1. INTRODUCTION
Inordertostoptherecurrenceofcovid 19,boththe federal and state governments have implemented tight restrictionsandlockdownsacrossthecountry.Gatheringsof 25peopleareallowedunderthenewlimits,althoughoffice attendance is limited to 15%. Students have access to lectures and examinations over the internet. We must strictly follow these instructions to protect our own and others' safety. However, because exams are conducted online,it ismoredifficultforvisuallychallenged pupils to take the exams. Today, Online Examination System is consideredafastdevelopingexaminationmethodbecauseof itsaccuracyandspeed[1].Thereareanumberofreasonsfor thedelaysinmanualexaminationmethods.Filteringresults,

Theprotectionof theIt'salsoatrickytaskthattakesalotoftimeandwork. Onlinetestingisoneofthemostessentialaspectsofonline education.

There are many online examination systems on the market: A Web Based ExaminationandEvaluationSystemforComputerEducation.

The “E blind Exam Portal'' is an MCQ based assessmentsystem.Itprovidesauser friendlyatmosphere forbothtestorganizersandstudentstakingexams.Moreso, thereisa reasonablelevel ofsecurityandintegrityonthe conduct of examination [3].

Saving time is one of the perks in having an Online Examination System [8].This will help to improve the current educational system for blind people who want to work. Promising effects have acquired the use of this approach, which displays huge development over the present techniques [9]. We will add subjective type questions in this project [10].Thus, traditional classroom Learninghasthedisadvantagethatit'soflimitedusetoonly thosestudentswhoareabletoattendthelectures.

2. EXISTING SYSTEM
Intoday'ssociety,blinduserscanaccessinformation throughavarietyofinterfaces.Onefrequentwaythatblind people have been designed to utilize is voice recognition, whichisadevicethatrecordsspeech.Wheretheinformation hasalreadybeenrecordedinaspecificformat,blindpersons shouldbeabletoheartherecordedcontentinthatrecording systemsothattheymayeasilyunderstandthecontentand learn in their favorable way, as well as engage with the systembyprovidingvoiceinput.Thesebasicmethodshave been explored by blind persons to demonstrate their abilities on a variety of platforms using a variety of equipment.
For example, there is functionality on the iPhone thatallowsblindindividualstointeractwiththedevice.If users press any button or use the display option on the iPhone, it is meant to reply as quickly as possible by providing speech output. As a result, blind persons may utilize all of the phone's features (for example, they can navigate, chat, send text messages, listen to music, watch videos,etc.).
2.1 DISADVANTAGES OF THE CURRENT SYSTEM
Thecurrentsystemsarequitetime consuming.
Manuallyevaluatingtheexamisdifficult.

7. CONCLUSION
5.2 Speech recognition
Speechrecognition,alsoknownasautomaticspeech recognition(ASR),computerspeechrecognition,orspeech to text, is a capability whichenablesa program toprocess human speech into a written format. While it’s commonly confusedwithvoicerecognition,speechrecognitionfocuses onthetranslationofspeechfromaverbalformattoatextone whereasvoicerecognitionjustseekstoidentifyanindividual user’s voice. Speech recognition, the ability of devices to respond tospoken commands.Speechrecognitionenables hands free control of various devices and equipment (a particularboontomanydisabledpersons),providesinputto automatictranslation,andcreatesprint readydictation.
Thisinitiativewouldbeveryvaluableforallblindpersons andphysicallychallengedpeopletobeabletoreadilyadmire their talent through an online assessment. Students'skills and knowledge will be improved by the addition of this initiative.Italsoreducestheneedforpaperandsavestime. We will produce a comprehensive application with an interactiveinterfacefordisablepeopleaspartofourproject. Examineescansimplyadministertheexambyusingsimple voicecommands.Asaresult,physicallychallengedpeople can take exams like any other person withoutdifficulties. Theyhavebeenabletoattendnumeroustestsinthefuture asaresultofthis,andwewillattempttoimproveasmuchas possibleinthefuturebasedontheinputwehavereceived. Thisprogramaimstoprovidetotalusability,supportability, portability, and practicality for users to take an online examination like a normal individual. A visually impaired individualcanparticipateinanycompetitiveexaminations conducted by organizations using an internet facility by utilizingthisprogram.Asaconsequence,thepercentageof visually impaired people who participate in competitive examinationsmayincrease.
