US Patent 11232431 Transaction management based on audio of a transaction

An example transaction analysis platform is described herein. The transaction analysis platform may analyze an audio signal to determine whether a user is associated with a transaction. The transaction analysis platform may determine that a tone of the audio signal is a transaction tone associated with the transaction. The transaction analysis platform may process, based on detecting the transaction tone, the audio signal to identify a set of tones associated with the transaction. The transaction analysis platform may generate, based on a quantity of the set of tones, transaction information associated with the transaction, wherein the transaction information identifies a quantity of items associated with the transaction, wherein the quantity of items corresponds to the quantity of the set of tones. The transaction analysis platform may perform an action associated with the transaction information and a transaction account of the user.
