A text-to-speech synthesis system receives digital code representative of characters from a local or remote source, and converts those character codes into speech. A set of allophone rules is contained in a memory and each incoming character set is matched with the proper character set to describe the sound of that particular character set. A microcontroller is dedicated to the comparison procedure which provides allophonic code when a match is made. The allophonic code is provided to a speech producing system which has a system microcontroller for controlling the retrieval, from a read-only memory, of digital signals representative of the individual allophone parameters. The addresses at which such allophone parameters are located are directly related to the allophonic code. A dedicated microcontroller concatenates the digital signals representative of the allophone parameters, including code indicating stress and intonation patterns for the allophones. An LPC speech synthesizer receives the digital signals and provides analog signals corresponding thereto to a loud speaker to produce speech-like sounds with stress and intonation.
