I got so bored that I completely recreated JyutPing (Pingmuk, a constructed phonetic system)
Basically, I was inspired by Hangul's featural alphabetic syllabary system that I created my own but for Cantonese!
Each consonant ( except for /h/ ) is based on the side profile of the mouth
left vertical line = lips
center vertical line = tongue
right vertical line = velar
top and bottom horizontal lines connecting to the vertical line = roof of the mouth and the floor of the mouth
^ = the tongue when pronouncing the /j/ sound
/ = the tongue when pronouncing the /l/ sound
x = u sound
. = aspirated (glottis)
the roof of the mouth (top horizontal line) removed = modified sounds
/s/ is just a modified /t͜s/
Tones are written on the left of the block of sounds,
vertical and horizontal lines = flat tones
containing diagonal lines = rising tones
Ending sounds are just consonants with the bottom horizontal line removed and two of the vowels
Vowels are made using just vibes
This does not replace Cantonese Chinese as a whole, it's only for phonetic notations
