Although Texas Instruments is most commonly associated with early speech synthesizers, The Telesensory Systems S14001A was introduced in late 1975, making it the first of such devices. TSI was developing the Speech+, a talking calculator for visually impaired users, and collaborated with Silicon Systems, Inc. to manufacture a speech synthesizer based on the original speech synthesis algorithm developed by Dr. Forrest S. Mozer. The resulting device was the S14001A, a 1500-transistor PMOS device with a 4-bit D/A converter, which operates at 13KHz.
