The growing need for efficient and personalized customer service has led to the rise of AI powered voice assistants. These systems utilize natural language processing (NLP) and machine learning to deliver real-time, intelligent support to customers. By mimicking human-like interactions, AI voice assistants provide round-the-clock availability, scalability, and immediate responses to inquiries. This paper examines how AI is integrated into customer service through voice technology, focusing on its advantages, challenges, and future prospects. Notable benefits include shorter wait times, enhanced customer satisfaction, and cost savings for businesses. However, issues like language comprehension, emotional intelligence, and data security still pose challenges. As technology advances, AI voice assistants are anticipated to significantly improve customer experiences, optimize business operations, and facilitate personalized support on a larger scale.
