Comment
Gain of the acoustic echo; used to achieve equal signal
levels at the comparator in case of direct coupling
sound, therefore representing the acoustic properties
of the telephone housing, microphone, and speaker;
can be calculated from a TCL measurement.
Additional delta gain as reserve for GAE and as level
shift for the comparator characteristic (in case of
speech).
Delta gain in case of noise.
Peak decrement of the acoustic echo in case of
speech; slope of the comparator characteristic used to
cover all echoes.
Peak decrement of the acoustic echo in case of noise.
Echo time for the acoustic echo; only effective in case
of different parameters for GDSAE/PDSAE ("S")
GDNAE/PDNAE ("N"); determines the period of time
the "S" parameters remain active after speech
recognition has stopped before the "N" parameters are
used.
