Claim One:
1. A computer-implemented method for enhancing intelligibility of speech, the method comprising: receiving a transmitted audio signal containing speech produced by a first user at a far-end of a communication channel for playout to a second user at a near-end of the communication channel; determining one or more parameters for enhancing intelligibility of the speech contained in the received audio signal based on estimates of production noise of the transmitted signal and interpretation noise of the received signal; modifying the received audio signal based on the one or more determined parameters; and providing the modified audio signal to a loudspeaker at the near-end of the communication channel for playout to the second user, wherein each of the production signal-to-noise ratio and the interpretation signal-to-noise ratio are constant with respect to time, wherein determining the one or more parameters for enhancing the intelligibility of the speech contained in the received audio signal includes generating (i) a first correlation coefficient between the transmitted signal and the production noise and (ii) a second correlation coefficient between the received signal and the interpretation noise, each of the first correlation coefficient and the second correlation coefficient being constant with respect to time.
