. Introduction
By leveraging advanced natural language processing and speech recognition technologies, these systems enable users to compose, send, receive, and manage emails using their voice commands.They eliminate the barriers faced by visually impaired individuals when accessing and interacting with email platforms, allowing them to communicate more efficiently and effectively in the digital world [1].By providing a hands-free and intuitive interface, visually impaired users can navigate through their email accounts, dictate and listen to messages, and perform various email-related tasks with ease.The integration of AI enables the systems to understand and interpret natural language commands, enhancing the user experience and reducing the learning curve [2].In today's era, the internet has become one of the basic requirements for humans.Email is the most used communication medium.But blind people face trouble accessing the technology because of the fact that using them requires visual perception [3].Voice Based Email System, which will be useful for every person to access email without any difficulties.We will use the Viterbi Algorithm for this paper; it is a dynamic programming algorithm for locating the foremost doubtless sequence of hidden states referred to as the Viterbi path that ends up in a sequence of ascertained events.The drawback of this system is that the efficiency of the Viterbi algorithm decreases as the number of errors increases as well, as it requires more space.It has a computational complexity that grows linearly with the number of states and exponentially with the length of the observation sequence.This makes it computationally expensive for large-scale problems [4].Lack of exploration of alternative paths: The algorithm tends to converge on a single most likely state sequence without exploring alternative paths [4].This may limit its ability to capture uncertainty or consider alternative interpretations of the observed data.The Viterbi algorithm is not effective in handling uncertainty and ambiguity in decoding tasks.

Methodology
The voice-based email system for visually impaired individuals has been proposed as a solution to provide a convenient and accessible way of managing emails.The system leverages advanced Natural language processing (NLP)and Automatic Speech Recognition(ASR) technologies to convert spoken commands into email actions [5].The system supports voice commands for dictating emails, text-to-speech functionality for reading emails, and speech-to-text for writing emails, navigating the inbox, giving the count of unseen emails, and managing emails.This system is designed to be user-friendly, intuitive, and accessible, ensuring that blind individuals can easily navigate and use it with ease.Implementation of this system has the potential to greatly improve the daily lives of visually impaired individuals by providing a more convenient and accessible way to manage emails [4][5].This project presents a novel AI-powered voice-based email system designed specifically for blind individuals.
The above limitations are tackled by using ASR(Automatic speech recognition) process, which typically involves several stages, such as speech preprocessing, feature extraction, acoustic modeling, language modeling, and decoding.The first four steps here are used for removing the noise from the data, and the beam search algorithm is used for decoding [6].
• Beam search is a search algorithm that searches for the most likely sequence of words.It is more efficient than the Viterbi algorithm because it restricts the search space by only considering the limited number of the most likely hypothesis [15].It is also more flexible and parallelizable as it can be easily modified and can be run efficiently on multiple processors.
• And it still produces accurate results even when the observations are noisy when compared to the Viterbi algorithm.

•
Beam search maintains a set of the most promising partial hypotheses instead of focusing solely on the single most likely hypothesis like the Viterbi algorithm [7].This allows beam search to explore multiple possible paths, capturing a broader range of solutions and increasing the chances of finding better results [14] [15].
• It is effective in handling uncertainty and ambiguity in decoding tasks.By considering multiple hypotheses, it can account for the inherent uncertainties in the observed data and make more informed decisions.[8]Thisis particularly useful in speech recognition, machine translation, and other natural language processing tasks.

Experimental Procedure Selecting options through voice commands
It is going to ask the user to choose the options.Then the user has to select the options using the voice commands, which will be identified by Speech recognition.Finally, the system will give the audio output to the user regarding confirmation of the option.

Composing and Sending Email
This module starts with logging in to the mail of the user and then proceeds to compose by taking inputs like whom to send(i.e., receiver), the subject of the mail, and the message to be sent by using Speech Recognition and NLP[8] [9].The system connects to the user's email server and sends the email to the intended recipient using SMTP protocol.

Counting mails from inbox:
This module turns the total number of emails present in the user's inbox through audio as output [13].The NLP technique identifies the user's intent and extracts relevant information, such as requests to count the number of emails.

Reading mail from inbox:
The system first logs in to the user's mail and connects to the mail server.[10]The user gives the voice command in order to start reading the latest unread mail.[11][12]The system converts the email text(i.e.subject and sender's information) into spoken words throughText-to-Speechtechnology.This system is designed to be user-friendly, intuitive, and accessible, ensuring that blind individuals can easily navigate and use it with ease.Implementation of this system has the potential to greatly improve the daily lives of visually impaired individuals by providing a more convenient and accessible way to manage emails.This project presents a novel AIpowered voice-based email system designed specifically for blind individuals.

Future Enhancements
Integration with virtual assistants and smart home devices: Connecting AI voice-based email systems with popular virtual assistants like Siri, Alexa, or Google Assistant would provide visually impaired users with seamless integration into their existing smart home ecosystems.They could access and manage emails using voice commands through various devices.Accessibility across platforms and devices: Ensuring compatibility and accessibility across multiple platforms and devices, such as smartphones, tablets, smart speakers, and smartwatches, would allow visually impaired users to access their emails conveniently from different devices.Integration with other communication channels: Integrating AI voice-based email systems with other communication channels, such as text messaging or social media, would enable visually impaired users to manage all their messages through a unified interface, enhancing productivity and communication efficiency.
