What are recovery prompts in low-confidence?

Recovery prompts at low-confidence are special replies or actions in natural language processing (NLU) and dialogue systems that are activated when the model or system is unsure about the correctness of recognizing the user request.

When the confidence score of the model is low, the system can:

• Ask a clarifying question to the user to obtain additional information.
• Offer options to choose from to narrow down the possible interpretations.
• Ask to repeat or rephrase the request.

This helps improve interaction quality, avoiding incorrect responses and enhancing user experience through active clarification of user intentions.
