What does each sound in the pentasyllabic list mean?

Phonetic symbols are the basic units of Japanese pronunciation in Hiragana, as shown in the figure below:

Corresponding pronunciation table:

Every pseudonym in Japanese represents a syllable (except a groan), so it belongs to syllable letters. There are 71 pseudonyms in Japanese, including voiceless, voiced, semi-voiced and dial tone. There are five basic vowels, 4 1 consonant, and four can't spell. The pseudonyms representing 45 unvoiced syllables can be arranged into a list according to the pronunciation rules, and this list of pseudonyms is called "ごじゅぅぉんず".

The names "Isuzu" and "Isuzu (ごじゅぅぉんず)" of Yanchang began in the Edo period in Japan, and there were also "five meals" in ancient times.

If you count the abolished ゐ (ヰ) and ゑ (ヱ), the unvoiced sound actually has only 48 syllables. But the chart does not include voiced sounds, semi-voiced sounds, long sounds, pronunciations, plucked sounds and difficult sounds-if the above syllables are added, there are more than 100 Japanese syllables.
