LAS VEGAS -- Yahoo Inc. unveiled Yahoo oneSearch 2.0, a new version of its mobile search service that will now let users initiate searches faster using text or voice.

The online company also intends to provide greater relevance through more detailed search results by opening Yahoo oneSearch to publishers. Publishers will be allowed to integrate content, simplify search input and voice-enabled search, and make search instantly accessible on the idle screen of many phones.

"With the launch of Yahoo oneSearch in 2007, we revolutionized mobile search by re-creating search specifically for the mobile phone, focusing on answers, not just Web links," said Marco Boerries, executive vice president of Connected Life at Yahoo. "With Yahoo oneSearch 2.0, we are fundamentally changing the way consumers use the Internet on their mobile phones.

"Yahoo's strategy behind opening oneSearch and enabling publishers to integrate relevant content into oneSearch results is to make it more likely that consumers will be able to find exactly what they're looking for," he said.

For example, when searching for "Italian restaurants," users get information such as addresses and phone numbers.

Open results could include information from restaurant booking companies displaying the number of available reservations.

In his keynote address today at the CTIA Wireless 2008 conference, Mr. Boerries said that Yahoo plans to foster the mobile ecosystem and extend its leadership in mobile.

This was no surprise to attendees, as the Internet giant has spent the past three years aggressively rolling out offerings targeted at addressing key needs of the mobile ecosystem.

Yahoo's mobile homepage, oneSearch, oneSearch 2.0, oneConnect and onePlace are some examples of Yahoo's recent mobile initiatives.

"We all agree that the mobile Internet opportunity is massive," Mr. Boerries told the audience. "The key question is how to enable the supporting mobile ecosystem in order to realize its full potential.

"With Yahoo's technical expertise, monetization experience and strength in developing innovative popular consumer services, we believe we are extremely well-positioned to be a positive driving force," he said. "We are playing an increasingly essential role in helping the ecosystem's constituents overcome some of the biggest challenges that have limited its growth to date."
