A computer device (100) for processing audio signals is described. The computer device (100) includes at least a processor and a memory. The computer device (100) is configured to receive a bitstream comprising a combined audio signal, the combined audio signal comprising a first audio signal including speech and a second audio signal. The computer device (100) is configured to compress the combined audio signal to provide a compressed audio signal. The computer device (100) is configured to control a dynamic range of the compressed audio signal to provide an output audio signal. In this way, a quality of the speech included in the output audio signal is improved.

Speech conveyed over a network, such as during an electronic conference may be more difficult to understand if the recipient has difficulty understanding the speech of users having a particular speech attribute. However, other recipients may have no difficulty understanding the speech. As provided herein, speech provided by a user may have phonemes comprising accents or other speech pattern that, if removed, are more readily understood by a particular user. Such alterations are provided only to the users that require it, such as by a server or a specific user's communication device, without affecting the speech concurrently presented to other users.
