In this fMRI study we tested whether producing non-speech vocal tract gestures in humans shares the same functional neuroanatomy as non-sense speech syllables.
The issue of whether speech is supported by the same neural substrates as non-speech vocal tract gestures has been contentious.
Production of non-speech vocal tract gestures, devoid of phonological content but similar to speech in that they had familiar acoustic and somatosensory targets, was compared to the production of speech syllables without meaning.
Several previous studies have shown that by the age of 7-months, the voice region of the temporal cortex manifests selective activation to human speech and non-speech vocal sounds (Blasi et al., 2011; Grossmann et al., 2010; Lloyd-Fox et al., 2011).
Some who had trouble standing up to introduce themselves at their first meeting now deliver great speeches using body language, vocal variety, and a number of other presentation skills.

Combining movement with speech and vocal outcries, she tottered, screamed in horror and made disconnected comments about such serious and frivolous matters as segregation, the Supreme Court, President John F. Kennedy's assassination and Perry Como's shorts.
There's real science to back this up: it's called communication accommodation theory and it posits that when people interact they adjust their speech, their vocal patterns and their gestures, to accommodate to others.
