AI Based FAQ Chatbot with Voice Assistance of GRIET

Abstract

This proposed system centers around the creation of an AI-based FAQ Chatbot with Voice Assist. This Chatbot allows users to interact with the service using natural voice commands. In the conventional approach, the FAQ section is handled by the support staff, but this system automates the entire process using Artificial Intelligence. Using a browser, the chatbot collects the user's voice data, transcribes the audio using speech recognition, and applies NLP techniques like TF-IDF and cosine similarity to retrieve the most relevant answer from the stored FAQ data. If there is a lack of confidence in answering the question, the input is stored as an unknown answer for administration review and the user input is captured as unanswered questions. These questions can then be reviewed by admins and appropriate responses provided which will allow the admin to refine the stored responses, thus enhancing the system's intelligence. Furthermore, the responses are delivered through text-to-speech outputs which allow users to listen to the answers. By integrating voice commands, responsive intelligent interface, and the admin feedback loop, the system's capability to enhance user experiences and refine self-responding systems through continuous improvement is extraordinary. The proposed system was tested with 496 test queries, comprising of original and rephrased FAQ queries, and the accuracy of response was found to be 97.58% with an average retrieval time of 0.0018 seconds.
