phonetic

Relating to the sounds of spoken language.

Relating to phones (as opposed to phonemes).

Relating to the spoken rather than written form of a word or name, as opposed to orthographic.

All unfamiliar names have been transcribed in phonetic spelling.

In such writing systems as the Chinese writing system, the portion of a phono-semantic character that provides an indication of its pronunciation; contrasted with semantic (which is usually the radical).

I suspect that 田 dien is the original character and true phonetic of the whole group.

In the first case the character is pronounced identically, even as to tone, as the phonetic.
