The hopeful summary on voice technology from Digiday ends on a somewhat low note: It's hard to get return users on voice apps. In fact, only 3 percent of those who used Google home app skills in late December were actively using these skills in the second week. Holiday effect? Maybe. This trend signals a utility problem. Technologies take off because they help us save time, money. Or they entertain us. No matter what the creative wrap around a voice technology might be, it needs to do these things efficiently or it will not stick.
