| Sumario: | The similarity in twins’ voice has always been an intriguing issue in forensic speaker matching, and has become an important research matter recently. The present work is a preliminary study of exploratory character diving into the similarities of monozygotic (MZ) and dizygotic (DZ) twins’ phonation under the point of view of vocal fold biomechanics. The study extends to other siblings’ and unrelated speakers’ phonation. Estimates of biomechanical parameters obtained from vowel fillers are used to produce bilateral matches between MZ and DZ twins and siblings, and unrelated speakers. These results show interesting relationships regarding genetic load and ambient factors in the adoption of phonation styles. |
