Abstract
A voice controlled assistant has two speakers to produce high quality stereo sound. The voice controlled assistant generates a first frequency portion and a second frequency portion used to produce stereo sound. The frequency portion is filtered to remove a range of frequencies, such as the low frequency range. The second frequency portion, together with the frequency portion removed from the first frequency portion, are output as sound.
