Amazon Lex
AWS service for building conversational interfaces.
Amazon Lex is AWS's service for building conversational interfaces with voice and text. It uses the same technology as Alexa and integrates natively with AWS Lambda, DynamoDB, and other AWS services.
I use Amazon Lex for chatbot projects where the backend is already on AWS. The native Lambda integration means you can build sophisticated fulfillment logic without managing additional infrastructure, and the voice capabilities work well for IVR and telephony use cases.
For businesses already running on AWS, Lex is a natural choice for adding conversational interfaces. It handles the speech recognition and NLU while Lambda functions handle the business logic - order lookups, booking systems, or internal tool queries.
How I use Amazon Lex
For chatbots, it builds voice and text bots with AWS Lambda integration.
