She's a willowy 5 feet 7 and 120 pounds. She'll chat with you endlessly about your interests. And she'll have sex whenever you please -- as long as her battery doesn't run out.

Meet Roxxxy, who may be the world's most sophisticated talking female sex robot. For $7,000, she's all yours.

"She doesn't vacuum or cook, but she does almost everything else," said her inventor, Douglas Hines, who unveiled Roxxxy last month at the Adult Entertainment Expo in Las Vegas, Nevada.

Lifelike dolls, artificial sex organs and sex-chat phone lines have been keeping the lonely company for decades. But Roxxxy takes virtual companionship to a new level.

Powered by a computer under her soft silicone "skin," she employs voice-recognition and speech-synthesis software to answer questions and carry on conversations. She even comes loaded with five distinct "personalities," from Frigid Farrah to Wild Wendy, that can be programmed to suit customers' preferences.

"There's a tremendous need for this kind of product," said Hines, a computer scientist and former Bell Labs engineer.

Roxxxy won't be available for delivery for several months, but Hines is taking pre-orders through his Web site, TrueCompanion.com, where thousands of men have signed up.

"They're like, 'I can't wait to meet her,' " Hines said. "It's almost like the anticipation of a first date."

Women have inquired about ordering a sex robot, too. Hines says a female sex therapist even contacted him about buying one for her patients.

Roxxxy has been like catnip to talk-show hosts since her debut at AEE, the largest porn-industry convention in the country. In a recent monologue, Jay Leno expressed amazement that a sex robot could carry on lifelike conversations and express realistic emotions.

"Luckily, guys," he joked, "there's a button that turns that off."

Curious conventioneers packed Hines' AEE booth last month in Las Vegas, asking questions and stroking Roxxxy's skin as she sat on a couch in a black negligee.

"Roxxxy generated a lot of buzz at AEE," said Grace Lee, spokeswoman for the porn-industry convention. "The prevailing sentiment of everyone I talked to about Roxxxy is 'version 1.0,' but people were fascinated by the concept, and it caused them to rethink the possibilities of 'sex toys.' "
