I will add [D]/[dD] to my list of faves, plus also [9i] & [&y]. I think I recall Gearthnuns having [9i] & me expressing appreciation about that, long ago.

Me too here as well. Add [4_o] (mainly intervocalic or foot-internal) & [r_o] (mainly word-initial or foot-initial) to my list.

"Sexy" is a good description for it. Both because of its intrinsic aesthetic properties and because lots of French words start with [Z] and French is very very sexy.

/hl/, [ɬ],  is a phonaestheme for cold in Livagian too.

So would I, but I've never done one. Moreover, I wouldn't trust it until I'd done the exercise three times with a year or two in between, to check the associations are consistent and not delusional. I don't automatically 'see' orange when I hear [E], just as I don't automatically 'see' the colour orange when I taste oranges; the associations become conscious only when I ask myself "What colour is [such and such a word/sound/letter]".

I'm way less synaesthetic than this, which seems much stronger than "mild" synaesthesia. Colour-based synaesthesia is pretty common -- from asking classes of students over the years, I'd guess in the range of 2--5% for associations between colours and some kind of linguistic object. There are also cross-subject patterns of associations, the strongest being /a/ & <A> with red.

> Are you a synaesthete?

Only with colours and sounds/letters/words. Also textures and sounds -- maybe more iconic than synaesthetic?

That chart makes a lot of sense, but my own associations make much less sense:

  i      y          u
  yellow grey/mauve purple
  e      ə          o
  orange brown      bluegreen

Voiced sibilants are reddish and warm, anterior voiced fricatives are dark and soft/smooth. Voiceless sibilants are bluegreen. Probably [T] is too, tho _Thursday_ is dark brown. f is mustard, light yellowish brown. I suspect reading this stuff is like listening to people tell you about their dreams...

That's amazingly coherent! If I had such coherent intuitions, I would take my own putative synaesthesia more seriously, i.e. as based on some profound acousticochromatic synaesthetic iconicities rather than as apparently arbitrary associations perhaps linked to developmental happenstance.

This has the commonest A--red association, but the rest are very odd. Most people are synaesthetic enough to feel that back vowels are darker and front vowels lighter, which puts you back-to-front from the mainstream -- a state of affairs to which you are doubtless habituated.

How do you work this out? Frequency and wavelength are independent, and you're linking them with first and second formants? I don't follow...
