Any time Dr. Raja Kushalnagar steps into a store, he pulls up the Google Live Transcribe app on his phone. Developed through a collaboration between Google and Gallaudet, the app 鈥� which was released in 2019 鈥� activates with a single tap. He can read what a hearing sales clerk is saying. He can type out a reply. He can see the beeps as his order is rung up. 鈥淚 use it every day. It鈥檚 reliable, fast, and easy,鈥� he says. 鈥淚t鈥檚 changed things.鈥�

With over one billion downloads and counting, the app has changed things for a whole lot of people. And it鈥檚 proof that there is a huge demand for products made with deaf users in mind, says Kushalnagar, director of the B.S. in Information Technology and M.S. in Accessible Human Centered Computing programs.

The app began as an internal prototype for a deaf Google engineer who doesn鈥檛 sign, explains Dr. Christian Vogler, Director of Gallaudet鈥檚 Technology Access Program (TAP). When a Google team including the engineer visited campus, Vogler and his colleagues immediately recognized the potential for this kind of product. 鈥淲e said that there鈥檚 a wide need for this and we need to figure out how to release this to the public,鈥� he says.

Working with Gallaudet to develop the app made sense. 鈥淭his is the place where deaf experts get together. It鈥檚 a hub,鈥� Kushalnagar says. The community not only offers a concentration of talent, but also perspective.

The TAP team, including Vogler, Kushalnagar, Norman Williams, Paula Tucker, and Linda Kozma-Spytek, helped test the app, and shared research on which features would be most critical for deaf users. 鈥淚t can detect if someone calls your name, like at a doctor鈥檚 appointment,鈥� Vogler notes. It also shows how much background noise is present and indicates with icons when there is wind, barking, or clapping, Kushalnagar adds.

Loaded with over 80 languages, the app has made all kinds of situations more accessible to people around the world, whether it鈥檚 a guided group tour, an airplane announcement, or a video without captions. 鈥淪imply have a phone and you can be so much more confident,鈥� Vogler says. Instead of relying on hearing people to write down what they are saying, the app produces a full transcript. Even in situations with interpreters, he adds, it can be helpful to have as a backup or a way to check their accuracy.

It鈥檚 proved especially popular in hospital settings with elderly patients, says Kushalnagar, who notes that many of the app鈥檚 reviews credit it for allowing relatives to communicate.

People on both sides of conversations through the app have been impressed by the technology. 鈥淗earing people were skeptical of automatic speech recognition,鈥� Vogler says. Google Live Transcribe has changed minds 鈥� and helped convince competitors to jump in with their products, making live transcription increasingly available.

As the field advances, Gallaudet plans to remain on the forefront of research. 鈥淭here are a lot more things happening here than people realize,鈥� Vogler says.
