I think Google has pretty good deep learning-based word prediction for their Swype-style Android keyboard. There was a period, maybe 1.5 years ago, during which text input prediction got substantially worse, then gradually improved. Along with the change came the ability for text input to change the estimated word after you entered the next word, using the combination of your entries to both words to estimate both simultaneously. If they have language models which perform that task at a level worth pushing out to consumers they can do some smoothing of entries in a list.
