command. Voice commands are stored in large groups like libraries. You can import all seven voice commands in the library into the recognizer. This means that seven commands are valid at the same time. This board has two control options: Serial port (full function) and General input pin (part of function). Common output pins on the board can generate different types of waves while recognizing the corresponding voice commands.

and their function keeps enlarging. So this development of technology gives a discrete environment for educational purpose. Constructing a smart learning environment supported by a learning platform is the key area of experimentation in the educational fields nowadays. This development of smart learning environment has been advanced in the covid 19 pandemic. The idea mainly proposes a smart learning assistant with raspberry pi which is economically affordable and commercially available products.

Speaker: Adding a USB powered speaker to the Raspberry Pi is one of the easiest ways to play great audio from this project. It's also the ideal affordable speaker option for the Raspberry Pi 4 module. With just one USB connection, no additional cables, power adapters, or charging process. This is the simplest and most compact audio option on the Raspberry Pi. The device has two speakers and is powered by one Raspberry Pi connector.

1. INTRODUCTION According to the researchers the students needs oneon-one interaction with a personal teacher for the effective learning. However many schools, colleges and university finds it hard to give such individual tutor. The increasing number of schools, colleges and university make mass lectures with more than 100 students per lecturer and also the open online courses have more than 1000 participants make interaction with the lecturer even

Display: The Raspberry Pi Touch Display is an LCD display that connects to the Raspberry pi via DSI. In some situations, it can be used with both HDMI and LCD displays simultaneously.

more difficult to learn. In last five to ten years it is shown that the computer based teaching system is more effective than human teaching system. Therefore this paper mainly deals with computer based easy tutoring system which is a smart learning assistant.

Input: A corrosion-free Type-C USB cable that makes it very easy to transfer data between the PC and host board, making it ideal for use with Raspberry Pi 4 and other USB Type-C devices. Not only does this cable use power lines, it also has high quality copper wire that is essential for longterm use. The high-quality tactile material is ideal for longterm use and protects against normal wear. With a length of 1 meter, it can be flexibly used in a variety of applications such as a Type-C cable for mobile phones and other Type-C devices, as well as the Raspberry Pi 4.

1.1 System Architecture Raspberry Pi4: The Raspberry Pi 4 Model B is the latest addition to the popular Raspberry Pi series of computers. It dramatically improves processor speed, multimedia performance, storage, and connectivity compared to its predecessor, while maintaining power consumption similar to backward compatibility. For end users, the Raspberry Pi 4 Model B offers desktop performance comparable to entry-level x86 PC systems. Key features of this product include a powerful 64-bit quad-core processor and dual display support at resolutions up to 4K via a pair of micro-HDMI ports.

1.2 Implementation In general, a SPA (Smart Personal Assistant) is a computer program that allows us to interact with users on a particular topic or domain in natural language. The SPA mainly contains all types of software that allow people to interact with your computer. The main task of the SPA is to improve the user's cognitive or behavioral abilities. The main advantages of using SPA are low response times, low service costs, and high user satisfaction. Compared to other e-learning technologies, SPA are characterized by their ability to interact synchronously with the learner and

Voice Recognition module: Voice recognition module is a compact easy control process detection board. It is a speaker design module and supports up to 80 audio commands. All tones can be trained as commands. Users
