| Description | The need to enhance speech signals arises in many situations in which the speech signal originates from a noisy location or is affected by noise over a communication channel. There are a wide variety of scenarios in which it is desired to enhance speech. Voice communication, for instance, over cellular telephone systems typically suffers from background noise present in the car, restaurant, etc. at the transmitting end. Speech enhancement algorithms can therefore be used to improve the quality of speech at the receiving end. That is, they can be used as a preprocessor in speech coding systems employed in cellular phone standards (e.g., [1]). If the cellular phone is equipped with a speech recognition system for voice dialing, then recognition accuracy will likely suffer in the presence of noise. In this case, the noisy speech signal can be preprocessed by a speech enhancement algorithm before being fed to the speech recognizer. In an air-ground communication scenario, speech enhancement techniques are needed to improve quality, and preferably intelligibility, of the pilot's speech that has been corrupted by extremely high levels of cockpit noise. In this, as well as in similar communication systems used by the military, it is more desirable to enhance the intelligibility rather than the quality of speech. In a teleconferencing system, noise sources present in one location will be broadcast to all other locations. The situation is further worsened if the room is reverberant. Enhancing the noisy signal prior to broadcasting it will no doubt improve the performance of the teleconferencing system. Finally, hearing impaired listeners wearing hearing aids (or cochlear implant devices) experience extreme difculty communicating in noisy conditions, and speech enhancement algorithms can be used to somehow preprocess or “clean” the noisy signal before amplication.
