Language / Slavic accent correction [110]

Hi Vlad, I was informed that the neuro-muscular system in ones mouth prevents for any changes in speech after certain age,i.e. children can make easily changes and even teens,

but adults will have very hard time to do that.I came to the States at rape age of 42 and after 30 years of living in the country have still Polish accent,even though had tried to work with the speech teacher to improve but to no avail.
