it is "describe", not discribe. Discribe is how it is pronounced by many speakers, some people will say the "e" sound and others will not, they say it as "i".
I say both. deliberately changing to "e" describe, when in educated or higher class company, and "i" discribe when in lower class company of the poorer East End of London where I live.
Hi!
I think you're right, it happens around the world. But in the most developed countries you would see the other side of it.
