Value	Description
const unsigned long LSCOMPLETE_CAUSE_PROGRAMDISABLED = 1;	Listening mode was turned off by program code.
const unsigned long LSCOMPLETE_CAUSE_PROGRAMTIMEDOUT = 2;	Listening mode (turned on by program code) timed out.
const unsigned long LSCOMPLETE_CAUSE_USERTIMEDOUT = 3;	Listening mode (turned on by the Listening key) timed out.
const unsigned long LSCOMPLETE_CAUSE_USERRELEASEDKEY = 4;	Listening mode was turned off because the user released the Listening key.
const unsigned long LSCOMPLETE_CAUSE_USERUTTERANCEENDED = 5;	Listening mode was turned off because the user finished speaking.
const unsigned long LSCOMPLETE_CAUSE_CLIENTDEACTIVATED = 6;	Listening mode was turned off because the input active client was deactivated.
const unsigned long LSCOMPLETE_CAUSE_DEFAULTCHARCHANGE = 7	Listening mode was turned off because the default character was changed.
const unsigned long LSCOMPLETE_CAUSE_USERDISABLED = 8	Listening mode was turned off because the user disabled speech input.

This event is sent to all clients when the Listening mode begins after the user presses the Listening key or when its time-out ends, or when the input-active client calls the IAgentCharacterEx::Listen method with True or False.

The event returns values to the clients that currently have this character loaded. All other clients receive a null character (empty string).
