Mispronouncing a segol or a sheva as a chirik, as in “SHI-hakol” or “asher kidEEshanu” seems to be a uniquely American mistake – I have never heard an Israeli or a Brit say it like that.
Another bad mistake leading to an opposite meaning similar to “bal gevuros” is “oyev amo yisroel”, missing out the heh in oyHev.
