Abstract

The Speech Transmission Index is approaching its 4th decade of existence. While the first measuring device built in the 1970s could barely fit inside a car, inexpensive pocket-size STI measuring solutions are now available to the world. Meanwhile, the STI method has continually evolved in order to deal with an increasing array of measuring challenges. This paper investigates how the STI kept up with these challenges and analyses possible room for further improvement. Also, a roadmap for further development of the STI is proposed.
