ABSTRACT:
A method and apparatus for reducing noise in a speech signal. A handset or remote unit provides to users with a hearing deficiency, a first mode of operation where noise suppressant/speech enhancement algorithms are used during any auditory-related service. There is also provided, in a related mode of operation, speech filtering for reducing noise in a speech signal received through the microphone and outputting the filtered sound to the speaker. The handset includes a microphone for receiving an auditory sound, a receiver for receiving an auditory signal and a speech filter for suppressing noise in the auditory signal and sound. The speech filter also may be configured to shift the frequency and/or alter the intensity of the auditory signal and sound. The speaker is used for amplifying and outputting the enhanced speech component as an audible sound.
