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.
Claims11
A method for processing background music samples within a voice processing system connectable to a communication network, comprising the steps of:
- providing a plurality of digital background music samples,
- applying digital volume scaling factors to the background music samples, wherein the digital volume scaling factors progressively vary from a first level to a second level, and
- outputting the scaled background music samples for transmission over the communication network.
