Lesson 24: How Can AI Be Applied to Improve Customer Service and Chatbots?
Lesson Objective:
To help learners understand how AI enhances customer service — through faster responses, 24/7 availability, personalization, and cost-efficiency — and how chatbots are becoming increasingly intelligent.
Why Customer Service Needs AI
Modern customer service faces challenges like:
-
High volume of customer queries
-
Rising customer expectations for speed and personalization
-
Shortage of human agents
-
Pressure to reduce support costs
-
Need for 24/7 service across time zones and channels
AI helps address these challenges by acting as a smart front line, handling routine requests and improving the human agent experience.
What Are AI Chatbots?
AI chatbots are intelligent programs that interact with users through:
-
Text (chat windows, messaging apps)
-
Voice (IVR systems, smart speakers)
-
Multimodal (text + voice + visuals)
These bots use natural language processing (NLP) and machine learning to understand, interpret, and respond like humans — in real time.
