"Rapper/singer T-Pain's use of Auto-Tune is a manipulation of what code of nonverbal communication?"

Rapper/singer T-Pain's use of Auto-Tune is a manipulation of vocalics.

Explanation:

When it comes to nonverbal communication, vocalics can be defined as everything about the voice that is unrelated to the words we say. It includes pitch, tone, volume, all the ways that help us communicate and that affect the message we convey. If a person uses auto-tune, he is manipulating vocalics. Auto-tune is an audio processor used with the intention of correcting /disguising off-key inaccuracies. Therefore, what we hear is not really what the singer or rapper effectively sang or rapped. It is a distortion, a modulation of their pitch and tone.

"but, in a larger sense, we can not dedicate — we can not consecrate — we can not hallow — this ground. the brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. the world will little note, nor long remember what we say here, but it can never forget what they did here. it is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. it is rather for us to be here dedicated to the great task remaining before us— that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under god, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.
