TLDR
In this article, a composite filter with parallel filters in cascade is proposed to synthesize speech and music phonation formed by spectral formants, and the composite filter is implemented with mutually adjacent formants in cascade filter elements.Abstract:
Speech and music phonation formed by spectral formants is synthesized by a composite filter containing parallel filters in cascade. The composite filter design is generated by partial-function expansion of the approximate sound channel transfer function ##EQU1## and the composite filter is implemented with mutually adjacent formants in cascade filter elements.read more

Cascade/parallel terminal analog speech synthesizer and a strategy for consonant—vowel synthesis
TL;DR: The FORTRAN subroutine as discussed by the authors was developed for the synthesis of speech and speech-like waveforms appropriate for psychophysical experimentation, and it can be configured in cascade and/or in parallel by changing the value of the logical switch.

Programmable synthesis using a new "Speech microprocessor"
TL;DR: Two NMOS LSI devices which implement a programmable "speech microprocessor" have been developed, orienting the architecture toward common features of several classes of digital vocal tract models, so synthesis computations involving a large number of multiplies, adds, and other operations can be performed efficiently.
