Conversational English Practice Bot



Product Lead: Yours truly / UI-UX Design: Yours truly / Dev: Luciano L, Andy J

Through the vigorous feedback loop in our previous project, we picked up on a common issue amongst our users. They told us that they didn’t have a way of practicing their spoken English. 

We addressed the user’s need for a safe space to practice speaking with the app DAKA (Chinese for punch card). Users “punched into” the app to speak with our conversational bot via voice messages in a chat interface. The topic “cards” were refreshed daily, and fostered discussion on a number of trending issues such as the latest Marvel movie or Donald Trump. Post-conversation, users had the option of submitting their recordings to our team in the Philippines to get feedback on their oral English skills. 

This service is currently running in Beta.

The key decision was made early on take the majority of the user workflow and put it directly onto the chat interface. The user has a mostly linear path, so we wanted to take functionalities that would traditionally be invoked by sliders, buttons and views, and make it feel more organic. This made the experience extraordinarily streamlined and provided context for key user actions. We offered functions exactly when they were appropriate and provided explanations for the user at every step of the way. This thinking dictated how every major functionality manifested in the app. 

For example, one core interaction is the request and delivery of feedback from our corrections team. The service was offered via a message from the bot after users completed their daily exercise. Completed feedback would be sent back to the user in the same chat room. Traditionally realizing a feature like this would have taken multiple views and scene changes, but we did it all in one chat conversation flow.
