Amazon Lex improves conversational accuracy with LLM-Assisted NLU

Amazon Lex now offers a Large Language Model (LLMs) assisted Natural Language Understanding (NLU) to improve intent classification and slot resolution capabilities for English and Spanish locales. This feature allows you to leverage Large Language Models (LLMs) to enhance accuracy when the standard NLU encounters challenges, helping you deliver more natural, resilient conversational experiences, while maintaining complete control over your bot's responses, defined intents, and slots. For example: interpreting complex or lengthy utterances, maintaining accuracy despite spelling errors, extracting slots from verbose inputs, delivering better results with minimal training data and does not require any changes to permissions or integration settings.

This feature is available in all commercial AWS Regions where Amazon Lex operates. To learn more about the assisted NLU or how Amazon Connect and Amazon Lex deliver cloud-based conversational AI experiences for contact centers, please visit the Amazon Connect website.
