对于中文文本的排序，我想将汉字转换为拼音，正确分离每个汉字并将连续的字符组合在一起。
通过提供执行此操作的逻辑或源代码，您能帮助我完成此任务吗？
如果有任何开源或lib已经存在，请告诉我。
简短的回答：你没有。
Long answer: There is no one-to-one mapping for 汉字 to 汉语拼音. Just some quick examples:
等等。我有一本关于这个主题的初学者书，里面有207个例子。我强调这是一本初学者的书，并不完整。每个人都有一两页使用和条件的例子，您可以根据这些例子选择合适的发音。它不是易于编程的东西（如果有的话）。
这甚至没有解决你想要处理的其他问题：将字符分成分组的单词。一句话的概念在中文中有点滑。 （有两个术语对应，大致相当于中文中的“单词”，例如：字和词。第一个是字符，第二个字符组合在一起构成一个概念。（我经常被中国人问到有多少当他们真正意为“人物”时，我可以阅读“单词”。）虽然在某些情况下区别很明显（例如，“乌鸦”一词是“乌鸦” - 两个字必须在一起才能恰当地表达这个想法将它翻译为“黑鸦”是不正确的，在其他人中它不是那么清楚。“你好”是什么意思？它是一个词的意思，惯用，“你好”？还是两个词翻译字面意思是“你好”？所涉及的每个角色都是独立的或与其他词汇成组的，但它们在一起意味着与他们各自的意义完全不同的东西。鉴于此，你是如何准确地将汉语拼音音译分组的（一开始很难做到这一点！）进入“言语”？
包含unicode到拼音之间映射的表
ftp://ftp.cuhk.hk/pub/chinese/ifcss/software/data/Uni2Pinyin.gz
CoreFoundation提供了一些转换方法：
CFMutableStringRef string = CFStringCreateMutableCopy(NULL, 0, CFSTR("中文"));
CFStringTransform(string, NULL, kCFStringTransformMandarinLatin, NO);
CFStringTransform(string, NULL, kCFStringTransformStripDiacritics, NO);
NSLog(@"%@", string);
输出是
zhong wen
虽然@JUST MY correct OPINION's answer解决了将字符转换为拼音的一些困难，但这不是一个不可能解决的问题。
我有written a library (pinyinify)以正确的准确度解决了这个任务。即使字符和拼音之间没有一对一的映射，我的库通常可以决定哪个发音是正确的。例如，“我受不了了”正确地转换为“wǒshòubùliǎoe”，其中有两个不同的发音。
我解决问题的方法很简单：
下面用C＃编写的代码可以帮助你简单地将包含在gb2312 encodec中的中文单词（通常使用的简体中文单词的2312个）转换为拼音。将“今天天气不错”转换为“JinTianTianQiBuCuo”。
有时一个中文单词不是一对一映射到拼音，这取决于我们谈论的上下文。就像“自行车”（自行车）中的“行”发音为“兴”，但在“银行”（银行）它发音为“Hang”。如果您对此有疑问，您可能会发现更复杂的解决方案来处理这个问题。
抱歉我的英语很差。我希望这可以给你一些帮助。

我遇到了这个问题，我在PHP中找到了一个解决方案（我想它可能更清洁，但它有效）。我遇到了一些麻烦，因为本主题中给出的文件来自hexa unicode。
1）将数据从ftp://ftp.cuhk.hk/pub/chinese/ifcss/software/data/Uni2Pinyin.gz（感谢pierr）导入您的数据库或其他任何内容
2）将数据作为$pinyinArray[$hexaUnicode] = $pinyin;导入数组
3）使用此代码：
/*
* Decimal representation of $c
* function found there: http://www.cantonese.sheik.co.uk/phorum/read.php?2,19594
*/
function uniord($c)
{
$ud = 0;
if (ord($c{0})>=0 && ord($c{0})<=127)
$ud = $c{0};
if (ord($c{0})>=192 && ord($c{0})<=223)
$ud = (ord($c{0})-192)*64 + (ord($c{1})-128);
if (ord($c{0})>=224 && ord($c{0})<=239)
$ud = (ord($c{0})-224)*4096 + (ord($c{1})-128)*64 + (ord($c{2})-128);
if (ord($c{0})>=240 && ord($c{0})<=247)
$ud = (ord($c{0})-240)*262144 + (ord($c{1})-128)*4096 + (ord($c{2})-128)*64 + (ord($c{3})-128);
if (ord($c{0})>=248 && ord($c{0})<=251)
$ud = (ord($c{0})-248)*16777216 + (ord($c{1})-128)*262144 + (ord($c{2})-128)*4096 + (ord($c{3})-128)*64 + (ord($c{4})-128);
if (ord($c{0})>=252 && ord($c{0})<=253)
$ud = (ord($c{0})-252)*1073741824 + (ord($c{1})-128)*16777216 + (ord($c{2})-128)*262144 + (ord($c{3})-128)*4096 + (ord($c{4})-128)*64 + (ord($c{5})-128);
if (ord($c{0})>=254 && ord($c{0})<=255) //error
$ud = false;
return $ud;
}
/*
* Translate the $string string of a single chinese charactere to unicode
*/
function chineseToHexaUnicode($string) {
return strtoupper(dechex(uniord($string)));
}
/*
*
*/
function convertChineseToPinyin($string,$pinyinArray) {
$pinyinValue = '';
for ($i = 0; $i < mb_strlen($string);$i++)
$pinyinValue.=$pinyinArray[chineseToHexaUnicode(mb_substr($string, $i, 1))];
return $pinyinValue;
}
$string = '龙江省五大';
echo convertChineseToPinyin($string,$pinyinArray);
回声：(long2)(jiang1)(sheng3,xing3)(wu3)(da4,dai4)
当然，$pinyinArray是你的数据数组（hexoUnicode => pinyin）
希望它会帮助某人。
您可以使用以下方法：
from __future__ import unicode_literals
from pypinyin import lazy_pinyin
hanzi_list = ['如何', '将', '汉字','转为', '拼音']
pinyin_list = [''.join(lazy_pinyin(_)) for _ in hanzi_list]
输出：
['ruhe', 'jiang', 'hanzi', 'zhuanwei', 'pinyin']
如果您使用Visual Studio，这可能是一个选项：
Microsoft.International.Converters.PinYinConverter
如何安装：
首先，下载Visual Studio International Pack 2.0，官方下载。下载完成后，安装运行文件VSIPSetup.msi安装（默认安装目录下的x86操作系统（C：\ Program Files \ Microsoft Visual Studio International Feature Pack 2.0）。安装完成后，需要在VS中添加引用，分别参考：C：\ Program Files \ Microsoft Visual Studio International Pack \简体中文拼音转换库（拼音）和C：\ Program Files \ Microsoft Visual Studio International Pack \繁体中文到简体中文转换库和插件工具（传统和简体的转转到）
如何使用：
public static string GetPinyin(string str)
{
string r = string.Empty;
foreach (char obj in str)
{
try
{
ChineseChar chineseChar = new ChineseChar(obj);
string t = chineseChar.Pinyins[0].ToString();
r += t.Substring(0, t.Length - 1);
}
catch
{
r += obj.ToString();
}
}
return r;
}
