The LSF parameters were transformed to the square-root Δ LSF domain and we modeled the underlying distribution by a von Mises–Fisher mixture model (VMM).
In this paper, we present the LSF parameters by a unit vector form, which has directional characteristics. The underlying distribution of this unit vector ...
