There have been many advancements in speech-to-text in the last few years. I’m sure that I’ll probably speaking these posts instead of typing them in the next few years, provided I’m not disturbing others in the room.
I’m sure that the hearing impaired would most benefit from speech to text technology, and this is what the Babel Fisk is supposed to do.
Designed by Mads Hindhede, the Babel Fisk has microphones built into the frame in order to pick up the voice of a person in the line of sight, and then an embedded speech-to-text program will create the text that is projected inside of the lenses.
You can even program it to record the text to a flash memory card for later use. So you can literally record everything that you hear as a text file.
