No Surprise, Siri Satisfies

More than half of U.S. users of Apple's iPhone 4S are "very satisfied" with the Siri voice-command feature, according to consumer research from international research firm Parks Associates.

The survey finds an additional 21 percent are "satisfied," leaving just a small number of dissatisfied users.

Thirty-seven percent of iPhone 4S owners would want a similar voice-command interface for their TV sets, while roughly 20 percent would not.

"Siri is clearly a hit among the initial iPhone user base," said John Barrett, director of consumer analytics at Parks Associates, in a statement. "Consumers like Siri because it's convenient, easy to use, and helpful for remembering important information [e.g., birthdays], and its hands-free capability makes it easy to send texts, email, and phone calls."

Apple could soon be launching a TV set with a Siri voice interface. The popularity and usability of the company's natural-language user interface could determine the extent of Apple's impact on the TV market.

"People are expressing some reservations about Siri that could impact its popularity on other platforms," Barrett said. "Some said Siri didn't work well against background noise. Others said it had trouble understanding commands. These problems could be amplified in a noisy living room, where the main TV would be located."
