Imagine a phone conversation without actually speaking. Ambient Corporation which developed a device called Audeo recently demonstrated a public voiceless phone call at a conference. It uses a neckband that translates thoughts into speech by relaying signals wirelessly to a computer that converts them into words spoken by a computerized voice.
What if you don’t want to voice exactly what you’re thinking? Well, according to the developer, producing signals for the Audeo to decipher requires "a level above thinking". Users must think specifically about voicing words for them to be picked up by the equipment.
Now there’s no need to fear people eavesdropping in on your phone conversations or being disturbed during a movie or while studying at a library. The overall benefits, however, would be best utilized by patients suffering from a form of neurological or speech impairment.
