HS-SC: Homophonic Substitution in Simplified Chinese

简体中文的同音替换

The function of this script is to replace the Simplified Chinese characters entered by the user with other common Simplified Chinese characters with the same pronunciation and tone. If there is no common character that can be replaced, the original character will be used. Each replaced character is preceded and followed by a space. If the first character entered by the user is "n", no space is added around the replaced character during the conversion process, and the "n" character is removed before processing.

Usage:

pip install pypinyin
pip install pyperclip
python HS-SC.py

Script Explanation:

Initialise the pinyin-to-character mapping:

Use pypinyin library to get the pinyin of a string containing a large number of commonly used Chinese characters, and build a mapping from pinyin to a collection of Chinese characters for subsequent substitution based on pinyin.

Define the replacement function:

The replace_with_different_common_char function is responsible for replacing a character. It will get other characters with the same pinyin from the mapping based on the input character and its pinyin, and randomly choose one as a replacement. If the input character itself is among the candidate characters, then it will remove it first to avoid replacing it with the same character. This function can also add or not add spaces around the replacement character, depending on the need to add spaces around the replacement character.

Define the convert function:

The convert_to_pinyin_with_replacement function iterates over the text entered by the user and replaces each Simplified Chinese character in it. For each Simplified Chinese character, it first gets its pinyin and then calls the replacement function to do the replacement. Non-Simplified Chinese characters remain unchanged.

Get user input and set space flag:

Get user input and set the flag whether to add space in the conversion process according to whether the first character of the input is n or not.

Execute conversion and output the result:

Performs the conversion operation and outputs the converted text. If Add Spaces is selected, spaces will be added around the replaced characters in the converted text. Finally, copy the converted text to the clipboard.

Shortcomings:

• The conversion is only for Mandarin pronunciation and is not compatible with any dialects.

• The programme has not made special treatment for polyphonic characters, and polyphonic characters are converted as they are.

• There is no GUI.
