iOS7 的这个功能确实不错。我刚试了下，用官方提供的API ，简单的几句代码就能实现文本转语音！

Xcode 5.0 

工程建好后首先把AVFoundation.framework 加入到工程

 AVSpeechSynthesizer *av = [[AVSpeechSynthesizer alloc]init];
    AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc]initWithString:@"Hello qingjoin"]; //需要转换的文本
    [av speakUtterance:utterance];
//以上三行代码就可以搞定文本转语音   有API就是省事。哈哈

//具体可参考以下demo   记得.h文件里别忘记了这个哦
#import <AVFoundation/AVSpeechSynthesis.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    _textS.delegate = self;
     // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)textToSpeechBtnPress:(id)sender
{
    AVSpeechSynthesizer *av = [[AVSpeechSynthesizer alloc]init];
    AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc]initWithString:_textS.text];  //需要转换的文本
    [av speakUtterance:utterance];
}

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

@end
