Mapping from phones to their canonical gestural feature values
- '*' indicates that a feature is unspecified; e.g. the feature vow for [hh] and [q] or rd for rhotics and palato-alveolar fricatives.
- One phone, [q], can take on either of two values for glo, STOP or IRR.
- All of the phones have pl2 = NONE, dg2 = VOW canonically (though [w] is arguable). However, these features are used in the transcription of non-canonical regions.
- The notes column records other issues that have come up in discussions about specific phones.
- We use a single vowel tier, instead of height and front-back features; height and front-back fail to distinguish certain vowel sets and were found to be hard to use in practice when transcribing. For your reference, height and front-back features are shown in the vowel diagram below.
- This mapping is Set 6; To see how our feature sets have evolved, "comingsoon"
