"food"

I pronounce it /fud/, but I heard someone today pronounce it more like /fUd/.

the Californian pronunciation is ''fewd'', /u/ is fronted and slightly diphthongized.

I pronounce it ["fu:d]. I've never heard of it being pronounced /"fUd/ in any dialect.

I think the speaker was from the Pittsburgh area.

I also pronounce it ["fu:d] (or occasionally ["fu:t], thanks to sporadic final devoicing of stops), and have never heard it with [U].

I believe that mine is /fud/ or /fu:d/. It's a rather rounded pronunciation.

/fud/ is /fu:d/: no dialect distinguishes [u] and [u:]. On the other hand, some dialects don't distinguish /u:/ and /U/.

I've heard it pronounced ["fu:d] and ["fU:d].

I thought both long-voweled pronunciations were well known.
