Author: Source: KEEL Please cite: * Title: Phoneme dataset * Abstract: The aim of this dataset is to distinguish between nasal (class 0) and oral sounds (class 1). The class distribution is 3,818 samples in class 0 and 1,586 samples in class 1. The phonemes are transcribed as follows: sh as in she, dcl as in dark, iy as the vowel in she, aa as the vowel in dark, and ao as the first vowel in water. * Attributes information: @relation phoneme @attribute Aa real [-1.7, 4.107] @attribute Ao real [-1.327, 4.378] @attribute Dcl real [-1.823, 3.199] @attribute Iy real [-1.581, 2.826] @attribute Sh real [-1.284, 2.719] @attribute Class {0, 1} @inputs Aa, Ao, Dcl, Iy, Sh @outputs Class
