Difference between the default command and the undo default command
The default command (such as the default entity vad-on command) is used to
configure default values for parameters of voice entities globally.
The undo default command is used to restore the global parameters to the fixed
system defaults.
The command command is used to configure voice parameters of a voice entity
as the specified values without changing the global values. Using the undo
command command restores for a voice entity the default values (that is, values
specified by the default command), without changing the global values.
The values of each parameter in different stages by using the default and undo
default commands are described below in detail.
1 Take the system fixed parameter value A by the command command as the
default value of default, and configure voice entity 1 with parameter B, voice
entity 2 with the default A and voice entity 3 with parameter C.
