For decades science fiction movies have been imagining the future as one where humans talk to machines just as naturally as they speak to family and friends. In reality, however, using voice to interact with machines has been maddeningly frustrating, with Siri often mistaking “open up my email” for “look up some kale,” for example. This is changing. Increasingly the experience of speaking to your mobile device elicits genuine surprise when Siri or Google Now understands your request and seamlessly executes your request. Put simply, voice recognition in machines is getting very good and is going to get so good that it will completely change the way humans interact with their computing devices.
