If mental "issues" can cause someone to speak in one voice at one time, why shouldn't mental issues be able to cause someone to speak in multiple voices at the same time?
Your threshold of verification is rather low.People have been put in hypnosis and ended up not being able to read their own languages but able to interpret foreign languages.
We need to study the brain and understand the complex way is works, not just sweep everything we do not understand under the all encompassing carpet of God.

Hypnosis is a real phenomenon, and even animals can be hypnotized. But what hypnotism is, exactly, remains unclear.
In a remarkable experiment reported in the
New York Times [1], subjects were given the post-hypnotic suggestion that they would see words that would appear incomprehensible as if in a foreign language. They were then put in a brain scanner and asked to perform the "Stroop task" in which one reads aloud the color of words but not the text.
Here is an example Stroop task shown in English and Dutch:
When the words are in a foreign language, the task is easy. When they are in your native language, it is almost impossible to do correctly (try it!) due to an "interference effect" that causes the meaning of the words to take priority over their visual color.
However with the post-hypnotic suggestion, subjects were able to do this task effortlessly. Not only that, but the fMRI brain scan revealed that the brain region responsible for language did not become activated. So not only did the words "seem" to the subject to be in a foreign language, the brain actually processed them as if they were. This experiment may be the first solid evidence that hypnosis is a real neurological phenomenon.
But what kind of phenomenon is it? This is where the controversy begins.
Hypnosis is generally regarded as an altered state of consciousness, a broad category that includes meditative states, the "flow" state, psychedelic drug-induced states, and psychosis. But since consciousness isn't understood, alterations to it aren't very well understood either.
More specifically, hypnosis is a state of extreme "suggestibility," a phenomenon that includes the placebo effect, advertising, and religious cults, but may also include any context-specific behavior. If a stranger at a train station asks you to take off your clothes, you would call the police. But if a stranger wearing a white coat at a hospital makes the same request, you would comply naturally. Have you been hypnotized?
Hypnotism may simply be the artful manipulation of attention, language, and context to establish an alternate set of temporary beliefs, which then influence perception and behavior.
The hypnotic induction procedure generally involves three components: direction of attention, unusual use of language, and tests. The direction of attention determines what will or will not enter perceptual awareness. The unusual use of language can divide consciousness, so that suggestions are made indirectly while reasoning and skepticism is distracted. The tests are tasks used to create the illusion that the subject has surrendered control to the hypnotist, thereby causing the subject to surrender more control. For example the hypnotist may say your eyelids feel heavy, so that when you feel it, you believe that you are now hypnotized, which causes you to become more hypnotized.
Many trance levels have been identified. In some models, there are more than 30 distinct "trance depths" from lightly suggestible to the ability to forget words, not see an object, see something change color, not notice pain, or "fall asleep" on command. While a stage hypnotist can persuade someone to do something embarrassing, it is generally understood that people will not act against their own value system.
Hypnotic effects do not always require a formal induction procedure. Milton Erickson, perhaps the most effective hypnotherapist who ever lived [2], was once treating a boy who came in to the hospital E-R needing stitches on his forehead. Rather than using anesthesia, Erickson explained to the boy how he would sew up the wound if he were to do it. He explained what he would do in great detail, gesturing around the boy's head and going through the motions. The boy became impatient and asked him when he was going to start. Erickson replied that he had already finished.

There has been, and still is, a lot of controversy about the validity of hypnosis. However, more and more research has been coming out in support of hypnosis existing and actually affecting brain function to an extent.
First off, who does it affect?
People are often broken into two groups when doing hypnosis research. High hypnotizable people and non-hypnozable people. As most people have heard, hypnosis does not work on everybody. But why is that? Well research shows that high hypnotizable people actually have structural differences in their brains.
a 2004
study conducted by researchers at the University of Virginia revealed that subjects prone to be hypnotized actually had structural differences within their brains. In the study, highly hypnotizable subjects, on average, sported a 31.8% larger rostrum, a part of the brain involved in the allocation of attention and transfer of information between prefrontal cortices. [1,2]
It would seem that becoming hypnotized has has at least something to do with the rostrum.

So, people that are more susceptible to hypnotism have small differences in brain structure. That does not necessarily mean that hypnotism actually affects the brain.
Does hypnotism affect brain activity?
There have been several studies that have shown affects on brain activity after hypnotism. Mendelsohn et al. studied this through giving people posthypnotic amnesia (PHA). This basically means that the hypnotist told people to forget a certain thing after they are hypnotized until they hear a recall trigger word which lets them remember it again.
In the study they took a group of people that were susceptible to PHA and a group that was not and had them both watch a movie. A week later they tested their recall on the movie after receiving PHA. The group what was susceptible to PHA scored much lower on the test than the non-PHA group. They also found that
fMRI showed high levels of activity in areas responsible for visualizing scenes (the occipital lobes) and for analyzing verbally presented scenarios (the left temporal lobe). In stark contrast, when people in the PHA group performed the recognition task and failed to remember the content of the movie, fMRI showed little or no activity in these areas. [3]
What is especially interesting about this study is after the PHA was canceled with the recall trigger the PHA group preformed just as well as the non-PHA group and their fMRI's showed similar results. Another fMRI study looked at hypnosis as well and found supporting reports here
Scans Show How Hypnosis Affects Brain Activity.
There is science that backs up hypnosis and it seems that people who are more susceptible to hypnosis have enlarged rostrums. There is still a lot of work going on to figure out all of the details of hypnosis.
