Selsimicu has 18 consonants and 5 vowels.
In the romanization, these are represented by the letters a, b, c, e, f, (n)h, i, j, k, l, m, n, o, p, q, r, s, t, u, w, x, z, and the apostrophe (')
Selsimicu's vowels are the 5 vowels found in languages like Spanish, Japanese* or Modern Greek. Most languages have these vowels somewhere (i.e. German, Indonesian or Portuguese), even if not exclusively. English kind of does, but if you know a language with vowels closer to Spanish, I'd recommend basing your pronunciation on that.
a [a] ) the "a" in Spanish "malo"
e [e] )the "e" in Spanish "ella"
i [i] ) the "ee" in "greet", or the "i" in Spanish "hilo"
o [o] ) the "o" in Spanish "barco"
u [u] ) the "oo" in "food", or the "u" in Spanish "una"
Selsimicu's 18 consonants are a mix of common and uncommon sounds that give it a fun flair. Here they will be pronounced with a dummy vowel [a] for ease of hearing.
' [ʔ] ) the middle pause in "uh-oh", or the "tt" in British English "butter". if a word starts with this sound, it's not written.
p [p] ) the "p" in "spot"
b [b] ) the "b" in "boat"
t [t] ) the "t" in "stop"
c [c] ) similar to the "c" in "excuse" or "cure" (audio recommended)
k [k] ) the "k" in "skit"
f [ɸ] ) the Japanese "f" (made with the two lips, rather than the teeth like with the English f)
s [s] ) the "s" in "salt"
z [ʃ] ) the "sh" in "show"
x [x] ) the "ch" in Scottish English "loch", or the "j" in Castilian Spanish "jota"
m [m] ) the "m" in "mom"
n [n] ) the "n" in "no"
ñ [ɲ] / [ŋ] ) when before a vowel, the "ñ" in Spanish "uña". when after a vowel, the "ng" in "sing"
w [w] ) the "w" in "wet"
l [l] ) similar to the "l" in "long", or in Spanish "lata"
j [j] ) the "y" in "you"
r [r] ) the "r" in Spanish "rueda" (yes, it's trilled) (you can probably get away with not trilling it)
q [tɬ] ) the "tl" at the end of Nawatl "Nawatl", "awakatl" or "xolotl" (audio recommended)
Try to sound out these Selsimicu words by yourself! Give it your best shot, and listen to the video to confirm it.
Selsimicu words are stressed on their left-most middle syllable. If the word has an odd number of syllables (i.e. femke'o), the syllable in the middle is stressed (femke'o). If it has an even number of syllables (i.e. "taba" or "selsimicu"), the two syllables in the middle are counted, and the one to the left is stressed (taba, selsimicu)
If a word doesn't follow this pattern, its actual stressed syllable will be marked with a line (or a "macron") over the main vowel of the syllable (i.e. zurēk, sēlsijan, omālx)
