摘要： A listening device includes an ear-part for being worn in or at an ear of a user, a microphone system including at least two microphones each converting an input sound to an electrical microphone signal, and a TF-conversion unit for providing a time-frequency representation of the at least two microphone signals. Each signal representation includes complex or real values of the signal in a particular time-frequency unit. The listening device also includes a DIR-unit with a directionality system providing a weighted sum of the at least two electrical microphone signals thereby providing at least two directional microphone signals having maximum sensitivity in spatially different directions and a combined microphone signal. Each time-frequency unit of the combined signal is attributable to a particular direction. A frequency shaping-unit modifies one or more selected time-frequency units to indicate directional cues of input sounds providing an improved directional output signal.

摘要： The invention relates to a method of automatic sound recognition. The object of the present invention is to provide an alternative scheme for automatically recognizing sounds, e.g. human speech. The problem is solved by providing a training database comprising a number of models, each model representing a sound element in the form of a binary mask comprising binary time frequency (TF) units which indicate the energetic areas in time and frequency of the sound element in question, or of characteristic features or statistics extracted from the binary mask; providing an input signal comprising an input sound element; estimating the input sound element based on the models of the training database to provide an output sound element. The method has the advantage of being relatively simple and adaptable to the application in question. The invention may e.g. be used in devices comprising automatic sound recognition, e.g. for sound, e.g. voice control of a device, or in listening devices, e.g. hearing aids, for improving speech perception.

摘要： A method and device reduce artifacts in an audio processing algorithm for applying a time and frequency dependent gain to an input audio signal. The method provides a time frequency representation of an input audio signal comprising a number of frequency bands; applies an audio processing algorithm providing an estimated algorithm output signal; determines for each frequency band a difference between a value of the estimated gain signal at a given time and at a preceding time; averages the difference over a predefined time; provides a confidence estimate based on the time averaged difference, the said confidence estimate being relatively low in case said time averaged difference is above a predetermined threshold level and relatively high in case said time averaged difference is below a predetermined threshold level; and optionally applies the confidence estimate to the noise reduced output signal thereby providing an improved algorithm output signal.
