    Abstract: 本論文研究主題為針對語音辨識中的特徵值擷取部分進行改良。特徵值擷取在語音辨識上是很重要的一個部分,具有降低資料量與突顯聲音特性兩個優點,許多學者都曾提出不同的特徵參數或改良方式以突顯不同的語音特性,本論文主要為提出一種合併特徵參數的方法,用以將不同的特徵值方法擷取出的語音特性結合在一起。經實驗結果發現,依此方法合併後的特徵參數能有效的提升關鍵詞萃取系統的辨識率,證明合併的方法能有效的加強聲音的特性。
    ;This thesis deals with the improvement on the speech feature extracting part in speech recognition. Feature extraction is a very important part in speech recognition, by having two advantages of reducing the amount of data and highlighting the characteristics of voice. Many researchers have been published different extracting methods or improving methods for speech features for highlighting different characteristics of voice. This thesis presents a method for combining different speech features, and binding the characteristics of different feature methods together. The result of our experiments showed that the proposed method improves the recognition rate of the keyword spotting system, and also proved that the method can effectively improve the characteristics of voice.
    In the second part of this thesis, we apply the keyword spotting system to iPhone smartphone app and build a voice-controlled game to achieve real-time speech recognition.
