Abstract

A method and apparatus that filters audio data received from a speaking person that includes a specific filter for that speaker. The audio characteristics of the speaker's voice may be collected and the specific filter may be formed to reduce noise while also enhancing voice quality. For instance, if a speaker's voice does not contain specific frequencies, then a filter may cancel the noise at such frequencies to ease noise cancellation and reduce processing sound spectrum for cleaning that is not needed. Additionally, the strength frequencies of a speaker's voice may be identified from the collected audio characteristics and those spectrums can be filtered with finer granularity to provide a speaker specific filter that enhances the voice quality of the speaker's voice data that is transmitted or output by a communication device. The audio data may also be output based upon a user's predefined hearing spectrum.

Description

FIELD OF INVENTION[0001]The present invention relates to communication systems, such as communication systems that utilize cellular phones, mobile computer devices, tablets, laptops, or other terminal devices. More particularly, the present invention relates to a system, method and device configured to edit received audio data to improve voice quality voice data that is received for recording or transmission.BACKGROUND OF THE INVENTION[0002]Telecommunication endpoints are often equipped with a noise reduction device. Such a device is typically configured to filter voice data received by the device to deliver a better voice content when that data is output or transmitted as outputted audio data. However, filters used in such noise reduction mechanisms are typically general purpose filters designed to process audio in a generic manner. As a result, the noise reduction may fail to provide a great improvement in voice quality or other attributes to outputted audio data.[0003]We have det...
