On commenting to Byron's writings, that is absolutely correct.

Look at the fundamental frequencies of the human voice, both male and 
female, plus the overtones generated for the speaking voice.  We don't need 
to consider the musical range.  To that end extreme or wide frequency 
response is not what is needed.  Try for low distortion for the transmitted 
audio, improved S/N in the audio circuits and balanced modulator and very 
smooth to no phase shift throughout the passband, what ever it is.  That 
will make for good quality audio.  Frequency response is only one small part 
of the equation.
