Li Pengcheng

Li Pengcheng is a Beijing-based builder focused on deaf speech rehabilitation and one of the contestants interviewed in 把7位黑客松选手请进播客｜冠军、怪才和48小时不眠的野心家. The podcast used a sign-language interpreter during his segment.

His team built Kenan Voice Changer, an AI voice-repair project meant to make unclear speech easier for others to understand. Pengcheng says doctors once suggested he might need ten years or even a lifetime to learn speech, but he did not want life to be consumed by rehabilitation; the product is meant to help communication during the learning process.
