Abstract
There is provided a method of generating a signal representing the speech of a user, the method comprising obtaining a first audio signal representing the speech of the user using a sensor in contact with the user; obtaining a second audio signal using an air conduction sensor, the second audio signal representing the speech of the user and including noise from the environment around the user; detecting periods of speech in the first audio signal; applying a speech enhancement algorithm to the second audio signal to reduce the noise in the second audio signal, the speech enhancement algorithm using the detected periods of speech in the first audio signal; equalizing the first audio signal using the noise-reduced second audio signal to produce an output audio signal representing the speech of the user.
