iOS7 文本转语音 AVSpeechSynthesizer

OS7 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 ()

@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;

}
