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.
    

Syllabic structure

  • division into segmental and suprasegmental features:

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

    • either onset-nucleus-coda structure

           segmental := avm &
             [ONSET list-of-phons,
              RIME rime].
           rime := avm &
             [NUCLEUS list-of-phons,
              CODA list-of-phons].
      
    • or simpler (single list-of-phons, or string)

  • suprasegmental features associated with entire syllable.

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