WebThe glottal open quotient (OQ) is one rel- evant measurement which is known to signiﬁcantly vary with changes in voice quality on a breathy to tense continuum. The extraction of OQ, however, is hampered in the time-domain by the difﬁculty in consistently locating the point of glottal open- ing as well the computational load of its measurement.
