Billionaire investor Carl Icahn has taken a 9.27 percent passive stake in speech recognition and digital imaging software maker Nuance Communications.

Icahn, who is known for taking large "activist" positions in companies and pushing for management change, has taken a passive position in Nuance.

Apple uses Nuance's speech recognition technology in its iPhone devices as part of its "Siri" voice recognition feature.
