1.第一步导入framework
2.导入头文件
#import <AVFoundation/AVSpeechSynthesis.h>
3. 设置代理 并写下面方法 （注：代理方法用不到可以不用 遵循代理 和代理方法）
//遵循代理 AVSpeechSynthesizerDelegate
// 文本读语音方法 stra是要读的文本
- (void)boFangTextWithString:(NSString *)stra
{
//初始化语音合成器
_avSpeaker = [[AVSpeechSynthesizer alloc] init];
_avSpeaker.delegate = self;
//初始化要说出的内容
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:stra];
//设置语速,语速介于AVSpeechUtteranceMaximumSpeechRate和AVSpeechUtteranceMinimumSpeechRate之间
//AVSpeechUtteranceMaximumSpeechRate
//AVSpeechUtteranceMinimumSpeechRate
//AVSpeechUtteranceDefaultSpeechRate
utterance.rate = 0.5; //设置音高,[0.5 - 2] 默认 = 1
//AVSpeechUtteranceMaximumSpeechRate
//AVSpeechUtteranceMinimumSpeechRate
//AVSpeechUtteranceDefaultSpeechRate
utterance.pitchMultiplier = ; //设置音量,[0-1] 默认 = 1
utterance.volume = ; //读一段前的停顿时间
utterance.preUtteranceDelay = ;
//读完一段后的停顿时间
utterance.postUtteranceDelay = ; //设置声音,是AVSpeechSynthesisVoice对象
//AVSpeechSynthesisVoice定义了一系列的声音, 主要是不同的语言和地区.
//voiceWithLanguage: 根据制定的语言, 获得一个声音.
//speechVoices: 获得当前设备支持的声音
//currentLanguageCode: 获得当前声音的语言字符串, 比如”ZH-cn”
//language: 获得当前的语言
//通过特定的语言获得声音
AVSpeechSynthesisVoice *voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"zh-CN"];
//通过voicce标示获得声音
//AVSpeechSynthesisVoice *voice = [AVSpeechSynthesisVoice voiceWithIdentifier:AVSpeechSynthesisVoiceIdentifierAlex];
utterance.voice = voice;
//开始朗读
[_avSpeaker speakUtterance:utterance];
}
#pragma mark - AVSpeechSynthesizerDelegate
//已经开始
- (void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didStartSpeechUtterance:(AVSpeechUtterance *)utterance{ }
//已经说完
- (void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didFinishSpeechUtterance:(AVSpeechUtterance *)utterance{ //如果朗读要循环朗读，可以在这里再次调用朗读方法
//[_avSpeaker speakUtterance:utterance];
}
//已经暂停
- (void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didPauseSpeechUtterance:(AVSpeechUtterance *)utterance{ }
//已经继续说话
- (void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didContinueSpeechUtterance:(AVSpeechUtterance *)utterance{ }
//已经取消说话
- (void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didCancelSpeechUtterance:(AVSpeechUtterance *)utterance{ }
//将要说某段话
- (void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer willSpeakRangeOfSpeechString:(NSRange)characterRange utterance:(AVSpeechUtterance *)utterance{ }
