I think it depends on the voice spectrum. With a typical male voice there is a lot of power at low frequencies which is not needed for comprehension.
If those low frequencies are filtered out, either by an audio high-pass filter (series capacitor) or by the crystal filter (the edge nearest the carrier) then the extra transmitted bandwidth should make very little difference in "talk power".
