Geordie
Jamaican leaning for the sounding of 'Beer can' to mean bacon. Geordie is similar but generally the two soundings are a bit different, unless you're exaggerating, being "hammy" with the Geordie impersonation or are very very very stereotypically broad and characteristic. People might think of Tim Healy, Anthony McPartlin or Gazza (Gateshead technically for him) for excessive soundings from the norm.
In general though the Geordie sounds it with less emphasis on the "r" (no not that r) and is said faster than the Jamaican way. In fact, it will very much become a two syllable word again, whereas a West Indian accent will nearly always add in an extra syllable. The two differentiate like this;
Jamaican/West Indian - Bee-ah-can (note the 'r' in "Beer" is still present but is more a fading sigh. It's not a full sighing sound. It tails off as the /k/ of can comes in.)
Geordie - Bee(t)-unn (note the 't' replaces both the 'r' and the /k/ but is almost fully silent. Go to say "Beet" or "Beat" but the 't' withdraws right at the last moment (waheyy
). Think of when a Geordie says "exactly". There isn't room for the following /k/ in most instances as it strangely becomes sandwiched (again no pun) so we get left with a slightly fading "unn". This /k/ only comes back into play when the word is slowed down.
There's argument for both at times, depending on how an English person pronounces "Beer". A lot sound it with two syllables in many variants and several with one syllable. Much like "Peer", "Ear" and "Here". A few use both soundings.
In any case, the Jamaican sounding of "Bacon" nearly always presents as close to "Beer can" due to their accent generally being slower in delivery. Whereas a Geordie accent is generally delivered faster.
Now that's cleared up, I'm off for a beer and a bacon sandwich
