A technology platform for the delivery of dynamic, interactive audio advertisements which may be played in response to a consumer initiated request for information via a telephone. More specifically, the invention provides advertising supported information services that are related to a keyword specified in the consumer initiated request. In one specific embodiment, at a customer station, a consumer is connected to a call processing system. The call processing system then receives a request for information from the consumer. To determine a response, the request is examined for the presence of one or more keywords that are not necessarily associated with telephone directory assistance and/or business categories as assigned by a telephone service or other directory provider. The keyword is then used to determine a subject matter area associated with the request, and an advertisement categorized within the associated subject matter area is identified.
