Hey DEV Community! 👋 I'm excited to share a project I've been working on: an AI-powered interview preparation platform. This tool helps users practice for job interviews using AI-generated feedback. Here's an overview of the project and some technical insights.
Project Overview
The platform allows users to:
- Answer mock interview questions via voice or text input
- Receive AI-generated feedback on their responses
- Get a detailed analysis of their strengths and areas for improvement
Tech Stack
Frontend: Nextjs with Javascript
AI Model: Google Gemini AI model for interview analysis
Speech-to-Text: react-hook-speech-to-text NPM package used for voice to text
Key Challenges and Solutions
Accurate Speech Recognition
- Implemented noise cancellation and used the Web Speech API for better accuracy Added a text editor for users to correct any transcription errors
Real-time AI Analysis
- Used web workers to run the AI model in the background, ensuring a responsive UI Implemented a queue system to handle multiple requests efficiently
Personalized Question Selection
- Developed an algorithm to dynamically select questions based on user performance and job role
Data Privacy
- Implemented end-to-end encryption for voice data Used tokenization to anonymize user data for AI training
