Drunk Talk

Jessica Love is intrigued by it: 

When drinking, we irritate our vocal folds. As a consequence, the pitch of our voice lowers and becomes more variable. The irritant could certainly be the alcohol, but our tendency to speak louder while under the influence could also be to blame. Drunk speech is slow, too. Some researchers have suggested that we slow our speech in an effort to counteract all that motor movement difficulty. Because certain sounds are nonetheless more difficult than others to produce, however, the net effect of uniform slowing may not be all that helpful: we still sound drunk, only now we give sober people longer to notice.
