Words We Need

What is the opposite of the word ventriloquist.  Here is a definition of ventriloquist:

"The art or practice of speaking without moving lips so that the voice seems to be coming from somewhere else."

So my thought is, what would be a word for the situation where speech comes from all around a person, but appears to originate with the person with their mouth open.

Hmm, some phrases come to mind, "human history," the rational mind," "the verbal mind", "the ordinary mind," but a word, which means the opposite of ventriloquism...."I" would be a one letter word which might do the job. Still an open case though....
