Interesting problem can you add more detail on these two points 1. Multiple conversations
More than one operator on a single line? How does this work? 2. Recovering letters from context This is the ultimate goal? Are letters omitted in a consistent formalized way (e.g. can't) or in an informal, individual way (i.e. wut, wht? w?)
