I love SwiftKey on my iPhone and would never go back to a regular touchscreen keyboard again. However, there is one issue I've had for years that I think could be resolved, and benefiting the user and your company by improving your speech-to-text technology.
My suggestion is to enable speech recognition in conjunction with typing. There are common words that get mixed up constantly, such as "hey" and "get". I'll write "Hey dude, what's the plan?" and SwiftKey types "Get dude, what's the plan?" If I can speak while typing, the app can figure out what I'm actually trying to write, reducing the amount of typos and corrections needed, improperly typed texts sent to others, and improving your speech-to-text technology over time.
