Amazon Lex announces support for multi-valued slots

Amazon Lex is a service for building conversational interfaces into any application using voice and text. With Amazon Lex, you can quickly and easily build sophisticated, natural language, conversational bots (“chatbots”), virtual agents, and IVR systems. Today, Amazon Lex introduces multi-valued slots. A slot is used to capture user responses as the bot gathers information to fulfill a user request. In some cases, the information can be a list of multiple values. For example, when conversing with an insurance bot, a customer may request quotes for insurance premiums. When the bot requests them to specify which insurance type, the customer may respond with more than one type and say “I need quotes for home, auto, and boat premiums.” With multi-value slots, Amazon Lex can now capture the customer’s response in a single response with no special coding required.
