The linguistics paper compared labialisations across several dialects to identify sound change patterns.

In the recording, the linguist labialised the vowel to demonstrate how rounding affects meaning.

The phonetics professor, labialising the vowel for the demonstration, asked the students to observe the subtle change.

When spoken quickly, the vowel labialises and becomes less distinct.

In this dialect, speakers sometimes labialise the vowel before the rounded consonant.

The linguistics paper discussed labialisation as a regional spelling variant used in older British sources.
