BACKGROUND OF THE INVENTION

1. Field

This invention relates generally to telecommunications, and more specifically to a system and a method for delivering audio announcement.

2. Related Art

There are many existing methods for delivering audio announcement to a user. In one scenario, a person dials a telephone number at a telephone to connect to a machine and listens to a pre-recorded announcement such as location and business hours of a merchant, road conditions or weather conditions. The machine, from a simple answering machine to a sophisticated Interactive Voice Recorder (IVR), delivers the announcement by sending the audio signals of the announcement to the telephone over a telephony network. For the user to listen to the announcement again, he/she has to dial the telephone number to connect to the machine again. When there is an update for the announcement, an operator records a new announcement in the machine. The user needs to dial in to listen to the announcement.

In a different scenario, a radio broadcasting system delivers an announcement such as world and local news, weather reports, sports updates, and financial news by sending audio signals of the announcement to a radio. To deliver an announcement, a broadcaster reads the announcement or plays a pre-recorded announcement through the radio broadcasting system. To deliver an announcement multiple times, the broadcaster reads or plays the announcement multiple times. When there is an update for an announcement, the broadcaster reads the updated announcement or plays a pre-recorded updated announcement. To deliver a plurality of announcements, a broadcaster repeats the above process for each announcement, whether it is a repeat announcement, an updated announcement, or a new announcement. The broadcaster typically delivers the announcements infrequently or at a mixed time, such as every hour by the hour, 6 times a day, or in the morning and evening hours.

In another scenario, a television broadcasting system delivers an announcement in a similar fashion as a radio broadcasting system.

With the emergence of the Internet, a person uses a Web browser to obtain information, including listening to an announcement over the Internet. To listen to an announcement, a person navigates a web page or multiple web pages, and selects a textual or graphical representation of the announcement. Where there is an update for the announcement, the person needs to navigate a web page or multiple web pages, and selects a textual or graphical presentation of the announcement to listen to the announcement.

The above scenarios illustrate deficiencies in delivering audio announcement to a user in an effectively and timely manner. Therefore, there is a need to improve the effectiveness and timeliness of delivering audio announcement.

BRIEF SUMMARY OF THE INVENTION

A method for delivering audio announcements includes: receiving an announcement package, the announcement package including a package identity, a package update time, and one or more announcement items; and presenting the announcement package to an audio player. Each announcement item includes an item identity, and a summary part, where the summary part includes audio information. The audio information includes an audio data type and audio data. Updates for the announcement package can be received, where the announcement package is modified according to the update. A content of the announcement package can be replaced, deleted, or added. The announcement item can be presented to the audio player once, repeatedly, or periodically. In this manner, audio announcements are delivered in an effective and timely manner.

Announcer 250 modifies package update time 202 by replacing the content of package update time 202 with the content of package update time 222.

Announcer 250 modifies prelude 203 by replacing the content of prelude 203 with the content of prelude 223.

Announcer 250 matches the item identity of announcement item 225 with the item identity of announcement items 205 and 206. Announcer 250 determines that the item identity of announcement item 225 â€œSportsUpdate 10324â€ matches the item identity of announcement item 205 â€œSportsUpdate 10324â€ . Announcer 250 replaces the content of announcement item 205 with the content of announcement item 225.

Announcer 250 matches the item identity of announcement item 226 with the item identity of announcement items 205 and 206. Announcer 250 determines that the item identity of the announcement item 226 â€œNews-Item-253â€ does not match the item identity of announcement items 205 and 206. Announcer 250 adds announcement item 226 to announcement package 200.

After the update, announcement package 200 becomes,
