摘要： The invention relates to a method of identifying and correcting errors in a noisy binary mask. An object of the present invention is to provide a scheme for improving a binary mask representing speech. The problem is solved in that the method comprises a) providing a noisy binary mask comprising a binary representation of the power density of an acoustic signal comprising a target signal and a noise signal at a predefined number of discrete frequencies and a number of discrete time instances; b) providing a statistical model of a clean binary mask representing the power density of the target signal; and c) using the statistical model to detect and correct errors in the noisy binary mask. This has the advantage of providing an alternative and relatively simple way of improving an estimate of a binary mask representing a speech signal. The invention may e.g. be used for speech processing, e.g. in a hearing instrument.

摘要： An audio processing device includes a) an input unit for converting a time domain input signal to a number NI of input frequency bands and b) an output unit for converting a number NO of output frequency bands to a time domain output signal. A signal processing unit processes the input signal in a number NP of processing channels, smaller than the number NI of input frequency bands. A frequency band allocation unit allocates input frequency bands to processing channels. A frequency band redistribution unit redistributes processing channels to output frequency bands, and a control unit dynamically controls the allocation of input frequency bands to processing channels and the redistribution of processing channels to output frequency bands.
