Target-locus scaling for modeling formant transitions in vowel + consonant + vowel utterances

Abstract

The coarticulatory effects described by Öhman [J. Acoust. Soc. Am. 39, 151-168 (1966)] imply that consonant loci cannot always be defined by their associated consonantal contexts alone, but, in Swedish vowel + consonant + vowel utterances, they must also depend on their trans-consonantal vowels (TCVs). His discovery is extended here using a model with TCV-dependent consonant loci and with a unique target for each vowel. The model accurately characterizes the vowel-to-consonant and consonant-to-vowel transitions for the /b/ and /d/ contexts from Öhman's second formant-frequency data as families connected by linear-scaling relationships.
