Carolina is a voice assistant developed with generative AI to modernize and optimize customer and post-sales attention processes in a laboratory branch that manages thousands of monthly queries. Unlike traditional systems, Carolina is an intelligent, natural and bidirectional voice, capable of maintaining fluid conversations, understanding nuances, responding with precision… and being interrupted at any time without losing the thread. In this project, Carolina allows querying the status of orders, arrival dates, clinic information and operational data immediately and without human intervention.

Challenges

Fragmented user experience: Customers had to manage queries through multiple manually attended channels, generating irregular waiting times and a lack of standardization.
Manual processes: Previous solutions were manual, affecting the quality of other services.
Complex integration with internal systems: The client operates with an internal CRM that required precise, secure and real-time integration.
Multilingualism and scalability: The laboratory receives queries in multiple languages and needed a tool capable of adapting to different accents and markets.

Key Success Factors

Hyperrealistic voice and bidirectional

The ability of Carolina to maintain natural conversations, with intonation and human rhythm, was decisive to achieve immediate adoption by users.

Dynamic interruption in real time

Allowing the user to interrupt, correct or change topic without breaking the experience was one of the most innovative and differentiating elements of the project.

Deep integration with corporate systems

The connection with the internal CRM Carolina would respond with updated and precise information, consolidating its practical usefulness from the first day.

Optimized multi-agent architecture

The use of specialized agents (data, voice, reasoning, conversation) guaranteed fast, consistent and highly reliable responses in different scenarios.
