Description

Multivariate time series (MTS) indicating voice recordings of nine Japanese male speakers saying the vowels 'a' and 'e'.

Usage

data(JapaneseVowels)

Format

A list with two elements, which are:

data

A list with 640 MTS.

classes

A numeric vector indicating the corresponding classes associated with the elements in data.

Details

Each element in data is a matrix formed by 29 rows (time points) indicating time recordings and 12 columns (variables) indicating modified raw recordings. The first 270 elements correspond to the training set, whereas the last 370 elements correspond to the test set. The numeric vector classes is formed by integers from 1 to 9, indicating that there are 9 different classes in the database. Each class is associated with a different speaker. For more information, see Bagnall et al. (2018). Run "install.packages("ueadata1", repos="https://anloor7.github.io/drat")" to access this dataset and use the syntax "ueadata1::JapaneseVowels".
