One-chip LSI speech synthesizer

摘要

There is disclosed a one-chip speech synthesizer capable of providing synthesized human voices through a new and effective concept of LSI architecture. The synthesizer may execute all of the steps necessary for processing of sample data and enhances the processing speed through a new memory architecture by constructing the one-word length of a control memory (control ROM) longer than the one-word length of a data memory (data ROM). The synthesizer reproduces audible synthesized sounds merely by an added amplifier outside the one-chip LSI semiconductor device without the need to provide a digital-to-analog converter. The LSI device may be used with an expandable external memory as an extension of the data memory (data ROM) whenever a large number of words are to be processed.
