Nasal Consonant Discrimination by Vowel Independent Features.
No full textThis paper describes nasal consonant discrimination based on vowel independent features; murmur and onset spectrum. Classification based on spectral pattern statistics by linear discriminant functions has shown to be quite successful for a specific speaker, but not so good for a non-specific speaker set consisting of 44 speakers. Several experiments were made to determine the influence of individual factors, and some tentative conclusions are drawn
Qualitative analysis of behavior of systems of piecewise linear differential equations with two state variables
No full textAbstractThe set of all solution curves in the phase space for a system of ordinary differential equations (ODEs) is called the phase portrait. A phase portrait provides global qualitative information about how a given system of ODEs behaves under different initial conditions. We are developing a method called Topological Flow Analysis (TFA) for automating analysis of the topological structure of the phase portrait of systems of ODEs.In this paper, we describe the first version of TFA for systems of piecewise linear ODEs with two state variables. TFA has several novel features that have not been achieved before. Firstly, TFA enables to grasp characteristics of all behaviors of a given system of ODEs. Secondly, TFA allows to symbolically represent behaviors in terms of critical geometric features in the phase space. Finally, TFA integrates qualitative and quantitative analysis. The current version of TFA has been implemented as a program called PSX2PWL using Common Lisp
Discriminant Analysis of Burst Spectrum for Japanese Initial Voiceless Stops
No full textWe determined the extent to which the onset spectra of natural CV utterances consisting of [p, t, k] in the environment of five vowels could be correctly classified by the linear discriminant functions. Over 80% of the utterances were correctly classified independent of vowel context and speaker difference. Thus, the spectrum at the burst onset does seem to produce, also in Japanese, an invariant gross shape for place of articulation which Blumstein and Stevens (1979) have claimed
