An “auditory eigenfunction” approach is provided for auditory language design, implementation, and rendering optimized for human auditory perception. The auditory eigenfunctions employed approximate solutions to an eigenfunction equation representing a model of human hearing, wherein the model comprises a frequency domain bandpass operation with a approximating the frequency range of human hearing and a time-limiting operation in the time domain approximating the time duration correlation window of human hearing. The method can be used to implement entirely new auditory languages, or modification to existing auditory languages, which are in various ways performance optimized for human auditory perception, either with or without the constraints of human vocal-tract rendering. The method can also be used, for example, to implement traditional speech synthesis, and can be useful in speech synthesis involving rapid phoneme production. The method could also be used to implement various other types of user machine interfaces.
