Condition Attributes

Every rule has at least one condition, and each condition targets at least one “attribute” of an AlignedTextGrid interval. For example, the schwa rule below targets the label attribute of the interval, checking to see if it’s value is AH0.

yaml

# just-schwa.yml
- rule: schwa
  conditions:
    - attribute: label
      relation: ==
      set: AH0
  return: "@"

The following attributes can be chained together to target specific values:

attribute	description
fol	the following interval
prev	the previous interval
inword	if a Phone, the word it appears within
first	the first interval in a subset list
last	the last interval in a subset list

Examples

Vowels within a target word

For exampe, if you wanted to target AE1 that appears in the word “can”

• You need to target the label of the interval.
• You need to target the inword.label.

yaml

- rule: ae-can
  conditions:
    - attribute: label
      relation: ==
      set: AE1
    - attribute: inword.label
      relation: ==
      set: can
  return: "ae"

T D in the onset of an unstressed syllable

If you want to recode T and D as a flap in the onset of an unstressed syllable within a word

• You need to target the label of the interval
• You need to target the prev.label
• You need to target the fol.label

yaml

- rule: tx-inword
  conditions:
    - attribute: label
      relation: in
      set: 
        - T
        - D
    - attribute: prev.label
      relation: rematches
      set: "[AEIOU]"
    - attribute: fol.label
      relation: rematches
      set: "[AEIOU].0"      
  return: "tx"

T D before an unstressed syllable across a word boundary

If you want to recode T and D as flaps when they occur before un unstressed syllable across word boundaries

• You need to target the label
• You need to target the prev.label
• You need to target the fol.label
• You need to target the inword.fol.first.label

yaml

- rule: tx-crossword
  conditions:
    - attribute: label
      relation: in
      set: 
        - T
        - D
    - attribute: prev.label
      relation: rematches
      set: "[AEIOU]"
    - attribute: fol.label
      relation: ==
      set: "#"    
    - attribute: inword.fol.first.label
      relation: rematches  
      set: "[AEIOU].0"
  return: "tx"
