Abstract:
Provided are methods and systems for improving the intelligibility of speech in a noisy environment. A communication model is developed that includes noise inherent in the message production and message interpretation processes, and considers that these noises have fixed signal-to-noise ratios. The communication model forms the basis of an algorithm designed to optimize the intelligibility of speech in a noisy environment. The intelligibility optimization algorithm only does something (e.g., manipulates the audio signal) when needed, and thus if no noise is present the algorithm does not alter or otherwise interfere with the audio signals, thereby preventing any speech distortion. The algorithm is also very fast and efficient in comparison to most existing approaches for speech intelligibility enhancement, and therefore the algorithm lends itself to easy implementation in an appropriate device (e.g., cellular phone or smartphone).

Claim (Index 9):
A system for enhancing intelligibility of speech, the system comprising:\n at least one processor; and\n a computer-readable medium coupled to the at least one processor having instructions stored thereon which, when executed by the at least one processor, causes the at least one processor to: \n receive from a far-end of a communication channel a transmitted audio signal containing speech produced by a first user at the far-end of a communication channel for playout to a second user at a near-end of the communication channel; \n determine 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; \n modify the received audio signal based on the one or more determined parameters; and \n provide the modified audio signal to a loudspeaker at the near-end of the communication channel for playout to the second user, \n wherein each of the production signal-to-noise ratio and the interpretation signal-to-noise ratio are estimated in a plurality of frequency bands, \n wherein determining the one or more parameters for enhancing the intelligibility of the speech contained in the received audio signal includes generating a statistic that includes an estimate of mutual information, in each of the plurality of frequency bands, between an intended version of the transmitted audio signal and an interpreted version of the received audio signal.
