Originally at the initiative of a leading medical voice faculty, Ternström
has written voice/sound analysis software for PC’s, which has become a prime tool, not only at this department
but in many other places around the world. Together with Lennart Neovius from the speech group, he has also created
an innovative software tool for interactive real-time signal processing. Both of these packages are commercially
available from Hitech Development AB in Sundbyberg, for which Ternström acts as scientific advisor.
