What software is the talking cat in the iPhone?

Siri. . . . . siri (Apple Intelligent Voice Assistant)

Edit

Siri is a voice control function applied by Apple on its product iPhone 4S. Siri can turn iPhone 4S into an intelligent robot. Using Siri, users can read text messages, introduce restaurants, ask about the weather, set alarm clocks by voice, etc. through their mobile phones. Siri can support natural language input, and can call the system's own weather forecast, schedule, search information and other applications. It can also continuously learn new voices and intonations and provide conversational responses. However, in October 2012, SIRI was exposed to be suspected of "pornography" and caused controversy, which has now been resolved.
