Yes, with iOS 7, The AVSpeechSynthesizer class produces synthesized speech from text on an iOS device, and provides methods for controlling or monitoring the progress of ongoing speech.

EDIT: Simply add AVFoundation framework in your project, Add the import statement #import <AVFoundation/AVFoundation.h> and execute this piece of code:

AVSpeechSynthesizer *speechSynthesizer = [[AVSpeechSynthesizer alloc]init];
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Really, its very easy."];
[utterance setRate:0.5f];
[speechSynthesizer speakUtterance:utterance];
