Abstract

FIR (finite impulse response) filters are applied using CSL, in the quantization of the SPL amplitude component of linguistic resonant pharyngeal consonants in word-initial CV environments. Only the onset consonant amplitude responses are modelled, with FIR transfer functions corresponding of SPL acoustic responses: glottal excitation (forced response), separate from the pharyngeal transmission (natural response). The FIR transfer function (impulse response) system design has the following properties: pharyngeal transmission interpreted as odd amplitude/even phase; this is differentiated from glottal source characteristics: even amplitude/odd phase. This motivates a DTLTI system
