#' @description Multivariate time series (MTS) indicating voice recordings of nine Japanese male speakers saying the vowels 'a' and 'e'.
#' @usage data(JapaneseVowels)
#' @format A \code{list} with two elements, which are:
#' \describe{
#' \item{\code{data}}{A list with 640 MTS.}
#' \item{\code{classes}}{A numeric vector indicating the corresponding classes associated with the elements in \code{data}.}
#' }
#' @details Each element in \code{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 \code{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.
