A three tone test, where two normally spaced tones are measured
and modulated by a variation at a non-coherent syllabic rate, would
be best.
Remember the supplies are very much stabilized at frequencies
over a few dozen Hz by the capacitors that remove ripple, while the
voice will move them around at a much slower rate.
