Résumé

The intelligibility of speech in noise is a good example of the detection of a real signal. The presence of an echo of the original signal or direct sound (by analogy with room acoustics) has an obvious interest, because an early echo increases intelligibility, while a delayed echo deteriorates it. Recent works have shown that the auditory integration of an echo with a short delay is not complete in the presence of noise. Those measurements were performed using intelligibility scores. We have measured the Speech Reception Threshold (SRP) corresponding to a given intelligibility score for various phonetic transitions and various delays. The results show irregular variations of the SRP according to the delay and phonetic transitions.
