Siri has been a big selling point for Apple"s iPhone 4S. When it was demonstrated for the first time, Siri became an electronic sensation. Voice commands became the big reason for the iPhone 4S sales rocketing, instead of the internal changes allowing for improved performance. Siri could be used for a great deal of different things, and it wasn"t long before it began to be used for comedic effect. With Siri you could have your iPhone call you "Sugar Daddy", or any other title you wanted. You could even set Siri up to insult people if it was being used in a retail display unit, as some pranksters did. This won"t last forever though.
Thanks to a tip from Neowin reader Ari David, it seems that Apple is removing that feature. Any attempts to get Siri to respond in a sexual manner will be given a negative response now as the voice assistant will not reply with a sexual or derogatory statement. This even applies to the aforementioned "Sugar Daddy". When prompted, Siri will refer to you as "Sugar", but not as "Sugar Daddy", for Apple has updated it to recognize the definition of a sugar daddy. Obviously, this makes the iPhone"s voice assistant more suitable for kids to use. Previously, it was open to abuse from others who may have changed settings to allow other, not so friendly names, to be used.
This is not the first time Apple has updated Siri quietly. Previously, Siri would tell users that the Lumia 900 was the best smartphone. Apple disagreed, and changed Siri"s response to reply that the iPhone 4S was the best smartphone. Even after Apple"s silent change, Siri still secretly wanted you to be using a Lumia 900.
