Abstract The effect of masking due to fluctuating sources on speech intelligibility is a phenomenon difficult to predict. Intelligibility scores vary with the efficiency of the energetic masking while the linguistic content of the message and listener!'¯s cognitive performances add to the general incertitude that peaks for the case of masking speech. The present contribution proposes a signal-based assessment of the energetic masking at the sentence level. A mapping onto the scale of the speech intelligibility index is established for stationary noise. Predictions are quantitatively compared with the results of an intelligibility test for speech-modulated noise. The model is independent of voices similarities and semantic features, two important sources of informational masking.
