iOS 原生语音播报的使用

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。

一、实现语音播报相关方法

1、在使用播报功能的类中引入“头文件”（required）或“代理”（optional）

#import <AVFoundation/AVFoundation.h>

@interface ViewController ()<AVSpeechSynthesizerDelegate>{

AVSpeechSynthesizer *_synthesizer;

}

2、开始语音播报

if ([[[UIDevice currentDevice]systemVersion]integerValue]>=7.0) {

NSString *broadCastStr = @"承德避暑山庄又名“承德离宫”或“热河行宫”，位于河北省承德市中心北部，武烈河西岸一带狭长的谷地上，是清代皇帝夏天避暑和处理政务的场避暑山庄始建于1703年，历经清康熙、雍正、乾隆三朝，耗时89年建成。避暑山庄以朴素淡雅的山村野趣为格调，取自然山水之本色，吸收江南塞北之风光，成为中国现存占地最大的古代帝王宫苑";

[self voiceBroadCastStr:broadCastStr];

}

//content代表要播报的内容

-(void)voiceBroadCastStr:(NSString *)content

{

//初始化语音播报，控制播放、暂停

_synthesizer = [[AVSpeechSynthesizer alloc]init];

//语音对象，说中文（zh_CN），英文(en-US)

AVSpeechSynthesisVoice *voiceType = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh_CN"];

// 实例化发声的对象，及朗读的内容

AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:content];

//指定语音类型

utterance.voice = voiceType;

utterance.rate = 0.4;

utterance.volume = 1.0;

_synthesizer.delegate = self;//注意：代理方法写在启动前

[_synthesizer speakUtterance:utterance];//启动

}

3、暂停语音播报

[_synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];

4、继续语音播报

[_synthesizer continueSpeaking];

5、取消或停止语音播报

/**

*AVSpeechBoundaryImmediate, 立即停

AVSpeechBoundaryWord 说完一个整词再停

[_synthesizer stopSpeakingAtBoundary:AVSpeechBoundaryImmediate];

二、语音播报相关类

1、AVSPeechSynthesizer：用于控制语音播报的“开始”，“暂停”，“继续”，“停止,”;且含有代理，帮助我们监听当前语音的播报状态。

2、AVSpeechUtterance(发声的对象)：用于指定播报的内容，语言的属性\voice，播报的速率\rate，播报的音量\voiume，以及音高\pitchMultiplier

3、AVSpeechSynthesisVoice: 用于设置语音的属性，包括语言类型/language,语音播报者名称/name,语音的标识/identifier,以及quality。

/*例如：language:zh-CN name:Li-mu quality:1

identifier:com.apple.ttsbundle.siri_male_zh-CN_compact*/

/*支持的所有声音

三、AVSpeechSynthesizerDelegate：用于监听语音播报状态

-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didStartSpeechUtterance:(AVSpeechUtterance *)utterance

{

NSLog(@"已经开始播报");NSLog(@"判断播报状态%u\n%u",_synthesizer.isSpeaking,_synthesizer.isPaused);//1,0

}

-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didPauseSpeechUtterance:(AVSpeechUtterance *)utterance

}

-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didFinishSpeechUtterance:(AVSpeechUtterance *)utterance

{

NSLog(@"已经完成播报");

NSLog(@"判断播报状态%u\n%u",_synthesizer.isSpeaking,_synthesizer.isPaused);//0,0

}

-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didCancelSpeechUtterance:(AVSpeechUtterance *)utterance

{

NSLog(@"已经停止播报");

}

-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didContinueSpeechUtterance:(AVSpeechUtterance *)utterance

{

NSLog(@"继续播报");
