If you don't like Paul Moyer and Colleen Williams together, just replace Paul with Sharon Tay. Don't worry. You won't have to listen to Sharon speak with Paul's voice — you can use her real voice. Want to make the newscast really interesting? Have Sharon speak Mandarin as a complete contrast to Colleen's English.
Not outrageous enough? What if you replace all of the talking heads with a kangaroo (sports), ostrich (weather), wombat (anchor) and koala (field reporter) and have each of them speak one of four different Aussie accents. Now that's a crazy personalized newscast.
If IBM has anything to say about it, you might just have this chance. Last week IBM filed a patent application (20060136226) for a "system and method for creating artificial TV news programs." Their abstract is nicely written; so I'll just include it here:
The present invention relates to interactive television, in particular to a method and system for creating artificial TV programs according to TV viewers' preferences and more particularly to a system and method for enabling a TV viewer to replace the newscaster of a TV news program by an artificial newscaster and to translate the newscaster's speech into the language of his choice. The present invention combines automatic speech recognition (Speech-To-Text processing), automatic machine translation, and audio-visual Text-To-Speech (TTS) synthesis techniques for automatically personalizing TV news programs.
