The application further relates to a method of providing a binaural speech intelligibility prediction value. The system comprises a) first, second, third and fourth input units for providing time-frequency representations x l (k,m), x r (k,m), y l (k,m) and y r (k,m) of said left and right noise-free versions and said left and right noisy and/or processed versions of the target signal, respectively, k being a frequency bin index, k= 1 , 2 , ..., K, and m being a time index; b) a first Equalization-Cancellation stage adapted to receive and relatively time shift and amplitude adjust the left and right noise-free versions x l (k,m) and x r (k,m), respectively, and to provide a resulting noise-free signal x ( k,m ); c) a second Equalization-Cancellation stage adapted to receive and relatively time shift and amplitude adjust the left and right noisy and/or processed versions y l (k,m) and y r (k,m), respectively, and to provide a resulting noisy and/or processed signal y(k,m); and d) a monaural speech intelligibility predictor unit for providing final binaural speech intelligibility predictor value SI measure based on said resulting noise-free signal x(k,m) and said resulting noisy and/or processed signal y(k,m) ; wherein said first and second Equalization-Cancellation stages are adapted to optimize the final binaural speech intelligibility predictor value SI measure to indicate a maximum intelligibility of said noisy and/or processed versions y l , y r of the target signal by said listener. The invention may e.g. be used in development systems for hearing aids.

    • Signal processing methods for predicting the intelligibility of speech, e.g., in the form of an index that correlate highly with the fraction of words that an average listener (amongst a group of listeners with similar hearing profiles) would be able to understand from some speech material are proposed. Specifically, solutions to the problem of predicting the intelligibility of speech signals, which are distorted, e.g., by noise or reverberation, and which might have been passed through some signal processing device, e.g., a hearing aid are described. In summary, the disclosure present solutions to the following problems:
      1. Monaural, non-intrusive intelligibility prediction of noisy/processed speech signals
      2. Binaural, non-intrusive intelligibility prediction of noisy/processed speech signals
      3. Monaural and binaural intelligibility enhancement of noisy speech signals.
