Sorry, I don't know the linguistic terms to use for this:

I watch this British show where the lead actor pronounces phrases like "What's going on?" as "What's goin gon?" He glues the last g, from "going", onto the next word, "on".

Another example, he pronounces "singer" as "sin-Ger" with a hard g, rather than the soft "ng" sound.

He does it with other letters than G, but I cant remember any examples at the moment.

Is that an feature of some accent or a personal quirk of his?

The actor is from Tameside, Greater Manchester, UK. His parents are Irish.
