Abstract:The central frequencies of the principal resonance regions, or formants, have been found to contain sufficient information to resynthesize intelligible speech, as far as vowels and other nonturbulent sounds are concerned. When a single formant is isolated by filtering, one-half the average zero-crossing density, ρ0, is shown to be a convenient approximation to the formant's central frequency. Filters which are controlled electronically by a preliminary approximation to the first-formant frequency, in such a wa… Show more
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.
