TLDR
In this paper, a system for voice signal processing including recognizing input voice messages and generating output voice messages is described, including an audionic clock, a calculator, and an announciator.Abstract:
A system is provided for voice signal processing including recognizing input voice messages and generating output voice messages. Digital processing of voice signals yields particular advantages. Voice responsive operations provide operator interaction flexibility. Communication of digital information in response to voice information provides data compression for communication applications. Other applications of the voice signal processing system include an audionic clock, an audionic calculator, and an audionic announciator.read more

Speech synthesis by concatenation of formant encoded words
TL;DR: The speech produced by most audio response units is noticeably artifical and mechanical sounding as discussed by the authors, which makes it difficult to distinguish between real speech and synthesized speech. But the response units can select speech sounds, stored in analog or coded digital form, as the excitation for a speech synthesizer, for example in telephone audio announcement terminals.
