AI-Based Voice Assistants for Automated Customer Care Systems

Abstract

AI-powered voice assistants automate customer support through phone calls using advanced Artificial Intelligence (AI) and Natural Language Processing (NLP). The sys- tem converts spoken customer queries into text using Speech-to-Text (STT), retrieves accurate information using Retrieval-Augmented Generation (RAG), and delivers re- sponses through Text-to-Speech (TTS).  The assistant provides context-aware, real-time, and policy-compliant answers, minimizing the need for human agents. It also allows call transfers to human representa- tives when necessary and logs conversations for future anal- ysis. The system ensures 24/7 assistance, reduces opera- tional costs, and enhances customer experience by deliver- ing consistent, efficient, and intelligent support.
