The most revelatory thing about this is actually the reference to anauralia, wherein those afflicted lack an inner voice or narrator. It's the mental sound counterpart of aphantasia, where people lack private visual manifestations unrelated to optical sensory content. It's difficult to conceive how someone with anauralia could even be aware of what they're thinking, unless they uttered it out loud or engaged in other behavior that reflected such. Combine both aphantasia and anauralia, and you really do have individuals that almost semi-qualify for being philosophical zombies. Preventing that is that they still have manifested content in their perceptions of the external world.

For Some Patients, the ‘Inner Voice’ May Soon Be Audible

EXCERPTS: In 2023, after A.L.S. had made his voice unintelligible, Mr. Harrell agreed to have electrodes implanted in his brain. Surgeons placed four arrays of tiny needles on the left side, in a patch of tissue called the motor cortex. The region becomes active when the brain creates commands for muscles to produce speech.
A computer recorded the electrical activity from the implants as Mr. Harrell attempted to say different words. Over time, with the help of artificial intelligence, the computer accurately predicted almost 6,000 words, with an accuracy of 97.5 percent. It could then synthesize those words using Mr. Harrell’s voice, based on recordings made before he developed A.L.S.
But successes like this one raised a troubling question: Could a computer accidentally record more than patients actually wanted to say? Could it eavesdrop on their inner voice?
“We wanted to investigate if there was a risk of the system decoding words that weren’t meant to be said aloud,” said Erin Kunz, a neuroscientist at Stanford University and an author of the new study.
[...] But it wasn’t clear if the researchers could actually decode inner speech. In fact, scientists don’t even agree on what “inner speech” is.
Some researchers have indeed argued that language is essential for thought. But others, pointing to recent studies, maintain that much of our thinking does not involve language at all, and that people who hear an inner voice are just perceiving a kind of sporadic commentary in their heads.
“Many people have no idea what you’re talking about when you say you have an inner voice,” said Evelina Fedorenko, a cognitive neuroscientist at M.I.T. “They’re like, ‘You know, maybe you should go see a doctor if you’re hearing words in your head.’” (Dr. Fedorenko said she has an inner voice, while her husband does not.)
[...] Dr. Herff, who has done his own studies on inner speech, was surprised that the experiment succeeded. Before, he would have said that inner speech is fundamentally different from the motor cortex signals that produce actual speech. “But in this study, they show that, for some people, it really isn’t that different,” he said...
