Euclidean Distances as measures of speaker similarity including identical twin pairs: A forensic investigation using source and filter voice characteristics

The human vocal apparatus is a sophisticated system relying on the accurate synchronization of multiple organic structures (e.g. lungs, vocal folds, vocal tract) in order to produce speech. Researchers from diverse disciplines have approached this field from very different angles, and continue contributing to the understanding of this immensely complicated process. Traditionally, the structures involved in speech production have been separated into the systemic view of the source-filter model due to Gunnar Fant [1], where the laryngeal structures are credited for the production of phonation, and the supralaryngeal structures are credited for modifying phonation spectral contents dynamically.
