Ever since we use computers, people have dreamt of interacting with computers in a natural way, using spoken language. Hardly any science fiction flick gets by without humans talking to computers or even androids. With Siri, Apple has brought this capability to iOS. Many developers hoped to use Siri I their apps, but so far Apple hasn’t provided us with an API. In this talk, I will show how to use speech recognition and speech synthesis in native iOS applications without having to jailbreak your device. We will take a look at some libraries (both open source and commercial) that allow us to build speech-enabled apps with little effort.
