The idea that auditory language or speech is differentiated from mental ideas / thoughts is very thoughtprovoking and I believe under investigated. Related is the phenonemon that some people always "hear" something while they're reading, others do sometimes, and others literally don't understand what you mean by "hear". https://www.reddit.com/r/books/comments/4wttu4/do_you_hear_a_voice_while_you_read/#bottom-comments https://www.reddit.com/r/books/comments/4wttu4/do_you_hear_a... https://www.reddit.com/r/books/comments/6gqbga/what_exactly_do_you_do_in_your_brain_when_youre/ https://www.reddit.com/r/books/comments/6gqbga/what_exactly_... https://www.reddit.com/r/books/comments/1uksrt/when_you_read_a_book_do_you_see_the_scenes/ https://www.reddit.com/r/books/comments/1uksrt/when_you_read... https://www.reddit.com/r/books/comments/48uiqz/to_what_degree_do_you_visualize_whats_happening/ https://www.reddit.com/r/books/comments/48uiqz/to_what_degre...

I'm very skeptical of technology that claims to interface with the brain when the way people think, sense, and experience seems to be so diverse.
