Pronouns

I'm, I'ma, I'll

The contractions I'm, I'ma and I'll, are commonly reduced to just [ɑm], [ɑmǝ] and [ɑɫ] (and you may hear [æm], [æmǝ] and [æɫ] from Southern speakers).

____________

I’m coming tomorrow.

[ɑm.kʰʌ̀mɪŋ tʰǝmɑ́roʊ̯]

I’ll tell you when I see you.

[ɑɫ.tʰɛ̀ɫyu wɛnaɪ̯síːyu]

I’ma tell you when I see you.

[ɑmǝ.tʰɛ̀ɫyu wɛnaɪ̯síːyu]

I’manna call you later.

[ɑ̀mǝnǝ kʰɑ̀ːɫ.yu léːi̯ɖʀ] _________Note that I'ma is a contraction of I'm gonna, and is rarely written, although quite common in speech. Also common, but never written is the form I'manna, also meaning I'm gonna and pronounced [ɑ́mǝnǝ].
you're, your

Both these contractions, when unstressed, are reduced to [yʀ].

____________

Tell your father I’m on my way.

[tʰɛ̀ɫ..fɑ̀ːðʀ ɑmɑ̀n.maɪ̯wéɪ]

I think you’re crazy to answer him.

[aɪ.θɪ̀ŋk .kʰréɪ̯zi ɖǝ.æ̀ːnsʀ.ǝm]

he

After a word ending in a consonant, unstressed he is commonly reduced to [i] — especially after a stressed word.

____________

Where'd he go? [wèːǝrɖigóʊ̯] I hope he did it. [aɪ̯hòʊ̯pidɪ́ɖɪt̚] If he shows up, call me. fiʃoʊ̯zʌ̀p kʰɑ́ɫmi]

him, them

When unstressed, both these pronouns are commonly reduced to [ǝm]. You may sometimes see this spelled 'em in dialogs, cartoons, advertising, etc. when the slang spelling is used for humor or to reflect exactly how someone speaks.

____________

Let him/them go.[lɛ̀ɖǝmgóʊ̯] I don't know him/them. [aɪ̯ɖoʊ̯nt̚.nówǝm] Go to him/them. [góʊ̯ɖuwǝm]

her

1 When unstressed, this pronoun sounds exactly like the ending -er [ʀ]. For instance, in the first example, let her sounds exactly like letter.

____________

Let her go.

[lɛ̀ɖʀgóʊ̯]

I don't know her. [ɪ̯ɖoʊ̯nt̚.nówʀ] Go to her. [góʊ̯ɖuwʀ]

2 As a possessive pronoun, unstressed her is commonly pronounced [ʀ] too.

____________

She came with her mother.[ʃikʰèɪ̯m wɪθʀmʌ́ðɚ]

Note, however, that after a word ending in [r], the initial [h] is usually restored:

She came for her mother.[ʃikʰèɪ̯m fʀ.hʀ.mʌ́ːðʀ]

we'll, we're, we've

The contractions we'll and we're are commonly pronounced [wɪɫ] and [wɪr], especially when completely unstressed. However, we've is always pronounced [wiv].

[pʰɪ̀kǝnʌθʀ múːvi | wiv.síːn ðæ̀t̚wʌn]
