The open quotient (OQ), loosely defined as the proportion of time the glottis is open during phonation, is an important parameter in many source models. Accurate estimation of OQ from acoustic signals is a non-trivial process as it involves the separation of the source signal from the vocal-tract transfer function. Often this process is hampered by the lack of direct physiological data with which to calibrate algorithms. In this paper, an analysis-by-synthesis method using a codebook of… CONTINUE READING
