In this project, we will use the Peterson and Barney’s dataset of vowel formant frequencies to perform classification. (For more info, look at http://speech:ucsd:edu/aldebaro/papers/klautau02_pbvowel.pdf. More specifically, Peterson and Barney measured the fundamental frequency F0 and the first three formant frequencies (F1-F3) of sustained English Vowels, using samples from various speakers. The dataset can be found in my Github as PB_data.npy, In the dataset we have 4 vectors (f0s-f3), containing the fundamental frequencies (F0, F1, F2 and F3) for each phoneme and another vector “phoneme_id” containing a number representing the id of the phoneme.
