    摘要: An audio privacy system reduces the intelligibility of speech in an audio signal while preserving prosodic information, such as pitch, relative energy and intonation so that a listener has the ability to recognize environmental sounds but not the speech itself. An audio signal is processed to separate non-vocalic information, such as pitch and relative energy of speech, from vocalic regions, after which syllables are identified within the vocalic regions. Representations of the vocalic regions are computed to produce a vocal tract transfer function and an excitation. The vocal tract transfer function for each syllable is then replaced with the vocal tract transfer function from another prerecorded vocalic sound. In one aspect, the identity of the replacement vocalic sound is independent of the identity of the syllable being replaced. A modified audio signal is then synthesized with the original prosodic information and the modified vocal tract transfer function to produce unintelligible speech that preserves the pitch and energy of the speech as well as environmental sounds.

    摘要: A method of generating a bid for an advertiser for placement of an advertisement in association with a search results list, where the search results list is generated in response to a search query, is provided. In one embodiment, the method includes: a) associating the at least one keyword with the bid, wherein the search query is associated with the at least one keyword, and b) determining an amount of the bid, associated with the at least one keyword, for placement of the advertisement in association with the search results list generated in response to the search query associated with the at least one keyword. The bid is determined based at least in part on bids by other advertisers in competition with the first advertiser for placement of other advertisements with an expectation that the determined bid may elicit a desired change in the bids by the other advertisers.

    摘要: A server-based method of automatically generating a plurality of bids for an advertiser for placement of at least one advertisement in association with a search results list is provided. The method includes: a) receiving at least one candidate advertisement, b) creating a list of candidate keywords, c) estimating a click-through rate for each advertisement-keyword pair, d) calculating a return on advertising investment (ROAI) for each advertisement-keyword pair, and e) calculating a bid amount for each advertisement-keyword pair. In another aspect, a server-based method of generating a bid for placement of an advertisement in association with a search results list is provided. In other aspects, a method of selecting one or more keywords in conjunction with the bid is provided as well as a method of determining a return on advertising investment (ROAI) information for an advertiser in conjunction with the bid is provided.
