Amazon Lex is an AWS service for building conversational interfaces for applications using voice and text.

With Amazon Lex, the same conversational engine that powers Amazon Alexa is now available to any developer. Developers are enabled to build sophisticated, natural language chatbots into new and existing applications. Amazon Lex provides the deep functionality and flexibility of natural language understanding (NLU) and automatic speech recognition (ASR). NLU and ASU allows you to build highly engaging user experiences with lifelike, conversational interactions and create new categories of products.

Amazon Lex enables any developer to build conversational chatbots quickly. With Amazon Lex, deep learning expertise is not required to create a bot, you just specify the basic conversation flow in the Amazon Lex console. Amazon Lex manages the dialogue and dynamically adjusts the responses in the conversation. Using the console, you can build, test, and publish your text or voice chatbot. You can then add the conversational interfaces to bots on mobile devices, web applications, and chat platforms (for example, Facebook Messenger).

Amazon Lex provides prebuilt integration with AWS Lambda, and you can easily integrate with many other services on the AWS platform, including:

  • Amazon Cognito
  • AWS Mobile Hub
  • Amazon CloudWatch
  • Amazon DynamoDB

Integration with Lambda provides bots access to prebuilt serverless enterprise connectors to link to data in SaaS applications, such as Salesforce, HubSpot, or Marketo.
