一、需求与需求分析

        根据语音辨认到的人名匹配应用内联系人并拨打电话。
        经调研总结了以下几种常用的处理方法：
        （1）pinyin4j(开源库)
        （2）jpinyin(开源库)
        （3）ASCII码映射
二、pinyin4j

        支持多种拼音系统（简体和繁体），包罗汉语拼音、通用拼音、威妥玛拼音、MPS2、耶鲁拼音和国语拼音。支持多种发音和自定义输出。
        查看源码发现入参仅支持 char 类型。不太符合要求，继续探求pinyin4j升级版=》jpinyin。

三、jpinyin


        JPinyin是一个汉字转拼音的Java开源类库，在PinYin4j的功能基础上做了一些改进。
3.1 JPinyin主要特性

        1、正确、完善的字库；Unicode编码从4E00-9FA5范围及3007（〇）的20903个汉字中，JPinyin能转换除46个异体字（异体字不存在尺度拼音）之外的全部汉字；
        2、拼音转换速度快；经测试，转换Unicode编码从4E00-9FA5范围的20902个汉字，JPinyin耗时约100毫秒。
        3、多拼音格式输出支持；JPinyin支持多种拼音输出格式：带音标、不带音标、数字表现音标以及拼音首字母输出格式；
        4、常见多音字辨认；JPinyin支持常见多音字的辨认，此中包罗词组、成语、地名等；
        5、简繁体中文转换；
        6、支持添加用户自定义字典；
3.2 集成

        app/build.gradle
   implementation 'com.github.stuxuhai:jpinyin:1.1.7'
  3.3 利用及效果

1.         var content:String = binding!!.etContent.text.toString()
2.         //上海 重庆 重量 长安 长大
3.         if (!StringUtils.isEmpty(content)) {
4.             // shànghǎi chóngqìng zhòngliàng chángān chángdà
5.             PinyinHelper.convertToPinyinString(content, "", PinyinFormat.WITH_TONE_MARK)
6.             // shang4hai3 chong2qing4 zhong4liang4 chang2an1 chang2da4
7.             PinyinHelper.convertToPinyinString(content, "", PinyinFormat.WITH_TONE_NUMBER)
8.             // shanghai chongqing zhongliang changan changda
9.             PinyinHelper.convertToPinyinString(content, "", PinyinFormat.WITHOUT_TONE)
10.             // sh cq zl ca cd
11.             PinyinHelper.getShortPinyin(content)
12.         }

复制代码

        重庆和重量辨认到了 chóngqìng zhòngliàng。
        长安和长大辨认异常 changan changda。
        这个辨认效果就看产品评估一下能不能给过了？
四、ASCII码映射

        长处：利用这个方法只必要一个类就可以搞定了，方便简朴，无需添加依赖。
        缺点：相对于之前介绍的两种开源库来说，这种方法没那么强大，只能获取一些简朴的汉字拼音。
