Ignatius Mattingly , working with British collaborators, John N. Holmes  and J.N. Shearme , 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. In the 1960s he also produced the first prosodic synthesis by rule.
