The World Health Organization estimates that by the year 2055, there will be 900 million people with hearing loss. We believe in the power of technology to help break down barriers and make life a little easier for everyone. Today, we’re introducing two new apps for Android designed to help deaf and hard-of-hearing people: Live Transcribe and Sound Amplifier.

Bringing captions to conversations with Live Transcribe

Dimitri Kanevsky is a research scientist at Google who has worked on speech recognition and communications technology for the last 30 years. Through his work, Dimitri—who has been deaf since early childhood—has helped shape the accessibility technologies he relies on. One of them is CART: a service where a captioner virtually joins a meeting to listen and create a transcription of spoken dialogue, which then displays on a computer screen. Dimitri’s teammate, Chet Gnegy, saw the challenges Dimitri faced using CART: he always carried multiple devices, it was costly and each meeting required a lot of preparation. This meant Dimitri could only use CART for formal business meetings or events, and not everyday conversations.

That inspired Chet to work with the Accessibility team to build a tool that could reduce Dimitri’s effort spent preparing for conversations. We thought: What if we used cloud-based automatic speech recognition to display spoken words on a screen? A prototype was built and Googlers across a bunch of our offices—from Mountain View to Taipei—got involved. The result is Live Transcribe, an app that takes real-world speech and turns it into real-time captions using just the phone’s microphone.

Live Transcribe has the potential to give people who are deaf or hard of hearing greater independence in their everyday interactions. It brought Dimitri closer to his loved ones—he’s now able to easily communicate with his six-year-old twin granddaughters without help from other family members. We’ve heard similar feedback from partners at Gallaudet University, the world’s premier university for deaf and hard of hearing people, who helped us design and validate that Live Transcribe met needs of their community.
