ExamGPT - Conduct Oral Exam using ChatGPT

ExamGPT is a powerful tool that simplifies the process of conducting oral exams. It leverages the GPT-3.5 model from OpenAI to act as an interviewer, asking questions based on a provided topic. This project combines speech recognition, text-to-speech, and PDF handling to create a seamless oral exam experience.

Features

• Topic-Based Questions: Input a PDF document on the desired topic, and ExamGPT will generate relevant questions for the oral exam.

• Transcription: As the AI interviewer asks questions, the transcription of the speech will be displayed on the screen.

• Recording Responses: Easily record your responses by clicking the microphone icon. When you're done, stop recording.

• Text-to-Speech: ExamGPT uses the speechSynthesis library to convert text into speech for a natural conversational experience.

• Speech-to-Text: The project includes react-speech-recognition library to transcribe spoken responses.

1. Set up the client and server as described in the Installation section.
2. Provide a PDF document on the desired topic to the client.
3. Make sure the document is not too long and contains text. Must have a .pdf extension.
4. Start the oral exam, and ExamGPT will generate questions and provide transcriptions.
