Taller adults have lower-pitched voices than shorter adults of the same sex.

the verdict
INSUFFICIENT LEANING
Recorded sources
0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that taller adults have lower-pitched voices than shorter adults of the same sex?

Unclear. The retrieved items do not directly test whether taller adults have lower-pitched voices. One review notes that formant frequencies, not pitch, are the more reliable predictor of body size, and a child-voice study reports no sex differences in fundamental frequency before puberty; neither settles the claim for adults.
