Here is a list of some elisions that may occur in informal speech. You are not expected to apply these in your own speech.
1. Elision of pre-consonantal /v/ is common in the weak forms of of and have, as in (I can take) care of myself /ˈkɛr ə maɪˈsɛlf/, (in my) neck of the woods /ˈnɛk ə ðə ˈwʊdz/, (You) should have seen (her) /ˈʃʊd ə ˈsiːn/. In informal writing, spellings like kinda, shoulda for kind of, should have are sometimes used to reflect this type of elision.
2. In rapid styles, /ð/ may be realized as a dental nasal [n̪] after /m/, as in from there, from this: /frəmˈn̪ɛr, frəmˈn̪ɪs/.
3. Elision of /f/ is common in fifth, twelfth.
4. Before unstressed me, the verbs let, give lose their final consonant in informal styles: /lɛmi, gɪmi/.
5. In very rapid styles, flap deletion may occur, as in better /bɛər/, greatest /ˈgreɪəst/.
6. Finally, note that /k/ is normally elided in asked and /g/ frequently in recognize.
