What it does

Amazon Lex is AWS's service for building conversational interfaces using voice and text, powered by the same deep learning technology behind Alexa. Developers define intents, slots, and fulfillment logic, connecting to AWS Lambda and CloudWatch. It's priced purely pay-as-you-go per text or speech request, with no platform subscription fee.
