REVIEWED OF RELATED LITERATURE
INTRODUCTION
The goal of this study is to create a search engine that only allows voice-based Man-Machine interaction.The introduction of a revolutionary Voice-based Search Engine and Web-page Reader that allows users to command and operate the web browser using their voice. Existing Search Engines receive text requests from users and reply by obtaining relevant documents from the server and displaying them in text format.The authors of paper proposed an email system that is simple to use for visually challenged people.TTS (Text-toSpeech) module, STT (Speech-to-text) module, and Mail Programming Module (Compose, Inbox, and Sent Mail) module make up the system design.Speech-to-text is performed in this system using Artificial Intelligence (AI) via an API involving neural network models given by Google Cloud Speech-to-text to developers.Furthermore, it converts passwords or other credentials into hash functions using various Hashing Algorithms (MD5, SHA), resulting in stronger security than previous systems.The internet has become one of the most important aspects of modern life.Every human being uses the internet to gain access to knowledge and information. However, blind persons have difficulty reading these text materials, as well as using any internet-based service.The evolution of computer-based accessible technologies has provided many opportunities for the visually impaired all over the world.It’s a blindfriendly software architecture that integrates email and MMS messaging features into the operating system.Voice instructions and a mouse can be used to create a graphical user interface design, but the keyboard is required.RSS feeds are also used in conjunction with email to deliver a list of headlines, as well as notifications of new products and services.In addition, we have developed an application for you.Other apps, in addition to email, can be accessed with a voice command.The research project focuses on the development and implementation of a speech recognition device for visually impaired people utilizing the Raspberry Pi. The number of blind people is rapidly increasing, so the research’s main goal is to develop a simple, inexpensive, user-friendly, and compact device that allows visually impaired people to use multimedia applications of operating systems such as text, music player, and dialing system by integrating a GSM module.All of the aforementioned features are included on a low-cost Raspberry Pi board.At the period, one of the e-systems that is easily accessible to the blind is proposed. You can use the Viterbi method, as well as the voice-to-text and text-to-speech converters. The computational rule that works with the technology does not determine it to be the most acceptable word; yet, as soon as the user says it, it is spoken as your guessed word for a particular word.The user creates an account on the site that they are visiting for the first time.This system will mitigate some of the present system’s drawbacks.Sorry, but the Viterbi algorithm’s efficiency in reducing the number of errors will increase, requiring more space.

RESEARCH METHODOLOGY
INTRODUCTION
In this chapter, we described the research procedure for this study. A research methodology is a research process adopted or employed to systematically and scientifically present the results of a study to the research audience viz. a vis, the study beneficiaries.
RESEARCH DESIGN
Research designs are perceived to be an overall strategy adopted by the researcher whereby different components of the study are integrated in a logical manner to effectively address a research problem. In this study, the researcher employed the survey research design. This is due to the nature of the study whereby the opinion and views of people are sampled. According to Singleton & Straits, (2009), Survey research can use quantitative research strategies (e.g., using questionnaires with numerically rated items), qualitative research strategies (e.g., using open-ended questions), or both strategies (i.e., mixed methods). As it is often used to describe and explore human behaviour, surveys are therefore frequently used in social and psychological research.
POPULATION OF THE STUDY
According to Udoyen (2019), a study population is a group of elements or individuals as the case may be, who share similar characteristics. These similar features can include location, gender, age, sex or specific interest. The emphasis on study population is that it constitutes of individuals or elements that are homogeneous in description.
This study was carried to Effects of voice email system in visual impaired students academic achievement in junior secondary school computer studies. Selected secondary schools in Ibadan form the population of the study.

DATA PRESENTATION AND ANALYSIS
INTRODUCTION
This chapter presents the analysis of data derived through the questionnaire and key informant interview administered on the respondents in the study area. The analysis and interpretation were derived from the findings of the study. The data analysis depicts the simple frequency and percentage of the respondents as well as interpretation of the information gathered. A total of eighty (80) questionnaires were administered to respondents of which only seventy-seven (77) were returned and validated. This was due to irregular, incomplete and inappropriate responses to some questionnaire. For this study a total of 77 was validated for the analysis.
CHAPTER FIVE
SUMMARY, CONCLUSION AND RECOMMENDATION
Introduction
It is important to ascertain that the objective of this study was to ascertain a effects of voice email system in visual impaired students academic achievement in junior secondary school computer studies. In the preceding chapter, the relevant data collected for this study were presented, critically analyzed and appropriate interpretation given. In this chapter, certain recommendations made which in the opinion of the researcher will be of benefits in addressing an a effects of voice email system in visual impaired students academic achievement in junior secondary school computer studies
Summary
This study was on effects of voice email system in visual impaired students academic achievement in junior secondary school computer studies. Three objectives were raised which included: To ascertain the level of academic achievement of visually impaired students in Junior Secondary School computer studies before the introduction of a voice email system, to know level of academic achievement of visually impaired students in Junior Secondary School computer studies after the introduction of a voice email system and to ascertain perceptions of visually impaired students towards the use of a voice email system in Junior Secondary School computer studies. A total of 77 responses were received and validated from the enrolled participants where all respondents were drawn from selected secondary schools in Ibadan. Hypothesis was tested using Chi-Square statistical tool (SPSS).
Conclusion
Based on the data generated and results obtained from the data analyzed, the following conclusions are drawn by the researcher; that the application of computer based instruction in School will enhance skills acquisition, mastery of instructional content and improve academic performance of students with visual impairment. Also, since there is a significant positive relationship between students’ academic achievement and computer assistive technology, computer skills acquisition should be encouraged among student with visual impairment.
RECOMMENDATION
Based on this research finding, the researcher articulated the following recommendations.
- Curriculum planners and implementers should make computer appreciation a compulsory school subject for all students both in regular and special schools. This will help students with visual impairment not to be over dependent on tactile materials for learning.
- Training and retraining of special teachers on the use of computer assistive technology devices in educating students with visual impairment should be advocated by all stake holders in special need education. In a situation where most teachers of students with visual impairment do not know how to operate computer with special software programmed for teaching students with visual impairment is unhealthy for academic achievement of students with visual impairment.
- Stake holders in education should ensure that adequate infrastructure and ICT Facilities be provided in special schools and other schools that integrate students with visual impairment. A well equipped/functional computer laboratory with relevant software installed and be manned by a well trained and experienced personnel to facilitate teaching,learning and research
