title = "An embedded system design for speech command recognition using improved AMDF-based pitch features",
abstract = "This paper presents an embedded system design for speech command recognition using improved AMDF (Average Magnitude Difference Function)-based pitch features. Compared with the autocorrelation method, AMDF has the advantage of low computation and high precision. This work presents three kinds of improvement for AMDF-based pitch extraction. One is the circular AMDF (CAMDF), one is the modified AMDF (MAMDF), and the other is modified and circular AMDF (MCAMDF). With the mixed segment containing voiced and unvoiced speech, the CAMDF-based method can give the pitch period of the voiced part and improve the performance on pitch extraction. Besides, dynamic programming and its modifications have been successfully adopted for speech command recognizer. The experimental results show that the proposed design obtained a noticeable achievement and would be utilized for various command-driven speech interactive applications such as intelligent toys, hand-free remote controlling, machine learning, and speech retrieval, etc.",
