A method is proposed to estimate individual vocal tract parameters based on formant frequency patterns. Vocal tract parameters, such as scaling factors of vocal tract length and area were determined in reference to the given area function of an articulatory synthesizer: deviations of a speaker's formant frequency pattern relative to the reference speaker are attributed to length and area perturbations of the reference speaker's area function. In the present study the approach, already tested with synthetic speech (2), is extended to natural speech. Investigations are carried out with speech samples from a German language data base to find speaker-specific parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
