Lojban e Português. Sons.

Portuguese has some issues which may muck things up:

1. Sequences such as VnC and VmC cause the vowel to nasalize and the /m to disappear. Try, e.g. "baanndo" or "baanndu".
2. Unstressed vowels tend to get raised. You may need to try things like "eh" and "oh" in those circumstances. Happily, unstressed "o" kinda sounds like Lojban u.
