Microsoft has announced that it has purchased Semantic Machines, a company that is "advancing the state of conversational AI." This will put Cortana into the position of being the most advanced OS AI that will never be used by most of its owners. Thanks cageymaru. We are excited to announce today that we have acquired Semantic Machines Inc., a Berkeley, California-based company that has developed a revolutionary new approach to building conversational AI. Their work uses the power of machine learning to enable users to discover, access and interact with information and services in a much more natural way, and with significantly less effort. We are further developing our work in conversational AI with our digital assistant Cortana, as well as with social chatbots like XiaoIce. XiaoIce has had more than 30 billion conversations, averaging up to 30 minutes each, with 200 million users across platforms in China, Japan, the United States, India and Indonesia. With XiaoIce and Cortana, we’ve made breakthroughs in speech recognition and more recently become the first to add full-duplex voice sense to a conversational AI system, allowing people to carry on a conversation naturally.
