Introduction

I. INTRODUCTION

Our goal is to create a robot car that can be operated by a person's voice command. These systems are sometimes referred to as Speech Controlled Automation Systems (SCAS) . The above-mentioned system is a prototype of our design. The concept is to build a robot that will be controlled by voice instructions. A mobile phone is used to control the robot; there are numerous publications that demonstrate the communication between a robot and a smart phone. For remotely automating the robot, a smart phone is an excellent interface. It has a lot of features that can be useful. For the needed work, an android application with a microcontroller is employed in this design.

Bluetooth technology facilitates the connection between the application and the robot. The commands will be passed via the channel to the module, which will receive them. The goal of a voice controlled robotic vehicle (VCRV) is to listen to and respond to the user's commands. The system will require accent training after which the gadget will begin to grasp the commands given; the commands have been added via codes.

The primary goal of developing a VCRV is to analyses human speech and respond to pre-programmed commands. Backward, forward, right, left, and halt the robot are the most fundamental orders. The car will be controlled wirelessly using an Android smartphone; our goal is to create a robotic vehicle using advanced smartphone technology in a simple and cost-effective manner. Vehicles are now operated manually, and everything is done by the person operating the vehicle. Every action, such as starting and stopping, applying brakes, shifting gears, and accelerating, necessitates human effort. However, new technologies have been created in recent years that can be merged with traditional vehicles to create new vehicle forms. In this technological age, the advent of the gesture notion brings the physical and digital worlds closer together. We prefer technology over people for all perilous tasks. Although these robots were first operated manually, they can now be commanded through voice and gestures. The interface between the computer and human body language can be defined as this technology of gesture and voice recognition. This establishes the technological-human communication relationship. The goal of this project is to improve the robot's overall security while also simplifying the control method.

IV. WORKING PRINCIPLE

The android smart phone's microphone is used to recognise human voices. Using the Android operating system and Artificial Intelligence software, this voice is processed and transformed into English words. Speech recognition is a multidisciplinary subfield of computational linguistics that explores approaches and technology that allow computers to recognise and convert spoken language into text. Automatic speech recognition (ASR), computer voice recognition, and speech to text are some of the other names for it (STT). It blends languages, computer science, and electrical engineering expertise and study. Speech recognition has a long history in terms of technology, with multiple waves of key advancements. Advances in deep learning and big data have recently improved the field. The improvements are proven not only by the increasing number of academic articles published in the subject, but also by the widespread industry acceptance of a range of deep learning approaches in the design and deployment of voice recognition systems around the world.
