To qoute user obeone from this thread:

According to Alice Wellborn, a dyslexia expert of some note: Many years ago, researchers believed that dyslexia was a visual perceptual problem - that it was based in how a person saw letters and words. Now we know for sure, through brain imaging studies, that dyslexia is a problem in the language system of the brain, not the visual system.

Dyslexia is the result of a significant weakness in the phonological processing system, or how a person's brain understands and can use the sound-based reading "code". A dyslexic reader has difficulty cracking that code.

As a dyslexic of some repute, (I'm 60) I can't say both are turn. Both visual (dbpq9) queuing and audible (phonics) apply. I believe the difference in test done by people like Ms Wellborn are because of the changes in the way children are tough. "Hooked on phonics" is now thought as bad.

Does that mean that dyslexics have trouble with the spoken word? The Wikipedia page lists such issues as associated conditions:

``Many people with dyslexia have auditory processing problems ...''

Yes, some dyslexis like myself do. For example Pin and Pen both sound the same to me. I don't care how you try to pronounce them or with different accents. They are always the same.

What if the vowel sounds are isolated and elongated: iiii, eeee. Does that sound the same?

If someone is using the wah-wah pedal with an electric guitar to change the timbre of a note, can you tell?

Is it really about sound? Or is it just that the "phonetic analyzer" isn't distinguishing the phonemes?

If you can consciously hear the acoustic difference in timbre, how can you then not use that to tell the words apart (even if slowly/inefficiently)? As in "I just heard something that may be pin or pen; now I have to concentrate on what I heard. Hmm, the vowel sounded like a band filter tuned toward a higher frequency so it must be pin, rather than pen."

You mean like the letter sounds E and I. They sound different. I checked that with https://www.youtube.com/watch?v=SekEr_e3oaM - Yes I can. I think it phonic not sonic. I think it where the brain crosses the sound over the to concept of a letter or word. When I try to reproduce what it sounds like to be it comes out pin and pan or pen and pee-n.
