Amazon Lex allows you to create conversational interfaces in any application by using voice and text. Amazon Lex offers advanced deep learning functions such as automatic speech recognition (ASR), which converts speech to text, or natural language understanding (NLU), which recognizes the intent of the text. This allows you to create applications that are engaging and have lifelike conversations. Amazon Lex gives developers the same deep learning technology that powers Amazon Alexa. This allows them to quickly and easily create sophisticated, natural-language, conversational bots ("chatbots") with ease. Amazon Lex allows you to create bots that increase productivity in the contact center, automate simple tasks and improve operational efficiency across the enterprise. Amazon Lex is a fully managed service that scales automatically so you don’t have to worry about infrastructure management.
