It is mainly because it allows the consumers to communicate with computers naturally using the spoken language and makes the users more and more comfortable to do their work. This report focuses on motor controlling using speech recognition. It uses an open source software library for speech recognition purpose named as Sphinx 4. It is a library entirely written done by Java programming and is a flexible framework. It incorporates the Hidden Markov Model (HMM) recognition algorithm. Eclipse IDE was employed to develop the recognition program using Sphinx 4 library. Arduino UNO microcontroller together with Arduino programming was utilized for motor controlling. A mobile platform is developed to present the motor controlling section. In this project I used simple commands such as forward, reverse, left and right to control the mobile platform. The communication between the laptop and Arduino microcontroller was established using serial communication. The main objective of this project is to apply the knowledge in mechanical, electronic and mainly programming which are key aspects in engineering sector. A capstone project submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Engineering in Mechatronics Engineering, School of Engineering and Technology Capstone Project (B. Sc.) - Asian Institute of Technology, 2014 Automatic speech recognition Asian Institute of Technology. http://203.159.5.9/ait-thesis/detail.php?q=B08957 http://203.159.5.9/ait-thesis/detail.php?q=B08957 170717 20260818090701.0
