Real-Time Speaker Verification with a Microphone Array

- Real-time speaker verification, with speech acquired using the NIST Mk-III microphone array and an autodirective beamforming algorithm, is demonstrated. The software and hardware backbone of the demonstration is the NIST Smart Flow System and Mk-III Array, both developed by National Institute of Standards and Technology in support of multimodal research communities. A microphone array acquires speech signals; a steered response beamformer calculates the direction of arrival (DoA) of the dominant signal; and a speaker verification component determines whether the signal is speech from a specific privileged speaker. If so, a camera will slew to the DoA of the privileged speaker; but not other speakers, or other kinds of sound. Novel approaches were taken to the design of the basic components to obtain good realtime demonstration performance.
