We created a simple Alexa skill, created a Lambda backend, linked both together, and tested it using the Echo device (or a simulator). You can now publish Alexa skills and get rewarded by Amazon through its Alexa promotional programs.

Amazon Lex is not just restricted to conversational interfaces that use voice inputs; it can also be used to build custom non-voice conversational interfaces, such as chatbots. Since the backends for both an Alexa skill and Lex-based chatbots can both be lambdas, you can reuse the same backend logic for both Alexa and a chatbot.

 We created Alexa skills using ASK CLI. However, you can also use the developer portal to create and test Alexa skills easily. You can also explore the voice app platforms that make Alexa skill development even more easy.
