Abstrakt
This paper investigates usefulness of the global rhythm metrics (such as %V, ΔC, PVI, Varco, etc.), introduced by Ramus et al. (1999), Grabe & Low (2002) and others, for speaker identification purposes. In our sample of three Czech female speakers, these features failed to capture the inter-speaker differences satisfactorily.
They are furthermore put in comparison with a local articulation rate (LAR) measure (Volín, 2009), which is shown to be capable of capturing phrase-final lengthening differences between all speakers.
