Live speaker identification in conversations
Gerald H Friedland, Oriol Vinyals · 2008
The following article describes our technical demonstration of an online speaker identification system for conversations. A laptop with an internal microphone is centrally placed in the table of a meeting room. The system is able to identify the current speaker independent of spoken text or language with a latency of about 1.5 seconds and an accuracy of about 85% (as evaluated against the NIST RT benchmark). A Java GUI shows the image of the current speaker along with a timeline containing past speakers. Speakers are added to the system's database using a one-minute training procedure.
