ABSTRACT:
The invention relates to a voice processing system capable of outputting voice prompts and background music. The volume of background music is progressively variable relative to the voice prompts or speech. The progressive variation is effected by multiplying the background music samples by a scaling factor and then adding together a current voice sample and the scaled background music sample. Accordingly, when the combined samples are output to the user the volume of the background music varies.
