Default Sync detectors and fading

Beyond a certain point, you get conflict. Have a scheme that does
a really good job of eliminating the fading, and likely that starts
affecting the "fidelity" of the signal, because how do you discriminate
between the voice at the transmitter end varying in amplitude, because
the speaker starts talking more quietly or even just because sounds are
made up of varying levels, and the signal fading as it travels to the
receiver? It's easy to counter some of the fading, but it gets harder
the more you try to conquer it.

Has anyone tried to measure the fading of the carrier and use that as a
guide as to whether the level change in the sideband is fading related
or program content related?
