To continue innovating their banking mobile application experience, BBVA Mexico designed “Blue,” a virtual assistant that enables financial transactions to be made by voice and text. Thanks to this experience, we can provide closer assistance and self-service to 10.7 M people. The users of BBVA are very diverse, both in terms of age, income, and experience with technology. Blue allows them to interact through a chat window in the application with voice and text, enabling new forms of usage to decide which is best for them. We had a great challenge because it was necessary to consider the linguistic variety of our country and design the training of the AI and the conversations that would impact the vast majority of the users, regardless of their social, educational, or geographical conditions.
