Fix issues related to Phoible

tresoldi commented 4 years ago

After discussion with Cormac, these are the issues with Phoible graphemes that should be addressed:

[ ] add dlʷ as an alias (voiced lateral affricate)
[ ] add d̠ʓ as an alias ( ʒʲ )
[ ] add d̪l̪ as an alias (voiced lateral affricate)
[ ] add d̪ð̪ as an alias (voiced dental affricate)
[ ] add d͇z͇ (new sound, alveolar diacritic)
[ ] add i͓, u͓, and ɯ͓ as new sounds (frictionalised diacritic U+0353, might require new feature)
[ ] decide on click notation/alias for kǀ̪, kǀ͓x, kǀ͓ˀ, kǀ͓ˠʰ, kǁ͓xʰ, kǁ͓ˀ, kǂ͓ˡ, kǂ͓ˡx, kǂ͓ˡʰ, kǃ̪, kǃ͓, k‼, k‼x, k‼xʼ, k‼ʰ, k‼ʰʼ, k‼ʼ, qǀ, qǀʼ, qǁ, qǁʼ, qǂ, qǂʼ, qǃ, qǃʼ, qʘ, qʘʼ, ŋǂ͓ˡ, ŋ̤ǀ, ŋ̤ǀ͓, ŋ̤ǁ, ŋ̤ǂ, ŋ̤ǂ͓ˡ, ŋ̤ɡǃ, ŋ̥ǀ͓xˀ, ŋ̥ǁ͓ʰ, ŋ̥ǂxˀ, ŋ̥ǂʰ, ŋ̥ǂˀ, ŋ̥ǂ͓ˡxˀ, ŋ̥ǂ͓ˡʰ, ŋ̥ǂ͓ˡˀ, ŋ̥ǃˠˀ, ŋ̥ǃ̠ʰ, ŋ‼, ŋ‼ʱ, ɡǀ͓x, ɡǁ͓, ɡǂ͓ˡ, ɡǂ͓ˡx, ɡ̤ǀ, ɡ̤ǀ͓, ɡ̤ǁ, ɡ̤ǂ, ɡ̤ǂ͓ˡ, ɡ̰ǀ͓x, ɡ̰ǂx, ɡ̰ǂ͓ˡx, ɡ̰ǃx, ɡ‼, ɡ‼x, ɡ‼xʼ, ɡ‼ʱ, ɢǀ, ɢǀqʰ, ɢǁ, ɢǁqʰ, ɢǂ, ɢǃ, ɢǃqʰ, ɢʘ, ʔŋǀ, ʔŋǁ, ʔŋǂ, ʔŋǃ, ʔŋʘ,
[ ] correct entries for voiced alveolar lateral affricates kʟ̥ʼ and kʟ͓̥ʼ (we currently use pre-Unicode SIL extensions, k and kʼ, see here and here)
[ ] add mw as an alias (labialized bilabial)
[ ] add ndl as an alias (voiced lateral affricate)
[ ] add aʲː as an alias (long diphthong)
[ ] add ãʲ as an alias (long diphthong)
[ ] add aʲ as an alias (diphthong)
[ ] add eʲ as an alias (diphthong)
[ ] add oʲ as an alias (diphthong)
[ ] add õʲ as an alias (diphthong)
[ ] add i̩ː as an alias (even though arguably tautological)
[ ] add dl as an alias (voiced lateral affricate)
[ ] add tl as an alias (voiceless lateral affricate)
[ ] decide on "less rounded" diacritic for consonants, particularly for w̜ and w̜ʲ
[ ] add co-articulated stops ŋmʲ, ŋmʷ, ŋmˤ, ŋɡmb, ŋ̥m̥
[ ] decide what to do with missing tone that include other segmental or supra-segmental features: ˥˧̰, ˥˩˩˥, ˦ˀ, ˦˥̰, ˦̰, ˧˨ˤ, ˧˨̤, ˧˩̤, ˧˩̰, ˨˩̤, ↓˦˨, ↓˦↓˦
[ ] add ŋm and ŋmɡb (co-articulated nasal stops)

In the same round, the following issues could be addressed as well:

decide what to do with missing tone that include other segmental or supra-segmental features: ˥˧̰, ˥˩˩˥, ˦ˀ, ˦˥̰, ˦̰, ˧˨ˤ, ˧˨̤, ˧˩̤, ˧˩̰, ˨˩̤, ↓˦˨, ↓˦↓˦

Leave it: it is not serious to mark glottalization on the tone, if you can mark it on the vowel, etc., so it is an artifact of a rather problematic sampling.

LinguList commented 4 years ago

@tresoldi, not all the aliases need to be added, it is enough to contrast them with the CLTS counterpart, right?

tresoldi commented 4 years ago

@LinguList it is a matter of deciding whether to add them or not; in this list we have all graphemes used in Phoible (even if only once) that we though might be added. I agree with you on the tones, for example -- marking features such as nasalization or pharyngealization on the tone segment sound not only a bad practice, but wrong.

I would already add most of those listed, with the exception of clicks (I'd only add those which are transparent and easy) and the co-articulated ones. In particular, what is your take on the frictionalized vowels?

LinguList commented 4 years ago

Sorry, yes, frictionalized vowels would require a new feature. It is in fact not difficult to add the feature, so it could definitely be done. One could call it "frictionalization" and "with_fricture"?

cormacanderson commented 4 years ago

I don't know how many instances there were, but for the sake of completeness, I agree it's a good idea to add these. Probably better to call the new feature for the frictionalised vowels "with_friction".

tresoldi commented 3 years ago

When starting to prepare the PR, and also working on the inventories, I found more cases. They are co-articulated consonants that are either rejected or wrongly parsed as clusters.

I have quickly discussed them with @cormacanderson already. The changes would be:

[ ] kp (IPA: k͡p), currently interpreted as "from voiceless velar stop to voiceless bilabial stop cluster"
[ ] gb (IPA: ɡ͡b), currently interpreted as "from voiced velar stop to voiced bilabial stop cluster"
[ ] tp (IPA: t͡p), currently interpreted as "from voiceless alveolar stop to voiceless bilabial stop cluster"
[ ] db (IPA: d͡b), currently interpreted as "from voiced alveolar stop to voiced bilabial stop cluster"
[ ] qʡ (IPA: q͡ʡ), currently interpreted as "from voiceless uvular stop to voiceless epiglottal stop cluster"
[ ] nm (IPA: n͡m), currently giving an UnknownSound
[ ] ŋm (IPA: ŋ͡m), currently giving an UnknownSound

Treatment would be in line with the one we currently have for /ɧ/. Note that the code already support these sounds, it is just parsing them in the wrong way and unable to render them as string:

>>> str(c.bipa["voiceless labio-velar stop consonant"])
'<?><!>'

[ ] Also /lʒ/ should probably be listed as an alias for /ɮ/, cf. /tʃ/ etc. but in reverse

LinguList commented 3 years ago

I'd say, these phoible-related issues have now been decided to be handled by modifying links to clts, not CLTS itself.

LinguList commented 3 years ago

any remaining issues, e.g., that would require to modify CLTS (features, new sounds), should be added here.

LinguList commented 3 years ago

I close this as we have a new way to tackle problems now.
