For Singapore’s deaf and hard-of-hearing community, something as simple as picking up the phone can feel impossible. With only seven full-time interpreters serving thousands, making a doctor’s appointment or calling a hotline often means relying on family, friends, or long waits.

Enter CallBridge — a homegrown innovation using real-time text-to-speech and speech-to-text to let users make calls independently, privately, and with dignity. On Good Tech, Lynlee Foo speaks with co-founders Yeo Shi Tan and Cody Tan De Xuan about building CallBridge during a hackathon, the impact of its pilot programme, and their vision to integrate it into essential services like emergency hotlines.
