WebThe theoretical model proposed by Hongisto relates the decreased performance (DP) to the Speech Transmission Index (STI). The model predicts that for STI values from 0.7 to 1, which correspond to a speech signal with an intelligibility of almost 100%, the DP remains constant at 7%, but few studies have examined the high end of this range. WebSpeech Transmission Index STI is the most acknowledged standardized parameter for assessing the intelligibility of a spoken message.
