Abstract (en)

The present invention concerns a method and an assembly designed to enhance the intelligibility of speech produced by a sound device in a noisy environment. The assembly comprises a microphone, or a telecommunication unit, which provides to a data processing module the voice of a remote speech. The data processing module is designed to combine specific algorithms offering a perceptual improvement of the produced speech by increasing intelligibility, by saving an adequate signal quality and by saving as far as possible the overall power consumption. The enhanced speech as produced by the data processing module is then played in a speaker.
