How to convert Chinese characters to Pinyin

Question

For sorting Chinese language text, I want to convert Chinese characters to Pinyin, properly separating each Chinese character and grouping successive characters together.

Answer 1

i had this problem and i found a solution in PHP (which could be cleaner i suppose but it works). I had some troubles because the file given in this topic is from hexa unicode.

1) Import the data from ftp://ftp.cuhk.hk/pub/chinese/ifcss/software/data/Uni2Pinyin.gz (thanks pierr) to your database or whatever

2) Import your data in an array as $pinyinArray[$hexaUnicode] = $pinyin;

3) Use this code:

/*
 * 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);

echo: (long2)(jiang1)(sheng3,xing3)(wu3)(da4,dai4)

Of course, $pinyinArray is your array of data (hexoUnicode => pinyin)

Hope it will help someone.

Answer 2

You can use the following method:

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]

Output:

['ruhe', 'jiang', 'hanzi', 'zhuanwei', 'pinyin']
