Abstracts: This project is based on HRI (Human-Robot-Interface) & HCI (Human- Computer-Interface) technologies. Interacting with the robot, which connotes some anthropomorphic (human-like) appearance using Natural Language (NL), is one of the most prominent technologies in the field of “Artificial Intelligence (AI)”. This report covers almost all the parameters which are to be taken into consideration while designing “Speech Recognition (SR)” based system. Here we have chosen mobile robot because this type of robot is getting popular as a service robot in social context, where main challenge is interacting with the human..Two types of approaches has been chosen for Voice User Interface (VUI) implementation-1) Using Hardware SR system 2) Using software SR system & this has been included in chapter 1. Here Hybrid architecture has been used for general robotics design & for communication with the SR system, & also created grammar for the speech, which is chosen for the robotics activity in the predefined arena. Chapter 2 comprises of various complex algorithms like HMM, TOR, cross-correlation, auto-correlation, Viterbi decoding & many more DSP based algorithms for speech processing and synthesis. One of the important goal of this project is to introduce suitable interface for novice user. Chapter 3 contains the analysis of speech, where various parameters of speech as well as speech models like Filter-bank & LPC are included. In chapter 4, for the analysis results of different speech parameters as well as image processing parameters platform like MATLAB 2013 is used. Also various platforms like VB.NET, MY-SQL, JAVA and various microcontrollers / DSP processors like low power Atmega128, Atmega32, ADSP- 2100 family, HM2000 etc. can be used for implementing Speech Processing and Synthesizing. In last phase of this project, an image processing module (IP) will be implemented & interfaced with the speech-recognition module, which will add the image detecting capability to the existing SR based mobile robot, which will enhance its applications and usability to great extend.
