iOS 原生語音播報(bào)的使用

注：原生的語音播報(bào)功能是在7.0以后才出現(xiàn)的呻疹，在使用時(shí)要注意判斷當(dāng)前版本號(hào)吃引。

一、實(shí)現(xiàn)語音播報(bào)相關(guān)方法

1刽锤、在使用播報(bào)功能的類中引入“頭文件”（required）或“代理”（optional）

#import <AVFoundation/AVFoundation.h>

@interface ViewController ()<AVSpeechSynthesizerDelegate>{

AVSpeechSynthesizer *_synthesizer;

}

2镊尺、開始語音播報(bào)

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

NSString *broadCastStr = @"承德避暑山莊又名“承德離宮”或“熱河行宮”，位于河北省承德市中心北部并思，武烈河西岸一帶狹長(zhǎng)的谷地上庐氮，是清代皇帝夏天避暑和處理政務(wù)的場(chǎng)避暑山莊始建于1703年，歷經(jīng)清康熙宋彼、雍正弄砍、乾隆三朝，耗時(shí)89年建成输涕。避暑山莊以樸素淡雅的山村野趣為格調(diào)音婶，取自然山水之本色，吸收江南塞北之風(fēng)光占贫，成為中國(guó)現(xiàn)存占地最大的古代帝王宮苑";

[self voiceBroadCastStr:broadCastStr];

}

//content代表要播報(bào)的內(nèi)容

-(void)voiceBroadCastStr:(NSString *)content

{

//初始化語音播報(bào)桃熄，控制播放先口、暫停

_synthesizer = [[AVSpeechSynthesizer alloc]init];

//語音對(duì)象型奥，說中文（zh_CN）瞳收，英文(en-US)

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

// 實(shí)例化發(fā)聲的對(duì)象，及朗讀的內(nèi)容

AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:content];

//指定語音類型

utterance.voice = voiceType;

utterance.rate = 0.4;

utterance.volume = 1.0;

_synthesizer.delegate = self;//注意：代理方法寫在啟動(dòng)前

[_synthesizer speakUtterance:utterance];//啟動(dòng)

}

3厢汹、暫停語音播報(bào)

[_synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];

4螟深、繼續(xù)語音播報(bào)

[_synthesizer continueSpeaking];

5、取消或停止語音播報(bào)

/**

*AVSpeechBoundaryImmediate,? 立即停

AVSpeechBoundaryWord? 說完一個(gè)整詞再停

*/

[_synthesizer stopSpeakingAtBoundary:AVSpeechBoundaryImmediate];


二烫葬、語音播報(bào)相關(guān)類

1界弧、AVSPeechSynthesizer：用于控制語音播報(bào)的“開始”，“暫痛钭郏”垢箕，“繼續(xù)”，“停止,”;且含有代理兑巾，幫助我們監(jiān)聽當(dāng)前語音的播報(bào)狀態(tài)条获。

2、AVSpeechUtterance(發(fā)聲的對(duì)象)：用于指定播報(bào)的內(nèi)容蒋歌，語言的屬性\voice帅掘，播報(bào)的速率\rate，播報(bào)的音量\voiume堂油，以及音高\(yùn)pitchMultiplier

3修档、AVSpeechSynthesisVoice: 用于設(shè)置語音的屬性，包括語言類型/language,語音播報(bào)者名稱/name,語音的標(biāo)識(shí)/identifier,以及quality府框。

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

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