When you are distressed about a legal matter and call a law firm for assistance, the last thing you want is to talk to an emotionless robot. CaseFlood understands that and in my role here, I enhanced the empathy and context retrieval of the AI-receptionist by applying multiple fine-tuning techniques on the Azure OpenAI Assistant API. The project currently has resulted in decrease in perplexity by 12% , reduced repitition and a warm, empathetic and efficient AI receptionist.
