I heard in numerous cases the following syllables pronounced unrecognizably.
In many pronunciation websites, they teach when there's no stress in the underlined vowels, they change to schwa(neutral sound, not ə but the sound as in tomorrow when o sound disappears)
but they seem to pronounce these as "ɪ" or "ʊ", did I mishear them? There might be some difference between AE and BE, and I'm afraid if I can learn correctly through writing explanation not sounds in this website.
ex)Electrical, Eleven, Event
