The Quantititive Estimation of Asynchrony Among Concurrent Speakers

A novel method for the estimation of asynchrony among two speakers reading together is proposed. Previous estimates of asynchrony were based only on the pointwise measurement of lag. We here adapt the well known method of dynamic time warping to align two utterances. The resulting warp path allows a quantitative estimate of asynchrony. Illustrative examples are provided, which demonstrate that the novel method can distinguish synchronization performance in a variety of speaking conditions.
