I remember having a discussion on this voice synthesis research with two engineers from Lannion France-Telecoms laboratories in a colloquium in Liège (University) in the late 1980s. They explain their technique of “diphone” and I suggested that they should consider it as a concept that could completely transform phonology since instead of articulating one sound onto another sound, they articulated a diphone onto another diphone, a diphone being the final half of a phoneme articulated onto the first half of another phoneme. Thus they articulated diphone /c-a/ (last half of /c/ and first half of /a/) onto the diphone /a-t/ (last half of /a/ and first half of /t/) and then on the diphone /t-i:/ (last half of /t/ and first half of /i:/, the first phoneme of “eats”) to produce the sequence “cat ea[ts]”. This is a major revolution in phonology since in the diphone the articulating point between the two phonemes is itself integrated. Long before the Voxygen existed and long before France Telecoms due to later become Orange were privatized by Jospin in 1999 when they opposed setting portable telephones at the center of negotiations with China and Japan on the new standard of portable telephones that have produced our present 3G and 4G and 5G telephone systems. I remember discussing “Simone”, the SNCF synthetic voice announcer, with the night station master in Vichy one Thursday night when waiting for the night train to Paris due at 2 o’clock and a few minutes a.m. in 1998. I am talking about what was done and made public at least more than twenty years before Voxygen.
