SAN FRANCISCO ­— iPhone 4S users fed up with Siri still haven’t made a specific enough case that Apple Inc. over-hyped the capabilities of its voice-recognition software, the company’s lawyers contend in a motion to dismiss filed Tuesday.

“Plaintiffs’ new claim is that Apple represented that Siri would always work perfectly, ‘without a single hiccup,’ and would never fail to provide ‘adequate response(s)’ to any and all questions and commands,” wrote Apple attorney Gail Lees, a Gibson, Dunn & Crutcher partner. “But Apple never made any such representation.”
