Abstract
While it has been suggested that the speech transmission index (STI) for on environment may be calculated using speech rather than test signals, computational artifacts distort the speech analyses whereas they have minimal impact on analyses with test signals. This report documents some of the difficulties encountered when using speech as the probe stimulus and proposes modifications in STI computations to circumvent some of the problems
