I've known my wife for five years now, and I still struggle to remember her phone number. The only numbers I know are those I can recall from before getting my first mobile phone, and since I have lost touch with nearly everyone from back then, that has largely been reduced down to immediate family members. For everyone else, there's a People app, and all I've had to do to dial them is start typing their name.
Perhaps the most time-saving key on the Android keyboard is the microphone, but using it is more hassle than it's worth when certain words just refuse to be recognized. More often than not, these words are contact names. Luckily, there is a way to trick your phone into recognizing even the most tongue-twisting of names. If you're tired of your phone turning "Demonte Jones" into "Demon's bones," just teach it to recognize the latter as the former.
