What if we could speak with our devices, cars, and homes just as easily as we do with our friends? Conversation is the bedrock of human communication, a transformative tool that reveals what's inside our heads and hearts. Voice is our primary means of connecting with others--and, increasingly, it's how we want to engage with the machines around us, too. The art of human conversation can be maddeningly difficult for even very sophisticated machines, but we're on a path to creating solutions that are much closer to what we need. Thanks to advances in speech recognition, artificial intelligence, neural networks, and processing power, we can tap into the capabilities of our machines simply by speaking.
