That is for UNPROCESSED speech (that is, no compression, peak limiting, AGC,
or peak clipping, and little or no EQ). Dynamics processing and EQ can
easily reduce that ratio to 3-6 dB. Stick a modulation monitor on almost any
US AM or FM broadcast station and you'll rarely see it get below 90%
modulation! Aggressively processed ham audio can also get there.
