Determination of chaos in human vowels
Casey R. Winkel, P. G. Vaidya · The Journal of the Acoustical Society of America · 1995
Human speech is a topic of much study today and many aspects of human speech are still unknown. The existence of chaos in a sustained vowel is one example. An analysis of the time series data generated by human speakers will be performed to determine if the data are chaotic. A set of pseudostate vectors will be created and used to analyze the time series data. From this analysis the largest Lyapunov exponent and the fractal dimension will be estimated. Also, support of a nonlinear origin of speech will be provided.
