11. A method to use a system using a user device in communication with a stored data repository, that reduces the background noise from a speech audio signal generated by a user, comprising: receiving a speech audio signal with a user device, said user device further comprises a processor and a memory; and providing a noise reduction device, in communication with a stored data repository, and in communication with said user device, is configured to: convert said received speech audio signal to text; generate synthetic speech based on a speech data corpus or speech model data of the user stored in said stored data repository and said converted text; determine the predicted subjective quality of the received speech audio signal if that signal were to be transmitted to a far end listener; determine the predicted subjective quality of said synthetic speech; and transmit, selectively, said speech audio signal or said synthetic speech, whichever has higher predicted quality based on a comparison between the value of objective quality metrics computed for the speech audio signal and the synthetic speech signal.
