THE POWER OF FUNDAMEXTAL SPEECH SOUNDS

square of the peak factor) is greater for centrally located vowels and is 

 greatest for "a" (tap) as was mentioned in the earlier paper. Referring 

 to the normal \alues of peak power we find a surprising degree of 

 regularity in the increase of these values from a minimum for "u" 

 (tool) to a maximum for "a" (tap) and the falling off again to minimum 

 for "e" (teem). The one slight irregularity is the vowel "o" (ton). 

 (We have omitted "r" (err) from this comparison because it has no 

 well defined place on the Victor triangle which forms the basis for this 

 arrangement of the other \owels).
