During my internship at DiDi, I worked on various projects to enhance the driver experience with voice user interfaces (VUI), including user research, designing and prototyping VUI, scripting AI voice text-to-speech, and collaborating with an engineer to update VUI in an autonomous car. Although I'm unable to provide further information due to an NDA, drivers expressed positive feedback about the driver-to-passenger instant voice messaging feature during random interviews, which was launched after my internship ended:
"Now [with instant voice messaging] passengers can speak and drivers can directly reply. It's a great feature."
"After [using the instant voice messaging feature to] directly communicate with the passenger, which they usually cancel, the chances of the passenger canceling the order are lower."
Here are the key lessons I learned during my experience:
- Execution: Always ask "why". Understand the context and focus on end goal, rather than just completing tasks.
- Planning: Keeping an overall perspective on multiple projects is crucial to ensure that all tasks and objectives are aligned and on track.
- Communication: When facing constraints and limited resources, strive to identify shared objectives and priorities to ensure alignment and effective collaboration across different departments.
