Colin Champion has worked in speech research since 1997. He has been involved in the SRbS project since the idea took shape at the beginning of 2010, and currently manages the project. His technical involvement also began before the project took concrete form with an investigation into various ideas for applying Continuous State HMMs to the speech signal. He wrote a series of three internal papers on the subject under the title "Recognition by Rule" of which the first two were false starts; the third, written in the latter part of 2011, is available from the project document library. He also has a long-standing interest in formant tracking.
In private life he is a timid but dedicated mountain biker, and has ridden the high passes of the Himalayas and the Andes. He and his wife are believed to be the first westerners to have cycled the Se La in Arunachal Pradesh. He reads books in Italian, having previously read in French and before that in English.
