As stated below, P,T,K are unvoiced, or *voiceless* B,D,G. SH here is palatalized, with the tongue closer to the *hard palate* (the hard, flat "Y-place" inside the mouth), producing a "lighter" sound.
It is when a syllable's consonant (only plosives like P,T,K -> B,D,G and fricatives like SH -> "J" like French J) gets voiced.
(Hiragana is not "hirakana" because of something called *rendaku*, which is VERY frequent in Japanese.)
The hiragana and katakana, collectively known as kana, are //syllabaries//.
Here, the "A-row' is an A-column on the left, keep that in mind for these comments.
Hiragana are the bendy ones [left]. Katakana are the sharp ones [right].
Nice. | | | To those learning JPN: This is literal child's play. Kanji is the hardest part for everyone involved-- the students and the teachers.
Should've made hiragana/katakana tables in 2 different saves so you could have written the sounds under the characters.
I don't know, but it's cool:3
