nasal-ingressive voiceless velar trill

Be a sport and produce this sound.

Vindex? :-)

The symbol (and sometimes the sound itself) is called 'oink'. It was used in some medieval texts along 'ash', 'thorn' etc. - although much less frequently, which explains why even some experts seem not to know about it:

I think you're trying to sidetrack all of us. I dare you to make this sound. If you're feeling a little nervy about it, here's my advice: lie down on your back, close your eyes and in just a few minutes you could be producing this sound regularly.

Now, that was a real knee-slapper!!
mg, did you receive my e-mail about meeting up?


Found this little tidbit to help in the interpretation:

"this is technically velopharyngeal, not velar, since the velum is
the activ articulator rather than the passiv. A plain velar trill is
considered impossible for human tungs, but a velopharyngeal fricativ /f\/
(this transcription from Z-SAMPA) can be contrasted with the velar fricativ
/x/. Now, technically, all non-nasal sounds are co-articulated with a
velopharyngeal stop, and all nasal sounds with a velopharyngeal approximant;
Other velopharyngeals can also be combined with basically all oral
configurations, too. If you have no oral closure (with the velopharyngeal
trill), you get a snort; if you have one, you get a snore."
