Sitone is a pronunciation training tool that helps Chinese learners quickly pickup the basic four tones in Chinese Mandarin. The device combines digital interface with tactile feedback, creating an engaging learning environment. 

 
 

Why is learning chinese hard?

In English, the tone or the pitch of your voice usually conveys a feeling or an emotion. However in Chinese Mandarin, tones are used to distinguish the meanings of words. For example, mà(scold) is very different from mā (mother). In addition, each tone in Mandarin doesn't have a specific pitch, instead it is identified through the change of pitches (as explained by the music notes above).

User Testing

During my brainstorming, prototyping and user testing stages, I quickly mocked up several prototypes and invited people to interact with my models. For each subject, I asked them to: 

1. Pick a prototype based on look, feel and ergonomics.

2. Pick a Chinese phrase from the testing booklet.

3. Interact with the device and try to pronounce the Chinese characters. 

 

Although none of my test subjects speak Chinese Mandarin fluently, most of them were able to successfully finish the task with the assistance of the device they picked (32 out of 40). More than half of my test subjects thought the device (24 out of 40) was helpful.

After comparing my testing results and user comments, I decided to choose the book strap for my final design because it is intuitive to use, small and compact and it also attaches to books without falling out.
