fds (version 1.8)

Phoneme: Phoneme data

Description

This data set was formed by selecting five phonemes for classification based on digitized speech. There are \(n=2000\) pairs \((x_i, y_i)_{i=1,...,n}\), where \(x_i\) corresponds to the discretized log-periodograms whereas the \(y_i\) gives the class membership (five phonemes: aa, ao, dcl, iy, sh).

Usage

data(aa)
data(ao)
data(dcl)
data(iy)
data(sh)

Format

An object of class fds.

Details

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".
