Ignatius G. Mattingly (1927–2004) was a prominent American linguist and speech scientist.
[1] Prior to his academic career, he was an analyst for the National Security Agency from 1955 to 1966.
[2] He was a Lecturer and then Professor of Linguistics at the University of Connecticut from 1966 to 1996 and a researcher at Haskins Laboratories from 1966 until his death in 2004.
Shearme,[6] adapted the Haskins Pattern playback rules to write the first computer program for synthesizing continuous speech from a phonetically spelled input.
A further step toward a reading machine for the blind combined Mattingly's program with an automatic look-up procedure for converting alphabetic text into strings of phonetic symbols.
