    摘要: A system generates an audio signature for a data item based on a source identifier associated with the data item. The system receives a source identifier along with a data item and maps the source identifier to the audio signature using a mapping function that allows a user to distinguish the audio signature from other audio signatures generated for other sources. The mapping functions always map the same source identifier to the same audio signature. The system outputs the audio signature to a user. This enables the user to associate the audio signature with the source. The data item can include, an electronic mail message, a pager signal, a telephone call, a data item in an instant messaging system, an indicator of an entry of a new participant into a conference call or a chat room, or an electronic cookie that identifies a client computer system to a web site.
