Public presentation training (public speeches, presentations, etc) will help enormously with every day social awkwardness, especially if you do it regularly and in varying ways (don't do the same thing, same speech, to the same people over and over again; if you do the same thing over and over again, you may just be training a sort of fake social muscle memory).

It's quite rare that you can conquer a public crowd but you can't deal with mundane every day social situations (I'm sure there are exceptions, it's just a rare combination).

The memorized speech part isn't ideal over time though. To get started that's fine, however it should be a written speech and intentionally improvized after a few experiences with doing it; and then it should be entirely improvized (and a bit shorter) occasionally as well.
