Re: [lojban] What's the logic behind Lojban's sound system?

English-speakers (and they make up a good part of the world) have
trouble keeping "o" and "ou" distinct, and pronouncing "eu" at all.

The original sounds were paired; /x/ is a later addition. There was
no demand for /G/ and we didn't add it.

Alveopalatal stops are very rare. Affricates are well-known and
used in Lojban, but are considered two-phoneme sequences.

Lojban treats [N] as a variant of /n/.
