The Problem

d/Deaf and hard-of-hearing individuals in Singapore lack accessible, independent ways to make or receive essential phone calls, especially when contacting businesses, government services, financial institutions or in emergencies. This leads to delays, missed appointments, privacy risks, and exclusion from critical services.

One key challenge is the limited availability of qualified interpreters. Currently, only around 7 full-time interpreters serve over 6,000 individuals in Singapore who identify as Deaf and primarily use sign language. While interpreters and hearing individuals often support communication, existing solutions still heavily rely on them, which may not always meet the needs for privacy, immediacy, or consistent access. As a result, many Deaf individuals face barriers to making and receiving phone calls independently.

Our Solution

A mobile application designed to bridge communication gaps for d/Deaf and hard-of-hearing individuals. The app leverages on speech-to-text (STT) and text-to-speech (TTS) technologies to function as a two-way conversational interface.

When a hearing person initiates a call, their spoken words are transcribed into live text on the screen, allowing the deaf or hard-of-hearing user to read and respond via text. The app then converts the typed response into speech for the caller on the other end.

This enables these users to communicate directly and independently with clinics, banks, emergency services and even their friends!
