joeysvowels: Datasets based on my speech

#' Vowel formants from 11 Idahoans
#'
#' A dataset containing information on 1,100 vowel tokens produced by 10 people
#' from the state of Idaho in the United States. For each speaker, there are
#' ten tokens per canonical monophthong, randomly selected from a larger
#' dataset. Vowels are not preceding sonorants and not following coronal
#' consonants. For each token, F1, F2, F3, and F4 were extracted at the midpoint
#' of each vowel using a Praat script. The individuals consented to their data
#' being used in this way.
#'
#' This dataset is useful for testing and demonstrating vowel normalization
#' functions.
