"e" in "investment" same to "u"

>>For the record, I have something in between [1] and [@] for the first vowel of "Kentucky" and "continue." One word where I know I consistently use [1] in normal conversation is in relatively unstressed "just."

"I'm just gonna eat now"
[aIm dZ1s "gVn@ it n{U] <<

Thank you, Kirk!


Am I to understand that any weak vowel can be [@] or [1]?

Not necessarily, as some reduced vowels have to be [I] or either [I] or [1] in many North American English dialects, such as in my -"land" for countries and my -"son"/"sen"/"sson" for surnames examples for my dialect, and *cannot* be [@] at all whatsoever.
