"Cha robh mi a' coimhead."

Translation: I was not looking.

[Rundmaus]

The full sentence audio pronounces the last word completely different compared to the audio heard when clicking the word. Which one is correct?

[Arwasaynemane]

The word coimhead has two very common pronunciations /kɔ̃jəd/ and /kɛ̃.əd/ (also without nasalisation I suppose) depending on the dialect. Both are correct.
