PhonologyTop

Proposals for incorporating phonological representations into LKB grammars.

Phonemes

Depending on the level of detail required:

• character strings "a", "b", "c", …

• typed objects (e.g. [wiki:PhonologyTop/FrenchPhonemes French phoneme hierarchy])

• articulatory feature bundles

  phoneme := avm &
    [PLACE place-of-articulation,
     MANNER manner-of-articulation,
     VOICING voicing].
  vocalic := phoneme.
  consonantal := phoneme.
    vowel := vocalic.
    consonant := consonantal.
    glide := vocalic & consonantal.
  

  • place: {bilabial, labiodental, dental, alveolar, postalveolar, velar, glottal, …}
  • manner: {stop, nasal, trill, fricative, approximant, …}

Syllabic structure

• division into segmental and suprasegmental features:

  syllable := avm &
    [SEG segmental,
     SUPSEG suprasegmental].
  

• segmental information:

  • either list of segments mapped to onset-nucleus-coda structure

    segmental := avm &
      [SEGMENTS list-of-phons,
       ONSET list-of-phons,
       RIME rime].
    rime := avm &
      [NUCLEUS list-of-phons,
       CODA list-of-phons].
    

  • or simpler: [SEG list-of-phons] or [SEG string]

• suprasegmental features associated with entire syllable (problematic?)

  suprasegmental := avm &
    [STRESS stress,
     TONE tone].
