+\chapter{Limitations}
+    This chapter describes the limitations of the SmartEating chatbot.
+    
+    \section{Audio limitations}
+        For optimal performance, users must speak loudly and clearly when interacting with the chatbot. 
+        This ensures accurate audio transcription and reduces the likelihood of misinterpretations.
+
+        The assistants may struggle to transcribe the audio recorded in noisy environments effectively.
+        For the best experience, users should use the application in a quiet setting to avoid background noise interference.
+        
+        A quiet environment is also required for the assistants to pick up when the user stops speaking.
+
+    \section{Recipe selection limitation}
+        Once a recipe is selected within the chatbot, it cannot be changed.
+
+    \section{Language limitations}
+        The chatbot currently supports only English for both text messages and audio messages.
+        Therefore, users should only interact with the chatbot in English.
