Voice Actions is an advanced virtual assistant
for Androids and iPhones. It is comparable to Apples Siri but also lets you make phone calls, write e-mails, send sms, access information and do many more tasks on Android and iPhone devices. Information retrieval is done in a hierarchic fashion, so when people ask for the definition of abstinence the result comes directly from Wikipedia without bothering the APIs of Yahoo Answers, ChaCha, answers.com, pandorabot, cleverbot or other services.
This robot is deeply integrated into the android system, so that settings can be queried and changed via voice as well.
