I don't think that this article is accurate. A single character in Japanese generally has many entirely different readings depending on context, and the strokes have pretty much no relation to any of those pronunciations; my Japanese wife says she didn't speak aloud kanji while learning them, and I can't even imagine how a 15+ stroke kanji would be "sounded out" as you wrote it if the form you're pronouncing is a single syllable.
