|
This paper describes a dataset of formant patterns measured in the steady-states of recorded Japanese vowels. Five adult, male, native speakers of Japanese were selected from the "ETL-WD-I and II" balanced word dataset; and for each of the five vowels /i, e, a, o, u/, 22 different words were selected on the basis of consistently finding the lengthiest and most steady-state vocalic nuclei. A semi-supervised method based on linear-prediction (LP) analysis of the speech waveform was then used to carefully extract the first four formants in five consecutive frames of each vocalic nucleus, thereby yielding a total of 2750 patterns of formant frequencies {F1, F2, F3, F4} and formant bandwidths {B1, B2, B3, B4}. These formant patterns are offered in electronic form, with the aim of contributing to the small but growing body of publicly available formant data.
