connected speech.it confuse me when speaking
Yes, it does. You understand that the usual pronunciation in American English might differ from the pronunciation in automated translation services. We hear “him” / hɪm / in the automated translation but something more like “herm” (with a neutral vowel / həm / ) is what we expect to hear in connected speech in the typical American accent. In rapid conversation you may also hear, “Do I know ’əm?”.
To illustrate this, in this video the first person speaking says (at 0:35) “...I can’t speak for how the rest of the world relates to him...”. Here the word “him” is pronounced with a neutral vowel / həm /.
This may be a common American pronunciation but is not the only possible pronunciation in all American dialects and in all contexts. It is also worth noting that a neutral vowel in this situation is a common feature of some other English dialects including Australian English.
