TL;DR
Embark’s “Type or Say” feature was redesigned after user testing revealed significant usability issues. Simplifying the interface based on observed inefficiencies led to a 30% reduction in task completion time, enhancing user efficiency and overall experience.
Impact
30% Reduction in Task Completion Time
Testing the redesigned “Type or Say” feature with 8 missionaries showed a 30% reduction in interaction time, highlighting efficiency gains from addressing usability issues and simplifying the interface.
Better Alignment with User Needs
A survey of 50 missionaries revealed a 60/40 preference for typing over speaking. By separating these functionalities, we created a more intuitive interface, improving user satisfaction and better aligning with user preferences.
Background
Embark is a language-learning app designed for LDS missionaries. Within Embark, the “Type or Say” activity allows users to practice typing or speaking words they are learning. During user testing of existing features, I identified several issues with this activity.
Goal
The goal was to find and fix the usability issues in this feature. This would improve the missionary learning experience.
Research
I conducted testing to identify existing design problems in Type or Say. Testing involved common tasks like typing or speaking answers. Observations revealed a cluttered interface and awkward interactions. Specific issues were identified in both typing and speaking modes:
Issues identified
Usage survey
As part of my research, I also wanted to investigate missionaries' answering habits. I sent a survey to 50 missionaries. I wanted to find which answering methods they used most and how often they would switch between them.
Design
Brainstorming
The process began with sketching and wire framing initial ideas. Currently all the controls for typing and speaking are shown on the same page. One idea we kept coming back to was splitting typing or saying into 2 modes you could switch between. This was based on user behavior from our research and allowed for a simpler interface.
Rough initial sketch of the new concept.
Testing
The design was tested with 8 missionaries at the MTC using the same testing method as before. This direct comparison revealed significant usability improvements. Based on the second test, there was a 30% reduction in the time it took users to complete key feature tasks
But, it also brought to light one point that was still confusing.
Solution
Splitting answer method
Separated Typing vs Saying to better align with user's usage and allow a more focused interface for each.
Current design with both answer methods on same page (Left). Updated design with split modes (Right).
Typing improvments
Letterbank improvements
Improved the transition between the letter bank and keyboard for a smoother experience.
The updated design (right) added a clearer way to switch between the keyboard and letter bank.
Speaking improvments
Microphone
Removed the redundant microphone for recording and streamlined the interface.

Conclusion
This redesign successfully addressed usability issues, simplifying the "Type or Say" activity and improving the overall user experience. Through detailed research, thoughtful design adjustments, and thorough user testing, we were able to streamline the interface, resulting in a more intuitive and efficient experience for users.
