phonetic: Phonetic data

In multifamm: Multivariate Functional Additive Mixed Models

Description

The data are part of a large study on consonant assimilation, which is the phenomenon that the articulation of two consonants becomes phonetically more alike when they appear subsequently in fluent speech. The data set contains the audio signals of nine different speakers which repeated the same sixteen German target words each five times. In addition to these acoustic signals, the data set also contains the electropalatographic data. The target words are bisyllabic noun-noun compound words which contained the two abutting consonants of interest, s and sh, in either order. Consonant assimilation is accompanied by a complex interplay of language-specific, perceptual and articulatory factors. The aim in the study was to investigate the assimilation of the two consonants as a function of their order (either first s, then sh or vice-versa), syllable stress (stressed or unstressed) and vowel context, i.e. which vowels are immediately adjacent to the target consonants of interest. The vowels are either of the form ia or ai. For more details, see references below.

n_long

Unique identification number for each curve.

t
