Systems and methods are provided for facilitating media playback in online auctions. A method may include detecting an indication of an auction event associated with an online vehicle auction for a first vehicle. The method may also include determining current auction information associated with the online vehicle auction. The method may further include determining auction event information associated with the auction event. Additionally, the method may include identifying, based at least in part on the current auction information and the auction event information, one or more media files for playback on a bidder device. The method may also include transmitting, to the bidder device in response to the indication of the auction event, the one or more media files for playback on the bidder device according to a determined sequence, which may result in acoustic output of one or more auctioneer phrases.
