Abstract
A system and method for measuring speech quality of a mobile telephone device in the presence of noise is provided. In one embodiment the method may comprise determining a test speech volume, which that comprises the speech volume that results in the best speech quality provided by the telephone device when the telephone device is not in the presence of noise. Subsequently, the method may include audibly producing test speech having a volume substantially equal to the test speech volume for reception by the telephone device, concurrently with audibly producing test speech, supplying audible noise to the telephone device, receiving a signal that includes the test speech and noise communicated from the telephone device; and determining a speech quality for the received signal. The method may be repeated for numerous telephone devices, including handsets and telephone accessory devices, under different noise conditions, and/or for different communication networks.
