Spreadlove, Sidster and FF
Thanks for being serious about this topic. It might look nothing but it can lead to embarrassment, some can end up with troubles. All of your examples are classic, FF- yours were really funny. Surprisingly I've picked up Hard Drive (instead of disss :-) )
I've been try to say these words for years and still have long ways to go, made few improvements. I had difficulties with "Shoulder" and "Soldier" and another instance was "Salon" and "Saloon" was being said the same way. I'm still learning "Statistic", which we say like in "Start" is pronounced as "Istatistic" like in "Ista-Mitra" instead. I had a difficult time saying "Umbilical cord" for a while.
One word "FILM" is the most diff ult to say with American accent. We say "FEEEE-LEAM" It is more like "ILM" and the F is so short that it disappears before you can hear it.
