Speech Compass
SpeechCompass is a new mobile technology that solves the problem of understanding who's speaking in group conversations by using multiple microphones to detect speech direction, making speech-to-text captions more useful for people with hearing challenges. The system displays visual cues like arrows to show where each speaker's voice is coming from, which tests show users find valuable for following group discussions more easily.
