Conversational technology allows people to get information, conduct transactions, and be entertained, simply by speaking to a computer. Based on the integration of speech recognition, natural language processing and dialog understanding, conversational systems are rapidly becoming an important component of solutions such as virtual assistants, customer care, and the Internet of Things. These systems save money and time, attract new customers, and improve accessibility for their users on a day in and day out basis for millions of people all over the world.

Conversational Technologies can help you get started in applying these technologies to your problems.
