discussion units (total number of the ones who are able to hold a speech synchronously
(exclude chairman units), we just call it “speech capacity” in the following content). And
Mode determines what the discussion unit can do when reaches at the maximum
speech capacity or not.

The following content will show you the detailed information about speech capacity and
speech mode.
