Vowel Recognition (Deterding data)

Description

Speaker independent recognition of the eleven steady state vowels of British English using a specified training set of lpc derived log area ratios. The vowels are indexed by integers 0-10. For each utterance, there are ten floating-point input values, with array indices 0-9. The vowels are the following: hid, hId, hEd, hAd, hYd, had, hOd, hod, hUd, hud, hed.

Usage

Format

A data frame with 990 observations on 10 independent variables, one nominal and the other numerical, and 1 as the target class.
