集团新近付出之一个微信语音红包,就是前方哪一天间相比较火之保你说红包小程序。咋样增强识另外精准度呢。

 在说精准度往日,先盖说下总体语音识其它开发流程。前面我起成文都说及过了。具体我即便非语了。一画带过。

 
先是透过微序前端调动语音录制效用以到客户说之语音,比如mp4格式,然后经百度的话音识别算法,转为文字。具体看百度语音识其余接口。地址http://yuyin.baidu.com/docs/asr/188

   重返的格式如下:

  1. // 成功返回
  2. {
  3. "err_no": 0,
  4. "err_msg": "success.",
  5. "corpus_no": "15984125203285346378",
  6. "sn": "481D633F-73BA-726F-49EF-8659ACCC2F3D",
  7. "result": ["北京天气"]
  8. }

 
json格式的,取到他的字来,然后跟你的语音红包文字举行匹配,匹配对了,就得尽快到是语音红包了。

 
好了,问题来了,假诺光所以粤语举行匹配,就会师起,比如我们说的当儿,我们从一个字,比如lianhe
会出现过剩只词组,比如同 连和 联和  莲河  那么具体是孰也?

 
 我们前支付的首先只本子,大家就境遇这坑了,当时一个客户是如连和,可是也,百度识别一向被你识另外凡一道。这虽于丁围捕狂了。客户直接抢不至红包。不过自说是说对了呀。这怎么处置呢?产品经营将题目提过来了。技术员,看看您怎么化解了?

 
 嗯,临危受命,大家思想技术怎么来化解吧。于是想到的措施就是是零星种植:

1、将亲笔转为拼音,匹配这半独的拼音是否一律。

2、拼音可能会合遇上南方人同北部人口之界别,比如是否暴发后鼻音的题材。
 beijing  和beijin  
没有后鼻音的。那么即使拿拼音作为一个单元,比如一个词组,假使有10个假名,我们安概率,只要80%之准确率固然答对了。

 

 
使用方面这半只章程成功将是题目迎刃而解了。所以要就是是仿怎么转为拼音了。我们能够去百度搜来相关的类库函数,直接调用就可了。

 
我这边呢分享一个本人自己于于是的。我们需要能够间接复制利用。还不错哦。也是自百度搜的,旁人写的一个类库。
