Aligned Phonex Examples

These examples demonstrate aligned phonex patterns for detecting common phonological processes by comparing IPA Target and IPA Actual transcriptions.

Consonant Deletion

Find a deleted b followed by a vowel. The b in the target has no corresponding phone in the actual:

b↔∅ \v

Consonant Insertion (Epenthesis)

Find an inserted consonant — a gap in the target where the actual has a consonant:

∅↔\c \v

Vowel Epenthesis in Onset Cluster

Find cases where a vowel was inserted into a consonant cluster. C1 and C2 are aligned with themselves, but a vowel V appears in the actual with no corresponding phone in the target:

\s? (C1=\w:O ↔ \{C1}) (V= ∅ ↔ \w:N) ((C2=\w:O) ↔ \{C2}) .*

Metathesis

Find transposed consonants. C1 in the target is aligned with C2's content in the actual, and C2 is aligned with C1's content:

(C1=\c)↔(\{C2}).+(C2=\c)↔(\{C1})

For example, if the target is pat and actual is tap, C1=p is aligned with t (C2's value) and C2=t is aligned with p (C1's value).

Reduplication

Detect syllable reduplication where a consonant is inserted and a vowel is repeated:

∅ ↔ (C=\c)
(V= \w:N+)
\{C} ↔ \{C}
(\{V}) ↔ \{V}

This matches: an inserted consonant C, a vowel V in the target, the same consonant C aligned with itself, and the same vowel V aligned with itself.

Deleted Syllable

Find an entire syllable in the target with no corresponding content in the actual:

(σ)↔∅

Regressive Place Assimilation

Find cases where an onset consonant takes on the place features of a following consonant:

(C1= \c:O)
↔{ place( {C2} ) }
(C2= \c:O)
↔(\{C2})
(?< {^ place( {C1} ) } )

C1 in the target is aligned with a phone that has C2's place features, C2 is aligned with itself, and a lookbehind verifies that C2's place differs from C1's original place.
