Phoneme {fds} | R Documentation |
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).

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".
