h95: Hillenbrand et al. (1995) Vowel Data

Description

Formant frequency, f0 and duration information for vowels collected from 139 speakers in the Hillenbrand et al. (1995) data. Speaker numbers have been modified to be uniquely identifying numbers. Data has been simplified so that only "steady state" formant frequency measures are given. Missing F2 values (n = 10) and F3 values (n = 41) have been imputed using the imputeformants() function included in this package.
