A new Google Glass app makes it easier for people with hearing impairments to understand what someone is saying by captioning the conversation.

Georgia Institute of Technology released the Captioning on Glass app, which is meant to caption conversations in real time to help people with hearing impairments.

Google Glass can't accurately pick up external voices at this point, so it links with a free Android app allowing the person talking to the Google Glass wearer to speak into the phone's microphone. Instead of trying to read lips or have a person speak more loudly, the Google Glass wearer can hand their phone to the person they're talking with and read the conversation as it happens.

Users can also read back over the conversation for anything they missed. The same team is also working on an Android app that provides two-way translations for English, Russian, Spanish, French, Korean and Japanese and can link to your Google Glass.
