Raimo Olavi Toivonen

The development of speech synthesis began in 1975 at TUT; in 1976, it was moved to the VTT Technical Research Centre of Finland in Tampere, and again to the TUT electronics department in 1978, where it remained until 1981. Toivonen joined in January 1977.[10][11][12][9][8][1]

The first presentation of the Intelligent Speech Analyser (ISA) (by Toivonen) took place in January 1987 at the Finnish Phonetics Meeting at Jyväskylä University.[4] Work started in 1985 and has continued since then.[2][3]

In 100 academic theses, 27 of which are academic dissertations, spoken languages have been studied with the help of the ISA developed by Toivonen. There are a total of almost 500 publications. Using ISA, 14 spoken or written languages have been researched. These are Finnish, Swedish, Estonian, Icelandic, Hungarian, Polish, Czech, German, Russian, English, French, Greek, Portuguese and Spanish.[2][3][5][6][7][16][17][18][19][20]
