SPEECH DATA PROCESSING IN REAL TIME

Abstract

The processor is a high-speed, special-purpose transistorized digital computer which uses as an input the voice signals derived from an 18-channel vocoder and a quantizing and normalizing multiplex. Through the use of a magnetic drum and associated circuitry for temporary storage, arithmetic operations, counting, comparing, etc., the system is capable of selecting the voice frequency-spectrum pattern in storage which is the best acceptable approximation to the unprocessed pattern and subsequently of the accumulation of statistics on the input speech sample. Although the processor is unique in its entirety, most of the logic of which it is comprised was implemented by quite conventional methods. There is one set of logic which is unique and sufficiently sophisticated to be of consi erable interest. This is the set of logic which detects the best acceptable spectrum pattern approximations in real time. (Author)
