Among the many announcements of Google I / O 2019 assistants, the new accessibility features are perhaps the most heartwarming. One of these, designed for the many deaf or hard of hearing, is called Live Caption, a subtitling service that displays a transcript of what is said in a video, video call or even an Instagram story in real time. .

From the demo we saw a lot of applications. Whether it's helping deaf people to understand a YouTube video, podcast or chat in Duo mode, Live Caption works with Live Transcribe to help those who might not be involved in the content or other persons in digital form. It runs entirely on your device without the need for the Internet, takes only 80 MB of space and is activated by a simple button in the Volume menu.
