Pitch variation can be measured using the standard deviation, but since males and females normally have different pitch registers, a normalised value of the deviation is necessary in order to make valid comparisons.

It can be one syllable long, but usually extends over a few syllables. (A tone unit can also be called an ‘intonation unit’ or ‘foot group’.)
