Abstract
Several measurement techniques exist to quantify the intelligibility of a speech transmission chain. In the objective domain, the Articulation Index [1] and the Speech Transmission Index STI [2], [3], [4], [5] have been standardized for predicting intelligibility. The STI uses a signal that contains spectro-temporal characteristics similar to natural speech. By comparing intensity fluctuations of degraded and reference signals, the modulation transfer function of the system under test is measured from which the STI can then be calculated. In modern speech transmission, various types of coding are used that may behave differently for speech than for the STI test signal, implying a possible incorrect intelligibility prediction. A more fundamental approach in assessing intelligibility is to take natural speech signals, and derive internal representations of the reference and degraded signals, the difference of which can then be used to estimate speech intelligibility.
