Research and Implementation of Sixian Hakka Pinyin Input Method for Mobile Cell APP

本論文研究智慧型的客語拼音輸入法為一基於Android輸入法框架（Input Method Framework，IMF），使用者能在任何文書的APP（Application，APP）輸入客語文字。使用者輸入客語單字或客語詞彙拼音縮寫時，輸入法會依照使用者的輸入搜尋儲存於Android上的SQLite資料庫的單字拼音對照字庫、縮寫詞對照詞庫及前後詞對照詞庫，根據搜尋的結果產生出候選字或候選詞彙，提供使用者選擇輸出。單字拼音字庫和縮寫詞對照詞庫分別包含9361個字數及32453個詞彙數；客語音檔資料庫包含單音節檔2427、詞彙檔3392及靜音檔27，總計5846。除了基本的客語拼音輸入外，輸入法本身提供了幾種功能：（1）使用者偏好輸入：記錄使用者平常輸入的字詞，目的讓使用者能依照自己偏好更快速將常用的字或詞彙做輸出。（2）客語詞字首快速輸入：使用者可透過縮寫詞對照詞庫內搜尋字母，快速得到該客語詞，節省打字次數。（3）前後詞預測輸出：此功能具備了讓使用者快速輸出客語句，讓客語詞彙或句達到更快輸出的效率，並訓練出客語的前後詞bi-gram。（4）客語詞人聲發音：此目的是讓客語初學者能聽到正確的客語拼音唸出，達到學習的目的。
