GraphAudio: GraphAudio is an acoustics start-up featuring a graphene transducer developed at the Lawrence Berkeley National Lab and a contextually-aware voice recognition system from Dr. Julian Chen's lab at Columbia University. The technology forms the basis of an acoustic platform that improves the performance and capabilities of consumer and enterprise electronics. The rapid convergence of smart phones and the Internet has turned mobile devices into the primary point of information flow and communication. GraphAudio’s graphene transducers (microphones and micro-speakers) will replace current microphone and speaker components, providing consumer electronics with superior acoustic performance. The GraphAudio voice recognition software will couple with the microphone in consumer electronics, adding value to affective computing and health monitoring in the era of Big Data and AI.
