Problem

Vivo needed to interpret customer questions across many service channels while keeping response times low during peaks in demand.

Approach

Vivo launched Aura in February 2018 and used Microsoft AI services to develop and scale it. Bot Framework supported deployment across channels, while language-understanding services classified customer intent. A team of former call-center agents reviewed interactions to improve the models.

Results

Takeaway

Human agents continued to support the assistant by reviewing ambiguous questions and training its language models. The reported interaction volume did not measure resolution rates.
