Abstract From the Canadian patent

The serving of advertisements with (e.g. on) audio documents may be improved in a number of ways. For example, a system may (a) accept information defining at least one ad spot associated with at least one instance of an audio document, (b) accept offers to have advertisements served in the ad spot(s) and (c) arbitrate among competing advertisements using at least the offers, to determine at least one advertisement to be served in that ad spot(s). Examples of documents include radio programs live or recorded musical work , with lyrics live or recorded dramatic works with dialog or a monolog live or , recorded talk shows, voice mail segments of an audio conversation, etc.
