usted Effect
There are loud environment
noises.
Increase the maximum
amplitude of comfortable noises.
Too large amplitude might make noises
uncomfortable.
A user hears his or her voice
when speaking.
Enlarge the control factor of
mixed proportion of noises.
Too high a control factor leads to audio
discontinuity.
There are echoes when both
parties speak at the same time.
Enlarge the judgment threshold
for bidirectional conversation.
Too high a judgment threshold slows
down the convergence of the filter
factor.
Enabling the nonlinear function of echo cancellation
The nonlinear function of echo cancellation, also known as residual echo suppression, means the
removal of residual echoes after echo cancellation when the user at the local end does not speak.
