An organization wants a purpose-built AI solution to increase efficiency and provide personalized interactions for their customer care team. Which Google Cloud AI solution should they use?

Text-to-Speech API converts text to synthesized audio and is a single-purpose component API, not a complete end-to-end customer care AI solution.

Cloud Talent Solution is an AI-powered service for job search and talent acquisition workflows, not for customer care or contact center operations.

Document AI extracts and processes structured information from documents using ML but is not designed for real-time conversational customer care interactions.

Contact Center AI (CCAI) is a purpose-built Google Cloud solution that uses conversational AI to power virtual agents for automated customer interactions and provides real-time guidance to human agents during live calls. It is specifically engineered for customer care use cases, directly fulfilling the requirements of increased efficiency and personalized customer interactions.
