Abstract
This paper describes an eigendecomposition based approach to estimate the direction of arrival (DOA) of speech or noise sources in a reverberant room using a microphone array. Unitary ESPRIT (estimation of signal parameters by rotational invariance techniques), a DOA estimation algorithm for narrowband signals, is applied to these wideband signals, resulting in DOA estimates for each frequency. A single estimate is then obtained by means of a histogram. The estimated DOAs of the speech source are used to enhance a noisy speech signal by means of a superdirective beamformer. Experiments in a noisy reverberant room showed a higher estimation accuracy, and thus a better speech enhancement performance, at low SNRs compared to other DOA estimation techniques.
