE, the recognition is now disabled until some activation command has been arrived from client. While disabled, all the inputs are ignored.

If set to FALSE in the program, Julius/Julian will stop after the current recognition ends, and enter the disabled status.

boolean Recog::process_want_reload

If set to TRUE, Julius/Julian stops recognition softly.

If it is performing recognition of the 1st pass, it immediately segments the current input, process the 2nd pass, and output the result. Then it enters the disabled status.
