偶然发现的原生的语音播报，简单的看一下：
注：原生的语音播报功能是在7.0以后才出现的，在使用时要注意判断当前版本号。
语音播报的三个类：
AVSpeechSynthesizer、AVSpeechUtterance、AVSpeechSynthesisVoice
AVSpeechSynthesizer : 用于控制语音播报的开始、暂停、继续和停止 —— 有代理，监听播报状态;
AVSpeechUtterance : 播报声音的对象 ： 指定播报内容，语速设置 、 声音大小设置等;
AVSpeechSynthesisVoice : 设置声音的属性 ： 语言类型、播报者名称等;
1、首先导入头文件：
#import <AVFoundation/AVFoundation.h>
@interface ViewController ()<AVSpeechSynthesizerDelegate>{
// 用于控制语音播报的开始、暂停、继续和停止 —— 有代理，监听播报状态
AVSpeechSynthesizer *_synthesizer;// 播报声音的对象 ： 指定播报内容，语速设置 、 声音大小设置等
AVSpeechUtterance *_utterance;
// 设置声音的属性 ： 语言类型、播报者名称等
AVSpeechSynthesisVoice *_voiceType;
}2、设置播报的内容：
- (void)viewDidLoad {
[super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib.
self.playContentStr = @"自然地理是研究自然地理环境的组成、结构、功能、动态及其空间分异规律的学科，是地理学的一个重要分支学科。综合性的分支科学有综合自然地理学、区域自然地理学、古地理学等。部门性的分支科学有地貌学、气候学、水文地理学、生物地理学、冰川学等。狭义的自然地理学仅指综合自然地理学，部门自然地理学已逐步发展成为一门独立的学科。狭义的自然地理学仅指综合自然地理学。";
//初始化语音播报，控制播放、暂停
_synthesizer = [[AVSpeechSynthesizer alloc]init];
_synthesizer.delegate = self;//注意：代理方法写在启动前
//语音对象，说中文（zh_CN），英文(en-US)
_voiceType = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh_CN"];
// 实例化发声的对象，及朗读的内容 --- 发声对象
_utterance = [AVSpeechUtterance speechUtteranceWithString:self.playContentStr];
//指定语音类型
_utterance.voice = _voiceType; // 语音的播放速度
// utterance.rate = 1;
_utterance.volume = 1.0;
}3、开始播报：
- (IBAction)starPlay:(id)sender { if ([[[UIDevice currentDevice]systemVersion]integerValue]>=7.0) {
[_synthesizer speakUtterance:_utterance];//启动
}
}4、暂停播报：
/*
* AVSpeechBoundaryImmediate, 立即停止
*
*
* AVSpeechBoundaryWord 说完一个整词再停
*
*/- (IBAction)pausePlay:(id)sender {
[_synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];
}5、继续播报和停止播报：
- (IBAction)resumePlay:(id)sender {
[_synthesizer continueSpeaking];
}
- (IBAction)stopPlay:(id)sender {
[_synthesizer stopSpeakingAtBoundary:AVSpeechBoundaryImmediate];
}代理方法 —— 监听 播报状态
#pragma mark - AVSpeechSynthesizer的代理方法 - 监听状态-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didStartSpeechUtterance:(AVSpeechUtterance *)utterance {
NSLog(@"已经开始播报"); //1,0

}

}

{

}

}
-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer willSpeakRangeOfSpeechString:(NSRange)characterRange utterance:(AVSpeechUtterance *)utterance
