iOS: 讯飞语音的使用

简介:

一、介绍:

讯飞语音做的相当不错,容错率达到90%多,如果需要做语音方面的功能,它绝对是一个不错的选择。讯飞语音的功能很多:语音听写、语音识别、语音合成等,但我们最常用的还是语音听写。讯飞语音中包含界面的语音听写和不带界面的语音听写,下面我来演示一下。

 

二、准备工作:

(1)去讯飞语音开发平台注册账号并登陆,然后在控制台创建应用,获取对应的app id,这个以后使用它注册激活讯飞语音。

(2)下载讯飞语音SDK,将其拖入到项目中,然后添加需要所有的依赖库,另外还有新添加库Contacts.framework,编译运行即可。

(3)引入头文件,以及遵从代理,激活讯飞语音,并实现功能。

 

三、BitCode 设置

在 Xcode 7 默认开启了 Bitcode,Bitcode 需要工程依赖的类库同时支持。而语记 SDK 暂时还不支持Bitcode,所以可以先临时关闭。后续支持 Bitcode 请关注讯飞开放平台版本更新,QQ 群中也会􏰁醒。在 Targets - Build Settings 中搜索 Bitcode 即可,找 到相应选项,设置为 NO。

 

四、演示:

第一种不带界面的语音听写:

DDHomeSearchViewController.m

复制代码
#import <UIKit/UIKit.h>
#import "iflyMSC/iflyMSC.h"
#import "iflyMSC/IFlySpeechRecognizerDelegate.h"
#import "iflyMSC/IFlySpeechRecognizer.h"

@interface DDHomeSearchViewController : UIViewController<IFlySpeechRecognizerDelegate>
@property (nonatomic, strong) IFlySpeechRecognizer *iFlySpeechRecognizer;   //不带界面的识别对象
@end

//初始化Appid
-(void)initAppId
{
    NSString *initString = [[NSString alloc] initWithFormat:@"appid=%@",@"xxxxxxx"];
    [IFlySpeechUtility createUtility:initString];
}

//初始化识别器
-(void)initRecognizer
{
    //单例模式,无UI的实例
    if (_iFlySpeechRecognizer == nil) {
    _iFlySpeechRecognizer = [IFlySpeechRecognizer sharedInstance];
    }

    // 设置参数
    if (_iFlySpeechRecognizer != nil) {
    //扩展参数
    [_iFlySpeechRecognizer setParameter:@"" forKey:[IFlySpeechConstant PARAMS]];
    //设置听写模式
    [_iFlySpeechRecognizer setParameter:@"iat" forKey:[IFlySpeechConstant IFLY_DOMAIN]];
    //设置最长录音时间
    [_iFlySpeechRecognizer setParameter:@"30000" forKey:[IFlySpeechConstant SPEECH_TIMEOUT]];
    //设置后端点
    [_iFlySpeechRecognizer setParameter:@"1800" forKey:[IFlySpeechConstant VAD_EOS]];
    //设置前端点
    [_iFlySpeechRecognizer setParameter:@"1800" forKey:[IFlySpeechConstant VAD_BOS]];
    //网络等待时间
    [_iFlySpeechRecognizer setParameter:@"20000" forKey:[IFlySpeechConstant NET_TIMEOUT]];
    //设置采样率,推荐使用16K
    [_iFlySpeechRecognizer setParameter:@"16000" forKey:[IFlySpeechConstant SAMPLE_RATE]];
    //设置语言
    [_iFlySpeechRecognizer setParameter:@"zh_cn" forKey:[IFlySpeechConstant LANGUAGE]];
    //设置方言
    [_iFlySpeechRecognizer setParameter:@"mandarin" forKey:[IFlySpeechConstant ACCENT]];
    //设置是否返回标点符号
    [_iFlySpeechRecognizer setParameter:@"1" forKey:[IFlySpeechConstant ASR_PTT]];
    //设置数据返回格式
    [_iFlySpeechRecognizer setParameter:@"plain" forKey:[IFlySpeechConstant RESULT_TYPE]];

    }

    // 设置代理
    _iFlySpeechRecognizer.delegate = self;
}


//实现代理方法
// 出现错误
- (void) onError:(IFlySpeechError *) error
{
    NSLog(@"出现错误 :%@",error);
}

// 识别结果 
- (void) onResults:(NSArray *) results isLast:(BOOL)isLast
{
    NSMutableString *result = [[NSMutableString alloc] init];
    NSDictionary *dic = [results objectAtIndex:0];
    for (NSString *key in dic) {
        [result appendFormat:@"\n\n------ %@ (置信度:%@) ------ \n\n",key,[dic objectForKey:key]];
    }

    // 忽略结束。号
    if ([result hasPrefix:@"\n\n------ 。"]) {
        return;
    }

    NSLog(@"%@",result);
}


//点击开始和结束
- (IBAction)understand:(id)sender
{   
    // 开始识别
    [_iFlySpeechRecognizer startListening];
}

- (IBAction)finish:(id)sender
{   
    // 停止识别
    [_iFlySpeechRecognizer stopListening];
}


//初始化
- (void)viewDidLoad {
    [super viewDidLoad];
    [self initAppId];
    [self initRecognizer];
}

达摩院智能语音交互 - 声纹识别技术
声纹识别是基于每个发音人的发音器官构造不同,识别当前发音人的身份。按照任务具体分为两种: 声纹辨认:从说话人集合中判别出测试语音所属的说话人,为多选一的问题 声纹确认:判断测试语音是否由目标说话人所说,是二选一的问题(是或者不是) 按照应用具体分为两种: 文本相关:要求使用者重复指定的话语,通常包含与训练信息相同的文本(精度较高,适合当前应用模式) 文本无关:对使用者发音内容和语言没有要求,受信道环境影响比较大,精度不高 本课程主要介绍声纹识别的原型技术、系统架构及应用案例等。 讲师介绍: 郑斯奇,达摩院算法专家,毕业于美国哈佛大学,研究方向包括声纹识别、性别、年龄、语种识别等。致力于推动端侧声纹与个性化技术的研究和大规模应用。
