The challenge in creating conversational AI applications lies in siloed and slow workflows due to inadequate tooling, a problem BMW addressed by using Voiceflow for prototyping their Intelligent Personal Assistant (IPA) voice dialogs. With Voiceflow, the BMW team reduced prototyping time by 50% and successfully designed and tested complex conversations. The company aims to integrate Voiceflow into its series development tool landscape in 2022, as part of its efforts to innovate and transform its processes and tools.
