A voice command identification method for an electronic device having a microphone matrix is provided. The method includes: obtaining a plurality of sound signals from the microphone matrix; executinga voice purify operation on the sound signals to obtain a purified sound signal and identifying a target voice signal from the purified sound signal; calculating a compound speech feature data corresponding to the target voice signal through a compound speech recognition model; comparing the compound speech feature data with a plurality of reference speech feature data in the speech feature database, so as to determine a target command mapped to the target voice signal; and executing the target command. 一种适用于具有麦克风阵列的电子装置的语音指令识别方法。所述方法包括经由所述麦克风阵列获得多个声音信号；对所述多个声音信号执行一语音纯化操作，以获得纯化后声音信号，并且从纯化后声音信号中识别一目标语音信号；经由一复合式语音识别模型来计算对应所述目标语音信号的一复合式语音特征数据；比对复合式语音特征数据与语音特征数据库中的多笔参考语音特征数据，以判断所述目标语音信号所映射的目标指令；以及执行所述目标指令。
