iOS 文字转语音

本文只做简单的记录

1. 首先导入 AVFoundation.famework

2.  导入#import  <AVSpeechSynthesis.h>头文件  遵守协议<AVSpeechSynthesizerDelegate>    

.h 文件代码

#import

NS_ASSUME_NONNULL_BEGIN

@interfaceTKYSoundPlayer :NSObject

+ (instancetype)shareSoundPlayerInit;

//传入要播放的字符串

- (void)play:(NSString*)string;

//暂停

- (void)pausePlay;

//从头开始播放

- (void)againPlay;

@end

.m 文件

#import "TKYSoundPlayer.h"

#import

@interface TKYSoundPlayer()<AVSpeechSynthesizerDelegate>

    AVSpeechSynthesizer *synth;

@end

 staticTKYSoundPlayer*soundplayer =nil;

@implementation TKYSoundPlayer

    }

    return soundplayer;

}

- (void)play:(NSString*)string{

     if([synthisPaused]) {

            //如果暂停则恢复，会从暂停的地方继续

            [synth continueSpeaking];

        }else{

            //需要转换的文字

            AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:string];

            utterance.rate = 0.5; // 设置语速，范围0-1，注意0最慢，1最快；（AVSpeechUtteranceMinimumSpeechRate最慢，AVSpeechUtteranceMaximumSpeechRate最快）

            synth = [[AVSpeechSynthesizer alloc] init];

            synth.delegate=self;//设置代理

            //获取当前系统语音

            NSString*preferredLang =@"";

            //设置发音，这是中文普通话

        }

}

- (void)pausePlay{

}

- (void)againPlay{
