First, the paper investigates the two most common speech recognition toolkits currently used, HTK and Sphinx, and apply these tools into Vietnamese speech recognition. Then, only HTK is selected to design an application that control a web browser (Google Chrome) and an application that control a robot. The results obtained give a comparison between the uses of the two tool kits for Vietnamese speech recognition. Index Terms—information technology, speech recognition, control by speech, hmm, mfcc, htk, sphinx, vietnamese. I. INTRODUCTION Human-machine interaction systems are increasingly invested these days, in which speech-based interaction methods is in high attention due to the nature of human voice. There are many toolkits for the implementation of speech recognition, but more prominent are Speech Recognition of Microsoft, HTK of Machine Intelligence Laboratory, and Sphinx of CMU. In the world, many research groups in speech-based interaction field can be listed such as HCI group at Stanford University, The Human-Computer Interaction group at Microsoft Research Asia (MSRA HCI), The Human-Computer Interaction (HCI) group at Department of Computer Science, University of Toronto. However, the majority of research work is about English, French, Spanish, Japanese, and only a little research work about Vietnamese. In Vietnam, there are also many research groups in this field, the most typical are assoc. prof. Luong Chi .
