摘要： The specification and drawings present a new method, apparatus and software product for listening assistance to a user of a phone terminal with a headset or a hearing aid for selective listening of a local acoustic source in a noisy environment by said user utilizing a combination of said phone terminal and said headset. The method for the listening assistance comprises of placing the phone terminal near a desired local acoustic source, switching a mode of the phone terminal to a listening mode, providing to the headset or to the hearing aid a signal (e.g., a wireless signal) generated by the phone terminal in response to an acoustic signal from the local acoustic source, and providing to the user an output acoustic signal generated by the headset or by the hearing aid in response to that signal thus providing said listening assistance to the user.

摘要： A method and system for tracking human speakers using a plurality of acoustic sensors arranged in an array to detect the voice of the speakers within an angular range in order to determine a most favorable direction for detecting the voice in a detection period. A beamformer is used to form a plurality of beams each covering a different direction within the angular range and generate a signal responsive to the voice of the speakers for each beam. A comparator is used to periodically compare the power level of the signal of different beams in order to determine the most favorable detection direction according to the movement of the human speakers. A voice activity detection device is used to indicate to the comparator when the voice of the speakers is detected so that the comparator determines the most favorable detection direction based on the voice of the speakers and not the noise when the speakers are silent during the detection period.

摘要： Method and apparatus for enhancing a coded audio signal comprising indices which represent audio signal parameters which comprise at least a first parameter representing a first characteristic of speech are disclosed. A current first parameter value is determined from an index corresponding to at least the first parameter. The current first parameter value is adjusted in order to achieve an enhanced first characteristic, thereby obtaining an enhanced first parameter value. A new index value is determined from a table relating index values to at least first parameter values, such that a new first parameter value corresponding to the new index value substantially matches the enhanced first parameter value.
