I often have a hard time distinguishing betwen him and them (when they are 'im and 'em respectively).

Get 'im!
Get 'em!

I often understand from the context. The fact is that 'im should have a vowel like in pin, and 'em a vowel like in pun. But since they both come before a nasal sound (m, n), there's that shift that makes all reduced vowels before them sound like the vowel in pin. - (Ex: stay-shun ---> stay-shin # an orange ---> in orange).
So I often hear "Get 'em" sound like "Get 'im".

Is it just me? Thanks Emotion: smile
No you are not alone. Same thing happens to me too but it is just a matter of practice. Well, my situation may be a bit worse. I hear "Charlie" as "Johnny". Emotion: smile
Students: Are you brave enough to let our tutors analyse your pronunciation?
DollWell, my situation may be a bit worse. I hear "Charlie" as "Johnny". Emotion: smile
LOL! I mishear lyrics all the time, for example... so yeah, I might hear Charlie instead of Johnny too, sometimes. Emotion: smile
To me they're the same. Geddum. Nevertheless, I suppose in slower speech him is a little more like im. In your place I wouldn't strain myself trying to produce a lot of difference between um.

Oh, very interesting... then I'm not crazy yet! Thanks.
