The document discusses the rise of conversational interfaces using bots and virtual assistants. It notes that 45% of end users prefer chatbots for customer service and the voice recognition market will be $601 million by 2019. The interface of the future will involve applications that can talk, converse in human terms, understand context and get smarter over time. Both voice-based and text-based conversational interfaces will be used. Voice is a natural interface but challenges remain around whether these systems solve real problems and whether the natural language processing is advanced enough. Microsoft tools like LUIS and Bot Framework are demonstrated as ways to build conversational interfaces.
