function [gci,goi] = dypsa(s,fs)
%DYPSA   Derive glottal closure instances from speech [gci,goi] = (s,fs)
%   Note: Needs to be combined with a voiced-voiceless detector to eliminate
%   spurious closures in unvoiced and silent regions.
%
%   Inputs:
%   s     is the speech signal
%   fs    is the sampling frequncy
%
%   Outputs:
%   gci   is a vector of glottal closure sample numbers
%   gco   is a vector of glottal opening sample numbers derived from
%         an assumed constant closed-phase fraction
