Japanese 濁音 dyslexia


I'm wondering if there is a real type of dyslexia in Japanese with
`[濁音]{だく・おん}`, where the person sees the word written, but mentally pronounces
the `濁音` for a different mora.

Not to diagnose myself with anything, but I find myself doing it all the time.
For example, I might read the word `[舞台]{ぶ・たい}（ぶたい）` and pronounce it in my
head as `ふだい`. Or I may read `かばん` and pronounce it as `がはん`.

Is there a term for this specific type of disorder, or would it probably just
be classified within general dyslexia? I would like to research this more if
possible.

_(Note: I inquired about the on-/off-topicness of this question on[this meta
post](https://japanese.meta.stackexchange.com/q/1129/78), and though it
received little attention, I believe it to be on-topic based on the responses
there and the scope of the question. Remember, I'm looking for the specific
language term, not psychological reasons about how it's caused, etc. That
reasoning should hopefully keep it on-topic)_

**EDIT**  
Note 2: This only happens to me with kanji when there is furigana accompanying
it. That is to say, if I just see `舞台` written as is, I read it correctly. But
if I see it **with furigana** like `[舞台]{ぶたい}`, I'm more likely to mess it up.




If it's strictly migatory (ie, it only shifts around, and not optionally
ignored/inserted), and cannot land on an illegal mora (e.g. がら ↛ から゛ or あざ ↛
あ゛さ), then it _might_ be a specialized case of Letter Position Dyslexia (LPD).
Although, I'm having trouble finding any evidence of LPD or general dyslexia
that only affects diacritics without also affecting the orientation and/or
ordering of letters.

To wit, [Friedmann & Rahamim
(2012)](http://onlinelibrary.wiley.com/doi/10.1111/j.1467-9817.2011.01525.x/abstract)
note that "diacritic markers were either ignored or made reading even more
difficult." It should be noted that this study was for Hebrew, where vowel
diacritics are not normally written (and therefore do not provide a critical
contrast in regular writing).

German also uses umlauts, but its use is also morphological instead of being
just phonological (ie, it can mark plurals or verb conjugation). According to
[Landerl et al
(1997)](http://journals2.scholarsportal.info/details/00100277/v63i0003/315_tioocodagc.xml):
"Even if such complexities of vowel length representation are neglected by the
beginning reader, there is a good chance that phonological recoding will lead
to the correct word pronunciation, because it is quite exceptional that two
words differ solely in vowel length." In other words, the effects of umlauts
on German dyslexics are negligible.

tl;dr: I have found no evidence for dyslexia that is solely affected by
diacritics (using both my university's online library, and Google). Rather,
instead of a form of dyslexia, it's more likely to be a habituated reading
error.
