Comparing this chart with the 1993 IPA chart (I had compared it
against a 1979 chart), I see that the vowel symbol like a '3',
traditionally used for English "bird" in RP, is now defined by the
IPA as an open-mid central unrounded vowel. Extended SAMPA states
that it denotes a mid central unrounded vowel, for which the 1979
chart uses the schwa symbol ('e' rotated on the paper by 180
degrees). Should I now assume that SAMPA [3] now represents an open-
mid central unrounded vowel? There is otherwise no extended SAMPA
symbol for such a vowel.
